化工工艺设计涉及计算的软件介绍
化工工艺设计涉及大量的计算,主要的有工艺流程的模拟,管道水力学计算,公用工程管网计算,换热器设计计算,容器尺寸计算,转动设备的计算和选型,安全阀泄放量和所需口径的计算,火炬泄放系统,控制阀Cv计算和选型,等等。
这些计算过程通常都有专用的商业软件或者是工程公司自行开发的软件或者计算表格。
大的设计公司通常也会指定公司用于以上设计过程的软件或经过确认的表格。
下面就我的经验来看看常用的一些软件。
1.工艺流程模拟:ASPEN PlusPro IIHYSYS2.管道水力学计算通常是工程公司自备的EXCEL表格,没必要使用专用软件。
当然,也可以自己编制,一般来说使用CRANE手册提供的公式就足够了。
两相流的水力学计算相当复杂,自己编制费力不讨好,用公司内部经过验证的表格就可以了。
3.公用工程管网计算我用过Pipe 2000,肯塔基大学教授的出品,包括Gas 2000, Water 2000, Steam 2000等一系列。
Pipenet也是不错的选择。
有人用SimSCI的InPlant。
没用过,有用过的朋友可以介绍一下。
4.换热器设计计算HTRIHTFS这两个软件都可以。
常见的介质用HTRI更好,因为它的物性数据是经过实验得到的。
HTFS使用了ASPEN或HYSYS的物性数据,很多都是计算得到的,所以精度可能稍差。
5.压力容器尺寸计算(长度与内径)工程公司往往使用自制的EXCEL表格来计算容器尺寸。
内构件一般要提交供货商来设计。
计算容器尺寸首先要确定容器的用途:气液分离,液液分离,还是气液液三相分离。
然后要确定容器是卧式还是立式。
最后要根据物料属性,考虑是否使用Wire Mesh或其他内构件来除去微小雾滴。
以上三项是影响计算的主要因素。
6.塔设备计算塔设备的计算和内构件的计算通常要由主要的供货商来进行。
软件比如说Koch-Glitsch的KG-Tower和Sulzer 的SULCOL。
工程公司一般只提供过程模拟的结果。

化工设计院用PID图绘制软件
化工设计院用PID图绘制软件.rar
PID, 设计院, 化工, rar, 软件
PID 专业的流程图绘制软件包整合到auto cad 2007
方法很简单:
解压文件打一定的位置如D:
打开cad 2007 >> 工具>>选项>>文件>>支持文件搜索路径再此添加你解压的ctcad和dwg
两个文件>>确定.
在命令行输入menuload>>加载/卸载自定义设置>>浏览>>D:ctcad,选ctcad.cui,打开.>>加
载.
在菜单的最后会出现PID,添加成功了.呵呵.祝你好运!
其他版本的以此类推.
在2004中测试成功!
1、将2个目录添加到支持文件搜索路径中。
工具->选项->文件->支持文件搜索路径,添加
C:\CTCAD和C:\CTCAD\DWG两个路径;
2、增加菜单项。
工具->自定义->菜单->菜单组,加载C:\CTCAD\CTCAD.MNC;工具->自定义
->菜单->菜单栏,在菜单组选择CtCAD,点插入将PID菜单插入到菜单栏中。
此时,AutoCAD的菜单栏中将多出PID菜单一项。
此软件使用了HZTXT.SHX字体,如果没有插入的东西里面的文字不会显示,
字体上网上搜一下,把它放到Autocad安装文件下的fans文件中,如果想偷懒,则把fans 中的任意.SHX复制出来,改名为HZTXT.SHX在复制回fans文件夹,重启CAD。
搞定!。

化工工艺流程图软件破解版下载
我们在工作中经常需要绘制一些简单的流程图,我们经常用软件工具来绘制。
每款软件都有自己的独到之处,也有自己的缺点。
通过比较不同软件和工具的使用效果,我们总能选出适合自己的一款。
我们在这里说的流程图,仅仅指日常用到的常规的,用来表示某项工作的流程规划图,并不是指某项专业领域的流程图,当然以下叙述的软件中也有能绘制一些专业流程图的功能。
根据维基百科,流程图根据不同的用户群体,可以大体划分为四类:文档流程图、数据流程图、系统流程图和程序流程图。
不同的职业角色所需要绘制的流程图也不一样,或许你会问,这么多流程图是否有明确的分类标准呢?其实流程图作为图形化的表达工具,我们运用的过程其实是帮助我们思考系统在某个层面信息节点的控制。
所以,不必纠结它所属的种类,只需要结合实际情况使用和理解就好。
丰富的流程图模板和符号,有效提升工作效率亿图图示是一款专业绘制流程图的软件,它含有丰富的模板和例子,不仅满足我们画各类流程图的需求,如数据流程图、时间流程图和工作流程图等,还有几十种例子可供我们选择,极大方便了我们二次修改和创作工作。
还有海量的符号满足流程图的绘制需求,简单布局设置,只需要我们在画布左侧剪贴画里面,拖动需要的符号,即可直接使用,极大的提升了我们的办公效率。
我们以亿图图示为工具以绘制业务泳道图为例,教大家绘制简单好看的流程图。
第一步,下载并安装亿图图示,打开软件新建一个空白文档。
在左侧符号库里找到“水平跨职能图形状”,将符号直接拖进画布。
再将鼠标移动至画板中泳道图符号右上方即可设置添加或删除行数。
第二步,添加符号。
在左侧符号库中有绘制基本流程图形状所需要的各种符号,选中你需要的直接鼠标拖到泳道中。
第三步,添加连接线和关键文字说明。
菜单栏上方有连接线功能,鼠标双击图形符号,即可编辑文字。
当然,为了使流程图看起来更好看,可以修改泳道流程图的背景颜色、符号填充。

六大化学绘图软件的比较
Chemical Structure Drawing Softwares. Comparison of ISIS and Symyx (MDL) Draw, ChemDraw (ChemBioDraw), DrawIt (ChemWindow),ACD/ChemSketch and Chemistry 4-D DrawDr. Tamas E. GundaUniversity of Debrecen, POB 70, H-4010 Debrecen, Hungary, e-mail: tgunda2@puma.unideb.huInternet access: http://dragon.unideb.hu/~gundat/rajzprogramok/dprog.htmlLast modified: 29-06-2008IntroductionThe immense development of microelectronics has banished the use of typing machine, drawing pen, Indian ink and templates. Instead, text editors like MS Word, Corel WordPerfect, Lotus WordPro, etc. are of general use today. With the aid of these one can create professional looking articles and drawings, and a large amount of time for the rewriting, redrawing and making corrections can be spared as well. The creation of chemical structures with the conventional drawing software packages would be extremely painstaking and practically impossible. With publication in mind aesthetics and quality come to the front, ensured by built-in templates, bonds constrained to fixed length and angles, etc. Direct 3D editing is usually not possible – 3D features of a molecule can be visualised only by using the wedged/hashed bond drawing methodology. The availability of different tools (palette of fonts, arrows, lines and curves, arcs and other shapes or graphic primitives, etc.) is also of high importance. If a true 3D representation of the molecule is needed, its import from a modelling program or 3D database is the most feasible arrangement (although the recent drawing applications usually contain a simple 2D → 3D converter module).The presented drawing software applications work on PC/Windows or McIntosh platforms. DOS programs are not used anymore, although it is necessary to mention that several 18-20 years old DOS applications were clearly better in a few respects than recent mammoth Windows applications with many bells-and-whistles. An important requirement is WYSIWYG (What You See Is What You Get). Under the Windows OS most tasks (printing, screen and printer fonts, resolution or any other system wide parameter) are maintained by the Windows itself and its set-up is the determining factor. Another important point is the user-friendliness of the program. This means that the user interface of the program, which ensures the interactive two-way communication between the user and the machine, should be simple but effective. The information sharing with other programs should also be many-sided.In this the most popular chemical drawing software applications on the MS Windows platform are reviewed and a few others are mentioned briefly:•ISIS/Draw 2.5 Free (Symyx MDL)1(updated June 2003)•Symyx (MDL) Draw 3.0 (Symyx MDL) 1(updated June 2008)•ChemDraw 11 Ultra, ChemBioDraw (CambridgeSoft)2(updated September 2007)•DrawIt - KnowItAll Academic Edition 4.1 (Bio-Rad)3(updated May 2005)•ACD/ChemSketch 11.0 Free and CommercialJune2008) (Advanced Chemistry Development)5 (updated •Chemistry 4-D Draw 6.0 Pro and 8.0 Lite(ChemInnovation Software Inc.)6(updated June 2008)Mentioned briefly:•WinPLT, ChemPen, WinDrawChem, JChemPaint, MarvinSketch,JME Editor, BKChemAlthough all of these software packages (counting the two Symyx programs as one) are stand-alone applications, they are members of integrated suites as well, and they serve as the input modules of otherdatabase and modelling software applications or full information management systems.