Where can I find ProtoGeometry Library Source Code?
You probably can’t since that’s not exactly an open source project. There are handful of libraries in Dynamo that are not open source. Check on the Dynamo GitHub page: https://github.com/DynamoDS/Dynamo
which is open source on GitHub and will compile to c# with haxe.
this is not a library in Dynamo… but it would be a fun project to try importing it.
What about Ian Keough’s original Design Script code? The Design Script documentation contains several Geometry resources. Can you tell if this Design Script code is open?
