How can we create named selections containing parts of the same type using scripting?

Erik Kostson

We have an assembly of parts inside Mechanical that have bodies of different different types, and we would like to create named selections where every named selection (ns) contains only bodies of the same type (e.g., solids), using scripting.

The below Mechanical python script does that automatically (copy/paste and run from the Mechanical scripting console):

 

 

model = ExtAPI.DataModel.Project.Model
sections=model.CrossSections.Children # get all materials

Parts = model.Geometry.GetChildren(DataModelObjectCategory.Part,True) # get all parts
selIdline = []
selIdsolid = []
selIdsurf = []
selIdres = []

SlMn = ExtAPI.SelectionManager
SlMn.ClearSelection()
Sel = SlMn.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)

for Part in Parts: # loop over parts
for Body in Part.Children:
if (Body.GeometryType)==(GeometryType.Line): # if the part sec. name is same as sec in loop
BId = Body.GetGeoBody().Id
selIdline.append(BId) # add to array storing parts
elif (Body.GeometryType)==(GeometryType.Solid):
BId = Body.GetGeoBody().Id
selIdsolid.append(BId) # add to array storing parts
elif (Body.GeometryType)==(GeometryType.Surface):
BId = Body.GetGeoBody().Id
selIdsurf.append(BId) # add to array storing parts
else:
BId = Body.GetGeoBody().Id
selIdres.append(BId) # add to array storing parts
Sel.Ids=selIdline
if len(selIdline)>0:
ns=model.AddNamedSelection()
ns.Location=Sel
ns.Name='LInes'
SlMn.ClearSelection()
Sel.Ids=selIdsolid
if len(selIdsolid)>0:
ns=model.AddNamedSelection()
ns.Location=Sel
ns.Name='SOlids'
SlMn.ClearSelection()
Sel.Ids=selIdsurf
if len(selIdsurf)>0:
ns=model.AddNamedSelection()
ns.Location=Sel
ns.Name='Surfaces'
SlMn.ClearSelection()
Sel.Ids=selIdres
if len(selIdres)>0:
ns=model.AddNamedSelection()
ns.Location=Sel
ns.Name='Rest'
SlMn.ClearSelection()
