Which rhinoscriptsyntax functions do you need to have implemented next?

Hi @siemen

Just script the ViewCaptureToFile command using rs.Command.

I would like to see rhinoscriptsyntax functions for splitting and trimming surfaces using a curve (or curves) on the surface (instead of using a brep as is used in the SplitBrep() and TrimBrep() functions). The functions could be something like:

SplitSurfaceByCurve(surface_id, curve_id)
TrimSurfaceByCurve(surface_id, curve_id, point)

Where surface_id is the guid of the surface to be split/trimmed, curve_id is the guid (or list of guids) for the cutting curve(s), and point is a 3d point on the surface indicating which portion to delete during trimming. The SplitSurfaceByCurve function wouldn’t have to be much more than a wrapper around the RhinoCommon Brep.Split method, but would hopefully be easier to use for those who aren’t as familiar with RhinoCommon.

Bump on rs.ObjectTopGroup…

First asked for here in 2014


Hi Mitch, Fyi, I added the function and some notes to the YT item

Thanks @Alain ! (I understand the limitations of this function, yes…)