•ISIS/Draw and Symyx (formerly MDL) Draw belong to the MDL ISIS and the newer Isentris information systems. Symyx Draw is the updated, face-lifted new commercial version ofISIS/Draw. It has a new and more user friendly interface. A few new features – concerningmainly database use – have been added, a few drawing tools have been refined while few otherones are already not supported. As far chemistry is concerned the backward-compatibility is100%, but in the case of other graphical objects it is not fully compatible with its predecessor. Itis an alternative input modul to the CrossFire Beilstein database as well. Unless otherwisestated, referring to ISIS/Draw always implies Symyx Draw.•Chem(Bio)Draw is integrated with the Chem(Bio)Office and ChemNote. It is continuously developed.•SoftShell’s old and popular ChemWindow has melted into the KnowItAll application suite and has been split to DrawIt and ReportIt – separate molecular editor and general editor applications,the latter is to import objects such as structures and spectra, arrange them on the page, and addtext, annotations, reaction arrows, orbitals or other graphical objects – when I refer to DrawItlater, it implies always ReportIt, too. This ChemWindow → DrawIt transfusion is not withoutdrawbacks, assets and bugs. The DrawIt modules of the ChemWindow and Academic editions arethe same.•ChemSketch is the input modul of ChemFolder and several other applications of the ACD suite.It has several modules, extensions, and add-ins concerning the calculation of physical-chemicalproperties, import, processing and databasing of spectra and chromatograms, naming ofmolecules, prediction of NMR spectra, etc. A few add-ins of ChemSketch can co-operate withISIS/Draw, Symyx Draw and ChemDraw.•In this latest upgrade only the free Lite version of Chemistry 4-D Draw was tested; its drawing capacities and features are the same as those of the earlier 6.0 version. The downloadable 8.0 Liteversion had problems with starting up in demo mode and certain basic functions (displaying atom labels or implicit hydrogens) did not work at all. The commercial version of Chemistry 4-D Draw is integrated with its Chem4D database and naming modules.The extensions (add-ons, plug-ins, bundled programs) come with the purchased version, sometimes can be freely downloaded, sometimes must be purchased separately, sometimes are available as an Internet-service – therefore before making decisions it is highly recommended to visit the homepages of these programs and to inform, what modules are currently included in the price of the program & version being considered. These are briefly reviewed in Table 1 and the last part of this article. The database and other embedded functions of the programs are not considered in this review, but structure drawing capabilities and text functions have been probed in great details and aspects.As extended and detailed discussions of every feature are not possible, the most important comparisons are summarised in Table 2. Bold text indicates features, which have been considered clearly beneficial as compared to the other programs, while italicisation means weak points. Of course, we are aware of the subjectivity of such comparisons. On the other hand, only 10-20% of the users are advanced ones: those reading and studying the written or online documentation in detail, trying everything, and knowing such handy tools or tricks, which are unknown to the “everyday” user.InstallationThe automatic installer of the programs worked flawlessly in every case. As most of the programs comprise several optional modules, it is advisable to select the custom setup option, if available, and select