When I have closed extrusions, the following custom filter does not let me pick the extrusions one-by one, but it does allow me to window select them…
import rhinoscriptsyntax as rs def solid_filt(rhino_object, geometry, component_index): return geometry.IsSolid objs=rs.GetObjects("Select closed polysurfaces",16,custom_filter=solid_filt)
if I add extrusion objects explicitly, it works correctly.
objs=rs.GetObjects("Select closed polysurfaces",16+1073741824,custom_filter=solid_filt)
I have reported similar things before… I don’t expect V5 to be fixed in this case, I guess, but V6 hasn’t been fixed yet either.
