How can we create named selections containing the parts that have the same material

Erik Kostson

We have an assembly of parts that have different material assignments. How can we create named selections where every named selection (ns) contains only parts with the same material assignment. So say one ns will have all parts with a Structural Steel assignment, while the another ns will have all parts with a Copper material assignment etc.

The sample code below shows one possible way of doing this via mechanical scripting:

model = ExtAPI.DataModel.Project.Model
materials=model.Materials.Children

Parts = model.Geometry.GetChildren(DataModelObjectCategory.Part,True)
selId = []

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

for mat in materials:
    for Part in Parts:
        PName = Part.Name
        print(PName)
        for Body in Part.Children:
            Bmatname = Body.Material
            if mat.Name == Bmatname:
                BId = Body.GetGeoBody().Id
                selId.append(BId)
    Sel.Ids=selId
    ns=model.AddNamedSelection()
    ns.Location=Sel
    ns.Name=mat.Name
    selId=[]
    SlMn.ClearSelection()
