Hello McNeelies,
As part of testing our BIG pipelines in Rhino 8 I’ve noticed a minor, but quite annoying, regression related to drawing stuff by implementing the DrawViewportMeshes and DrawViewportWires methods in GhPython. When drawing stuff with nothing else in the display pipeline (i.e. existing in the Rhino file or elsewhere being rendered by Grasshopper) a GhPython component will draw stuff just fint without implementing the get_ClippingBox method, and one can use the ZEA Rhino command to zoom extend all to the geometry being drawn. In Rhino 8 this is not longer the case:

Of course one can just implement the get_ClippingBox method to solve the problem. But it would be great if one didn’t have to (i.e. to reduce complexity/code).
Thanks and best,
