Hi all, 

I am trying to apply a face split command to an extruded skecth using design modeler scripting and I am not sure how to do so. 

Attached is my code to create the sketch and extrude it.

Any help will be greatly appreciated

DesignModeler is in maintenance mode. Have you considered using SpaceClaim to do your geometry modifications inside Ansys applications?

The only script type that DM records is jscript and only in sketch mode. When they were first implementing sripting in workench application, they decided on python interpreter. And they started implementing python scripting in DM, but it was soon-after placed into maintenance mode, so they stopped the work on python scripting implementation DM. So there is some python scipting ability in DM, but it's not developed to the degree of Mechanical, SpaceClaim, or workbench. This is an old course in the Ansys Learning Hub:

You can have a python script and run your jscript code:

Must be in an extension scope when running from the ACT console for the ExecuteCommand to exist. Example:
ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(jscript_command_string)

[mjmiddle]

Within an ACT extension inside DM, it may be possible to split a face using the imprint under ExtAPI.DataModel.GeometryBuilder.Operations.Tools:

Or maybe the face split could be done as a slice.

The only way to do a slice in batch, as part of a user-defined feature in an ACT extension, is to do it as part of an extrude or sweep operation, since you can choose the option to slice while extruding or sweeping:
feature.MaterialType = MaterialTypeEnum.Slice
Example called by :

def generateSlice(feature, fct):
    builder = ExtAPI.DataModel.GeometryBuilder

    bodies=[]
    squarePri = builder.Primitives.Sheet.CreatePolygon([0.,0.,0.,1.,0.,0.,1.,0.,1.,0.,0.,1.])
    # You can apply the extrude to a sketch, line body, face, or surface body
    squareBody = squarePri.Generate()
    feature.MaterialType = MaterialTypeEnum.Slice
    extrudeOperation = builder.Operations.CreateExtrudeOperation([0.,1.,0.],15.)
    #extrudeOperation.Depth
    #extrudeOperation.Direction
    #extrudeOperation.Walled
    extrudeBodies = extrudeOperation.ApplyTo(squareBody)
    # doesn't seem to be a way to slice through only target bodies
    bodies.extend(extrudeBodies)
    feature.Bodies = bodies
    return True

Or it may be possible to make some python commands to insert the native "Face Split" feature you would see in the Outline and set selections and any other necessary options, but I don't see an examples of this done yet.
