How to get Geometry Data from Mechanical Model via Script

Mike.Thompson

You can find many relevant geometry entities with the script below. Each has their own properties like Face.Area or Body.Volume

Verts=[]
for Assembly in ExtAPI.DataModel.GeoData.Assemblies:
    for Part in Assembly.Parts:
        for Body in Part.Bodies:
            for Face in Body.Faces:
                for Edge in Face.Edges:
                    for Vertex in Edge.Vertices:
                        Verts.append(Vertex)
print len(Verts)

Thanks, Mike!

small correction use AllParts instead of Parts

in case of some geometries there are sub assemblies, that means Assembly can have more Assemblies, and in that case the above code would fail because the Assembly.Parts would return an empty list

but with AllParts it should return all available Parts in geometry

Verts=[]
for Assembly in ExtAPI.DataModel.GeoData.Assemblies:
    for Part in Assembly.AllParts:
        for Body in Part.Bodies:
            for Face in Body.Faces:
                for Edge in Face.Edges:
                    for Vertex in Edge.Vertices:
                        Verts.append(Vertex)
print len(Verts)

if we want the vertices associated with the face (edges will have 2 so in a square with 4 edges we get 8 vertices with the above - one the other hand we get 4 vertices if we get them from the Faces as below):

Verts=[]
for Assembly in ExtAPI.DataModel.GeoData.Assemblies:
    for Part in Assembly.AllParts:
        for Body in Part.Bodies:
            for Face in Body.Faces:
                    for Vertex in Face.Vertices:
                        Verts.append(Vertex)
print len(Verts)