only the modules really necessary. The installers usually provide some help in this phase, but these are usually quite laconic – phrases such as “this option installs the ChemKingKong module” are pointless to a fresh user.Generally speaking, programs which have specific input/output file formats usually use one or more specific file name extensions. These associations are always entered into the Windows registry. Most programs are able to deal with several other file formats, too, like the graphical, image or text editing software packages, and the chemistry softwares we are dealing with also fall into this category. During the setup process some programs are quite aggressive and change the file name associations set previously by others. Fortunately, none of the reviewed chemical softwares behave this way; ChemSketch is polite enough to ask in a dialog box how to handle the foreign file types (if the other program is also installed in your PC, don’t allow to alter the corresponding associations).File operations, data movementBeyond the basic file input and output operations, the export and import facilities to/from other applications are of high importance. For example, if one has to import a 3D structure from a modelling program or embed an illustration created by another drawing program.Support of foreign chemical file formats (filters)There are two basic chemical file types: program-specific sketch files, which include all drawing objects, and molecule files or molfiles, used mainly by modelling programs, these contain only the description of the molecules. From this respect ISIS/Draw and Symyx Draw are the most conservative ones, as they stubbornly handle only their own proprietary file formats (sketch files, molfiles, tgf files). Although ISIS/Draw seemingly supports several chemical and graphical export formats have, but these are not available in the free version (the solution is weird indeed: instead of a warning dialog or greyed out options null files are produced; in order to convert succesfully you need the auxiliary programs ConSystant and Chemeleon). Symyx Draw has sometimes problems with opening old ISIS/Draw sketch files (roundabout: open and re-save old sketch files with ISIS/Draw 2.5). Chemistry 4-D Draw accepts only MDL molfiles as well. However, MDL sketch (skc or tgf) files are supported by ChemDraw and ChemSketch, but be prepared for inaccuracies during the import: fine tuning of the imported sketch may prove necessary. Of course, the not mutually supported features or objects will not be imported. Bad news: DrawIt is not supporting the older cw2 format of its predecessor ChemWindow, on the other hand, it often crashes when trying to open ChemDraw files.To summarize, ChemDraw and ChemSketch are the most respected, they contain the highest number of export/import filters (although in spite of intensive beta-testing not all of them are bug-free).Support of Web-related file formats are also included in the latest versions (CML in ChemSketch and XML in ChemDraw); for the time being, these formats are in quite experimental phase yet and not of general use.Support of other graphical file type s and embedded objectsThis mainly concerns ChemDraw or ChemSketch as these two applications are the most suitable for creating big size posters containing a collection of several data types. If illustrations, charts, diagrams are to be imported from another application, instead of bitmap images (JPG, TIF, GIF, etc.) the vector or Windows metafile formats (WMF or EMF) should be preferred: the former ones cannot be resized without considerable loss of quality, so the printed images will look ragged. The JPG and other bitmap formats are suitable only for photographic images. Table 1. summarizes the import possibilities of different files and clipboard objects into the programs.B i t m a p i m a g e s(t i f , g i f , j p g , e t c .)W i n d o w s m e t a f i l e(w m f o r e m f )F r o m M S E x c e l v i a t h e c l i p b o a r dP r o g r a mf r o m f i l ev i a t h e c l i p b o a r df r o m f i l e v i a t h e c l i p b o a r dM S W o r d t e x t v i a t h e c l i