Iron Python keep selection

Scripting

I can select edges of a brep within an ironpython script. I can see the highlighted selection in Rhino, if I execute time.sleep(5). After the script is finished, the selection dissapears. How can I keep the selection within Rhino after code completion?

Hi @daniel.kowollik,

Can you share some sample code that doesn’t work for you?

Thanks,

Hi @dale,

I tried the following:

import scriptcontext
import rhinoscriptsyntax as rs

brep_id = rs.GetObject("select a poly surface", rs.filter.polysurface)
brep = rs.coercebrep(brep_id)
rhino_object = rs.coercerhinoobject(brep_id)
scriptcontext.doc.Objects.UnselectAll()

for edge in brep.Edges:
    rhino_object.SelectSubObject(edge.ComponentIndex(),True, True)

While I wrapped up this simple example, I found out that I can use another overloaded method of SelectSubObject, which has the additional bool argument persistentSelect:

rhino_object.SelectSubObject(edge.ComponentIndex(),True, True, persistentSelect=True)

@daniel.kowollik yes, simply adding another True to the arguments should solve your issue.

import scriptcontext
import rhinoscriptsyntax as rs

brep_id = rs.GetObject("select a poly surface", rs.filter.polysurface)
brep = rs.coercebrep(brep_id)
rhino_object = rs.coercerhinoobject(brep_id)
scriptcontext.doc.Objects.UnselectAll()

for edge in brep.Edges:
    rhino_object.SelectSubObject(edge.ComponentIndex(),True, True, True)
