How to merge Named Selections with the same name prefix?

Nikos Kallitsis

Assume I have some Named Selections with the same name prefix, for example 'CONT_1', 'CONT_2', etc. How can I merge them into a new Named Selection using Mechanical Scripting?

You can use the following script to merge the Named Selections with the same name prefix provided by the user.

nsMergeList = ['CONT_', 'TARG_']
nsList = DataModel.Project.Model.NamedSelections.Children

nsToMerge = {key: None for key in nsMergeList}

for nsPrefix in nsMergeList:
    nsToMerge[nsPrefix] = []
    for ns in nsList:
        if ns.Name.StartsWith(nsPrefix):
            nsToMerge[nsPrefix].append(ns)
            
for key, value in nsToMerge.items():
    nsMerge = DataModel.Project.Model.NamedSelections.AddNamedSelection()
    nsMerge.Name = key
    
    nsMergeIds = [ns.Location.Ids for ns in value]
    nsMergeLoc = []
    for sublist in nsMergeIds:
        for item in sublist:
            nsMergeLoc.append(item)
    
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    selection.Ids = nsMergeLoc
    
    nsMerge.Location=selection
