RS JoinSurfaces

JoinSurfaces does not appear to work, I can replace it with "Rhino.Command (“Join”) and that works. (Yes, they are surfaces)

If lcase(extspec) = "igs" Then
  igsSelect = Rhino.LastCreatedObjects(True)
  Call Rhino.ObjectLayer(igsSelect, ParLayer)
  Call Rhino.JoinSurfaces(igsSelect,True)
  Call Rhino.UnselectAllObjects()
End If


Hi Don, this script works here:

Call Main()
Sub Main()
	Dim srfs: srfs = Rhino.GetObjects()
	If IsArray(srfs) Then
		Call Rhino.JoinSurfaces(srfs, True)
	End If

End Sub

Is it possible that this is a tolerance issue? If I remember correctly, the Join commands uses the document tolerance. If it fails, it will try using double the document tolerance.
Otherwise, maybe, could you send a small sample (with 3dm file) that shows the problem?

JoinSurfaces expects the surface (ids) in order. If you don’t have an order, use JoinSurfacesEx.

JoinSurfacesEx does not show up in the browser.

I’ll give that a try when I get back to the shop.
