Example files are organized as a learning path, from zero knowledge to advanced processes. Extensive explanations are provided in the critical sections of each file, and all components have hints about their functionality. The files are numerically ordered to build up the knowledge from the ground up. Their typical file name anatomy is:
<chapter>-<example n.><Associated Rhino file><main example content> + <additional topics>_<Plugin (optional)>
For example:
02-02_base 2 Objects_Assemblage - Environment + circulation_ShortestWalk.gh
All example files follow a common Grasshopper Definition Anatomy, and are conceived with a sense of modularity highlighted by groups and text, so that certain parts can be copied and stored or reused in multiple scenarios.
The “PP snippets” folder in particular contains modular definitions for specific post-processing strategies. These can be copied and pasted in your definition (or directly inserted as a group) after the simulation part, plugging the missing input data cables. See using PP snippets
