Ah, you're trimming in Rhino... The object order in rhino is not very well defined. Objects which have been changed most recently will typically be 'first' in the document. If you select a bunch of objects, and you window select them, then the order is maintained within the selection set. If you pick them individually though, the order is set by the picking.
Once the surfaces are referenced in Grasshopper, the order is fixed. (although it can be altered through the Collection Manager of the parameter in question, see the help file of the Collection Manager). The object order is not something which sticks around, like in a Vector drawing application. Every time an object is changed (new name, new layer, dragged), it will be moved the top of the object list. -- David Rutten Robert McNeel & Associates On Nov 14, 8:41 pm, BrentWatanabe <[EMAIL PROTECTED]> wrote: > http://groups.google.com/group/grasshopper3d/web/weird.jpg > > Trimming a rhino surface by linework > > On Nov 14, 12:05 pm, David Rutten <[EMAIL PROTECTED]> wrote: > > > Triangles?
