Hello,

I am looking for a method to select by script an element close to another selection.

For example, in the case below, I would like to retrieve from a face selection (1) the selection of the nearest edge (2)

 

Is it possible ?

Hi GUICAD

Let me check and get back to you on this.

Hi GUICAD

Closest Edge to Secondary Selection...Text

active=Selection.GetActive()
if active.Count:
 item=active.Items[0]
 hitPoint = Window.ActiveWindow.ActiveContext.GetSelectionPoint(item)
 if isinstance(item,IDesignFace):
  closest=""
  dist=float('inf')
  for edge in item.Edges:
   project=edge.Shape.ProjectPoint(hitPoint)
   measuredDist=(project.Point.Vector-hitPoint.Vector).Magnitude
   if measuredDist(<)dist:
    dist=measuredDist
    closest=edge
Selection.Create(closest).SetActiveSecondary()

This should provide the key API needed, but you may need to change based on your needs. Let me know if this what you are looking for.

Regards.