p b o a r d t a b l e c h a r t M S P o w e r p o i n t s l i d e v i a t h e c l i p b .C h e m S k e t c h 11 n o y e s (d e p e n d s o n t h e s o u r c e p r o g r a m )y e s (n o t a l w a y s f l a w l e s s )y e s (s e v e r a l o p t i o n s a v a i l a b l e ) y e s (s e v e r a l o p t i o n s a v a i l a b l e )y e s (a s s i m p l e t e x t ) y e s y e sC h e mD r a w 11y e s y e s y e s y e s y e s (a s s i m p l e t e x t )y e s (a s s i m p l e t e x t )y e s y e sI s i s /D r a w 2.5 M D L D r a w 3n o n o n o n o n o n o n o n oC h e m i s t r y 4D D r a wn o n o n o n o y e s (a s s i m p l e t e x t ) y e s (a s s i m p l e t e x t )n o n oD r a w I t n o y e s n o y e s n .t . n .t . n .t . n .t .T a b l e 1.With the exception of ISIS/Draw and DrawIt the programs have support for converting and saving the drawing in other graphical bitmap formats. The lossless GIF or PNG file formats could be regarded to be the most important one as they can be directly used for creating web pages (by the way, a lot of graphical utilities are available on the web to convert a captured screen image to GIF or any other formats; to learn about the GIF, JPG and PNG formats read Appendix I.)The general editor ReportIt supports a vast number of spectroscopical and chromatographical data formats, therefore it is surprising that it has no input/output options for WMF, EMF and at least a few common bitmap formats. Nevertheless, the export/import via the clipboard was flawless.Pasting of chemistry into the text editor and back via the Windows clipboard ( dynamicobject embedding)Fortunately, there are no problems in the case of the most important task: the direct transfer of the drawings between these programs and other text editor applications. The general object linking and embedding procedure of the Windows applications is available: first time the drawing can be copied and pasted via the Windows clipboard or drag-and-dropped into the text editor. To edit later, double clicking on the drawing in the text editor (or using the right-click pop-up menu) starts the drawing program and moves the drawing into it automatically. The direct calling for the chemical drawing programs from another Windows application (or vice versa) is also possible (object insert).Unfortunately, embedded ChemWindow drawings in older documents cannot be opened from the text editor and edited in DrawIt, in other words, the “ChemWindow object” does not exist anymore in Windows. However, you can copy and past the drawing into ReportIt (or any other application) as an image.-Although the chemical drawings embedded into a MS Word, WordPro or WordPerfectdocument can be re-opened and edited by their creator program later, sometimes thisprocedure may fail: if the full document is interconverted (Word ↔ WordPerfect etc) or anewer version of the text editor refreshes an old document, the hidden link between theimage and its creator program may mysteriously vanish. As a result, the image cannot beedited anymore. Therefore always save your (complicated) drawings from the chemicaldrawing program in its native format, too!-When a sketch is pasted from any chemical applications to Powerpoint, a complex of datais inserted into it. This is usually unnecessary. Instead of using Paste, open Paste special...and select Picture (enhanced metafile). The amount of data is much less, and the Powerpointfile will be much smaller, especially in the case of many illustrations. Older laptops will begrateful.The drawback of this method is that chemistry is not pasted together with the graphics, inother words, you can't edit the sketch in the original program anymore by double-clicking onit. So apply it only in the case of the final sketch, otherwise you have to delete it and copy itagain from the drawing application.Generally speaking, direct import via the Windows clipboard is a complicated procedure behind the stage. When a program sends a drawing to the clipboard, a mixture of different formats is used: the proprietary format(s) of the application, MDL's molfile (in text or clipboard format), sketch or reaction file, different