Description
How do you go from crawling to running Dynamo for Revit? Baby steps. Jay Polding will methodically walk with you through 4 simple and practical examples that will save you pain and time in uncovering the basic principles of Dynamo. You can expect to walk out of this class with 7 practical Dynamo example files and the confidence needed to run with Dynamo.

Introduction
Dynamo not Ideal when…
∙Distributing to many people, without training
∙Large, multi-stepped routines
o Only runs one graph at a time
∙Tracking ‘live’ information.
o Not intended to be running constantly
Dynamo is Ideal when…
∙Automating something that is repetitive and takes a long time o i.e. filling out Room info from Excel, Making Views ∙Copying information from one place to another
o i.e. schedule Filled Region area
∙Made and used by one person
Installing Dynamo
Dynamo should be pre-installed in the Manage Tab in Revit 2017. If not go to this link: /download/
Example 1: Make a Wall in Revit using Dynamo Files: Make a Revit Wall Using Dynamo.dyn
Rule: Always set Run to Manual when starting a new Graph Tip: F5 key on keyboard runs Graph
Rule: Always save Revit and Dynamo BEFORE running a Graph
Tip: Look at Symbols in description
Tip: Hover over Node Inputs to get default values

Example 2: Make Flexible Auditorium Seating
Files:

Auditorium Seating.rvt
Tip: If you close and reopen a Dynamo Graph in the same file Dynamo will try to adjust the same objects.

Tip: Dynamo only ‘Gets and Sets’ to Instance Parameters by default. Use Rhythm Get and Set by Ty pe or Instance Nodes.
Tip: Use Clockwork Node Math.RoundtoPrecision

Useful Nodes:
Dynamo Terms
Node: Command
Graph: The finished product. A dyn file. A bunch of Nodes wired together to do something. Similar to the word ‘Script’. Sometimes called an App or routine.
Canvas: Area where you work and see stuff
Curve: Line(s) or Arc(s), or both. Outline
PolyCurve: Lot of Curves together as one. Similar to PLine in AutoCAD
Double: Number which can contain decimals. (Dynamo counts from ‘0’. In other words if there are 4 items they will be listed as 0,1,2,3)
Integer (or Int): number which cannot contain decimals
Lacing: Cross Product will array in all directions
Boolean (Bool): True or False. Can be used as an on/off or yes/no switch. Most of the time all you need to do is click the opposite to what is there and then Run.
Common Node Combinations
Select everything on a particular category
Get an Instance parameter from one place and set it into another place
Double-Click on Canvas for a ‘Code Block’. This can either be a String or a Number. If it’s a String add “ ”. If it’s a number just ty pe the number.
Filter by Boolean Mask. A way to filter a list by a criteria
Get a Type parameter from one place and set it into another place
Get Wall Curves (and other important information)

Spatial Separation (Percentage of unprotected openings)
Files:
STEP1_Filled Region Areas_Spatial Separation_Make Views.dyn
STEP2_Filled Region Areas_Spatial Separation_Get and Set Filled Regions.dyn
rac_basic_sample_project_Filled Region Areas_BEGIN.rvt
rac_basic_sample_project_Filled Region Areas_COMPLETE.rvt
Notes:
The purpose of these Graphs is to make a Schedule showing unprotected areas on building faces. This routine is run using two separate Dynamo Graphs/Files. The first one makes Views and applies View Templates to those Views. The second Dynamo Graph is looking for specific Parameter and Filled Region names (which are set in the example file.) It then will write the key data to one of the Filled Regions.
Steps:
1.Open rac_basic_sample_project_Filled Region Areas_BEGIN.rvt
2.Open and run: STEP 1_Filled Region Areas_Spatial Separation_Make Views.dyn
3.In Revit ‘Exterior’ Views make Filled Regions for Exposed and Unprotected areas. Detail Groups
are provided to speed this up.
4.Close and Reopen Dynamo
5.Open and run: STEP 2_Filled Region Areas_Spatial Separation_Get and Set Filled Regions.dyn
a.If you want to run the Dynamo Graph again without closing and reopening Dynamo then
find the Boolean node (far left on Canvas), click the opposite radio button and run.
6.Look at ‘Site Plan’ Sheet to make sure the Exterior Wall Areas have been fil led out.
