1.Overview

AnyCAD .Net Graphics Component is the professional graphics SDK for .Net developers, which can help you create 3D applications rapidly. This rapid graphics framework is focusing on 3d modeling, visualization and data exchange.

Our goal is to help our customers to make great 3D applications. If you have any issues, please contact us：support@

1.1.Capabilities

1.1.1.Modeling

Features of 3d modeling：

Primitive geometry modeling for point, line, polyline, spline, arc, circle, sphere, box, cylinder, cone, surface from points etc…

Compound: wire, shell, solid, compound.

Modeling methods for extrude, sweep, loft, revole, chamfer, fillet, projection, rotate, move, scale, etc…

1.1.

2.Data exchange

The standard AnyCAD .Net Graphics Component supports the following STEP,IGES,STL,DXF formats.

STEP

Support import and export. You can get the “tree”structure of STEP file with shape

names.

IGES

Support import and export.

STL

Support import and export. You can control the triangulation precision when exporting.

DXF (beta)

Support import DXF.

1.1.3.Visualization

AnyCAD .Net Graphics Component contains the visualization control for WinForm and WPF, which can help you to add the 3D control to you Form easily.

Features of visualization:

Default Camera operation

Z oom in/out, fit window, rotation, pan… and no coding required.

Selection management

Pick by mouse.

Add to object to selection/Clear selection set.

Query selected node and geometry, including sub Face/Edge/Vertex.

Set selection filter for node, group, face, edge, vertex…

Scene node management

Add, delete, find by id.

Create node group.

Render Style

Customize the face, edge, vertex styles, including color, line width, point size, and face

materials.

Display mode

Wireframe, shading, shading with edge…

Gradient background color settings
