I have a PickHelper tool that can draw outlines of entities. There isn’t too much data that can be obtained from the Sketchup::SectionPlane API description (the plane method’s data is useful). Section planes inherit a “bounds” method from DrawingElement, but currently a section plane’s bounding box object has its corner method returning the same point for all 8 corners. Is this documented anywhere?
Perhaps it is related to GitHub issue tracker:
