Hi How should I use this when it’s a sealed class? I tried to derive it and I get an error: [image] When I tried it differently I get a result None: [image] Update: ignore the typo with the Flatten, the result is the same even if it is: drw_params.Flatten = True

Thanks @Helvetosaur , Thanks @rajaa These two threads helped me get started. [image] Make2D in RhinoCommon? Scripting I know Make2D has made it into Grasshopper in the WIP - has the functionality been exposed directly in RhinoCommon yet? (I didn’t find it…) Thanks, --Mit…

I got something: [image] Now how do I add this to the document? Is this a curve?

I found this thread: [image] Exploding RhinoCommon HiddenLineDrawing segments Scripting So once I have computed my HiddenLineDrawing, I have a collection of segments which are stored in .Segments… hdp=Rhino.Geometry.HiddenLineDrawingParameters() hdp.AbsoluteTolera…

Here is a sample that you might also find helpful. https://github.com/mcneel/rhino-developer-samples/blob/6/rhinopython/SampleMake2dSnapshots.py – Dale

@dale can I automate the snapshot creation? Say, I know which layers to be visible and I do this with a script and I create a drawing with a script, can I put also snapshot creation in a script?

[image] dale: But the command is scriptable. I see only one command “Snapshots” and what it does is to open the panel. How could I create new snapshot and select the states?

Run -snapshots (notice the hyphen…). – Dale