picture formats, Windows metafile format may appear in the combination. Some of these formats are supported by the target program, others not, or are misunderstood.An important feature is that ChemDraw, ChemSketch, DrawIt and Chemistry 4-D Draw are able to create multiple page documents or posters. Previous ChemDraw versions frequently crashed when using large multipage documents. This has been fixed in version 10.Quick search and previewAn extremely helpful add-on of ChemSketch and ChemDraw is the quick search for structures feature: quick previewing of existing documents without opening them. Other programs should also create a similar one. It greatly helps the location of a sketch, when a folder contains 200-300 of older ones. In ChemSketch it enables the users to search for chemical structures on their file system in different formats including SK2, MDL MOL, SDF, SKC, CHM, CDX, RXN, and PDF, as well as Word, Excel and Powerpoint documents and ACD databases, using exact or substructure search. The content of the matched files can be inspected in the preview window and opened in ChemSketch or in the application which created the file. In the ChemOffice suite, ChemFinder for Office is a similar stand-alone utility capable of browsing MS Office documents with OLE objects and ISIS and ChemDraw files. For the time being, it is somewhat slower and not bug-free compared to the previous utility. This feature is not available in the basic versions of ChemDraw and ChemSketch, because they depend on the search engine of the corresponding data base program.ChemSketchChemFinder for OfficeDrawing of chemistryThe basic operations, as for example the sprouting or free hand drawing of different bonds, the drawing and joining of rings, the resizing of elements or the whole sketch etc, are handled well by all of the five programs. The only serious drawback of ISIS/Draw in this respect that the moving of the different objects cannot be constrained to the horizontal or vertical direction, in Chemistry 4-D Draw it is cumbersome (entering of coordinates). ISIS/Draw supports only a minimum number of different bond types (not regarding the query bond types). Figure 1. depicts the available different bond types, not regarding normal 1-2-3 bonds. Some of them are query types as well, but can be used well in other special circumstances. Mainly by ISIS/Draw, ChemDraw and ChemSketch several database features are supported: query atom and bond types, advanced Markush structures (ChemSketch), chemically significant multicenter attachments to resonance delocalized fragments, polymers, reaction features, atom-atom mapping etc., these are not covered here. In ChemSketch there is a separate handy option button for the direct drawing of bonds with solid or dotted delocalization curves. Of course such structures, as simple drawings, can be assembled manually too.DrawIt ChemDraw ISIS/Draw ChemSketch Chemistry 4-D DrawFigure 1Chemically interpreted multicenter (coordinative) bonds are available in ChemDraw and ChemSketch.A drawback of ISIS/Draw that all of the versions of this program have problems with the printing of dotted lines or bonds when using certain types of printers (we tried different HP LaserJet and DeskJet printers). This have been fixed in Symyx Draw. A definite advantage of ISIS/Draw, ChemDraw, ChemSketch and DrawIt that nearly every parameter of every object of the drawing can be independently restyled and trimmed, a very useful feature in advanced hands (this was not possible in the previous versions of ChemDraw). In the case of Chemistry 4-D Draw the parameters of a full object can be modified, but not part of the object.When comparing atom properties, valence state, isotope mass, charge, among the five products Chemistry 4-D Draw is the weakest: it doesn’t support charge as atom property – only as a separate graphical object.ChemSketch applies pseudo (empty) atoms for the bent bonds, like those used in carbohydrates (Figure 2). Similarly, ChemDraw uses pseudoatoms for multicenter bonds, such as metal atoms coordinated to ferrocen. When converting to 3D structures within the suit the programs automatically eliminate these, but must take care when exporting such structures to another application. When three-dimensional structures are imported, the recent versions of the programs are capable of 3D rotation (with the exception of Symyx Draw). Each ofthe programs is able to the automatic addition of hydrogens, although these areonly implicit hydrogens, and the saved file will not contain them. ChemSketch hasan option to convert and add implicit hydrogens as explicit, physical ones. This feature is the less sophisticated in DrawIt, for example no implicit hydrogens are added to imported molecule files, or corrected when editing the bond order later.Chemistry 4-D Draw, when using its intelligent NamExpert feature, can create structures from chemical names in three styles: the generally used shorthand structure, the linear semistructural and the so-called Kekulé structure are the three available options:All of the programs have a “clean structure” function, which redraws and resizes selected structures or fragments to standardize all the bond lengths and angles. None of them has precedence over the others: they do their best and produce nice-looking structures, but may fail in more or less complicated ring systems.The basic default and user settings can be saved and recalled in all of programs, moreover, additional settings (styles) to produce documents according to the demands of a few common journals are also available.Line notations to 2D conversionSmiles, SLN or InChi strings (formulation of chemical structures in a line of text, used mainly in data base applications) are supported by ChemSketch and ChemDraw. When you open a file of this type you see something like this:CCN(CC)CC1OCCC(OCC)=C12OHOH HO H H O H H H HOHOFigure 2 1-hydroxy-5-phenyl-2-pentanoneCH 2C CH 2CH 2CH 2OC CHCH HCCH CHC CC C C O CC C C CCOH HH HHHH H HHHHShorthand KekuléSemistructuralOFigure 311Strings do not contain coordinates, therefore while the reconstruction of structures of small molecules works well, in the case of large cyclic compounds the reconstruction will be chemically correct but quite ugly looking. The best results were obtained in ChemDraw when using Smiles strings. For a tiny comparison see Appendix 3. (There are several commercial and experimental applications out there to transform line notation of big molecules into acceptable 2D drawings.) 2D → 3D and 3D → 2D conversion of structuresDelicate 3D structures should be imported from modelling programs. However, all drawing programs have modules or bundled programs, plug-ins, which are capable of 2D → 3D conversion. • • • • • ISIS/Draw: ACD/3D Viewer and 2D → 3D converter (add-on) ChemDraw: sister program Chem3D (can be called directly as Chem3D Preview window) DrawIt: bundled program 3DViewIt ChemSketch: bundled ACD/3D Viewer and 2D → 3D Chemistry 4-D Draw: sister program ChemSiteTake into consideration that apart from Chem3D, these modules contain only simple MM optimisation algorithms, and the produced conformer is usable only for presentation purposes. Using the peptide, carbohydrate and nucleic acid builder of the ChemSketch ChemBasic Goodies, complicate 3D molecules can be created by inputting their shorthand text abbreviation. The automatic conversion of 3D structures to the usual 2D shorthand drawings using standard bond lengths and angles has always been always problematic. This is very easy if you have Cambridgesoft’s Chem3D, too. When the ChemDraw panel is active within Chem3D in synchronized mode (the default case), edition or rotation of the 3D model is reflected immediately in the ChemDraw pane while the structure is on-the-fly converted to a 2D drawing (Figure 5). When the 2D model looks satisfactory, it can be saved or copied to the stand-alone ChemDraw program.Figure 412Full restyling of the sketches:Current settings can be saved from all programs and recall and apply later. Settings include such things as standard bond length, bond line width, margin width, font size and so on. Especially useful are the predefined journal settings (or style sheets). These worked in three programs as necessary, but in ChemDraw, when applying a style sheet to an existing document or changing document settings, not all of the new parameters are consequently applied. New documents will be drawn with the selected style, but the use of this feature is a bit complicated when an existing drawing should be restyled. When drawings are copy/pasted between two documents with different settings, structural text is changed accordingly, but captions not. It’s to be hoped that this glitch will be fixed in the next version of ChemDraw. In Chemistry 4-D Draw an existing drawing cannot be restyled in one step at all. Anti-aliasing: In ChemDraw 10 and ChemSketch 11 and MDL Draw a new feature is the optional drawing and/or export of sketches in anti-aliased mode: the elimination of the stair-step appearance of sloping or curved lines. This greatly improves the quality of drawings when exported to Powerpoint presentations or as images to web pages (Figure 5). Antialiasing has no influence on printing (the resolution of the printers is much higher). As it is a quite resource-demanding feature, in the case of slower, older computers and big multipage documents you may want to turn it off while the drawing is being prepared. The ChemDraw solution is the more advanced one: antialiasing is optionally used when pasting the drawings into other applications (Powerpoint, etc.) or saving as images or metafiles. ChemSketch uses only screen antialiasing (can be circumvented by use of a screen-capture application). MDL Draw doesn’t antialiase drawings when copy/pasting them.Figure 5. Probably the differences in the printed version are not as marked as at the screen.Other drawing operationsThe drawing of different lines, polygons, circles and arcs, curves, arrows, etc. were also tested. Of course, no advanced features of a professional general drawing program should be expected, but basic functions are available, and these are usually enough to create, for example, simple diagrams or13 biochemical sketches. In this respect ChemDraw and ChemSketch are the best: they contain more graphical objects than the other programs, on the other hand, these can be filled (simple or shaded) with colours and/or patterns. Isis/Draw has clearly lost its earlier leadership. Unfortunately, its newer version Symyx Draw made a backstep, smoothed curves and pattern-filled objects are not supported anymore The editing of Bezier curves (to create freeform, irregular curves or shapes) is the most advanced in ChemSketch and ChemDraw. These two applications were neck Figure 6 and neck, but recently Chemdraw is a hair's breadth ahead. With ChemSketch a shaded double DNA helix can be created in five minutes (). However, the new BioDraw templates of ChemDraw make the creation of DNA even more easier. The drawings A-E of Figure 7 were created with ISIS/Draw, although ChemSketch or ChemDraw could have also been used. Drawing F was produced with ChemDraw, because the rotation of letters and texts in the ISIS/Draw (and Chemistry 4-D Draw) is not supported at all. Drawings like A, C and E cannot be prepared with Symyx Draw, because smoothed curves are not available. Figure 8 was created with ChemSketch.CDescriptor 3AN1 XH H 2 H H H HBDescriptor 1CspheroplastDLClDescriptor 2O F N HN N C2H5 COOHaffinity 100 % Contraction spec. activity 75 50 25 0 10-5 10-4 10-3 10-2 10-1 Log concentration, mmolclosed circular DNAEACh A ED50 B CA4 quinolone moleculesADNA gyrase BBFigure 7 A-E – Isis/Draw, F - ChemDraw。

流程图,是一种比较简单的图表,画起来虽然简单,但是却也需要耗费不少时间和精力。
说到绘制流程图的工具,可能很多人会想到Office,微软的Word、Excel、PPT确实是办公中使用率最高的软件。
但是用来画流程图,并非是最佳的选择。
因此,寻找一款能够替代且专业好用的流程图绘制软件,也许是作为流程图用户的您,需要花费大量时间与精力去做的事情。
今天,终于不用再去苦苦找寻了。
让我来为大家介绍一款超高性价比的流程图软件。
传统的流程图用连接线指出各项工作顺序,对于新手来说,并不能掌握其中的规律,画出来的流程图,让阅读者花费很大的精力去了解整个流程和算法。
如果我们可以借助模板,这样就可以规律性的修改各节点的顺序组成,让阅读者更容易从头到尾的看下去。
亿图图示正好满足以上优点,还有额外三大特点:操作简单、模板丰富并且兼容多种文件。
流程图模板
亿图图示可以创建多种类型的流程图:事件流成图、工作流程图和程序流程图等等。
流程图例子
丰富的例子可帮助我们快速绘制想要的流程图框架,方便二次编辑。
选择好专业的流程图工具,接下来我们详细的了解一下绘制步骤。
首先下载并安装亿图图示软件,选择新建流程图,创建空白文档进入画布,当然也可以选择自己喜欢的流程图模板点击进入。
其次,在左侧的符号栏里有各种符号,用来搭建整个框架,选择需要的符号,直接拖拽到画板位置,利用软件的网格和标尺定位好图形符号的位置
最后,记得双击图形,输入补充文本关键词。
如果想要流程图显得不那么单调,可以通过上方的样式栏更换主题颜色,使得流程图更专业。
