Redefine Assembly Extrusion Sketch- Is it available in API?

[Tiffany_Hayden_]

I would like to redefine a sketch that is consumed by an extrusion within an assembly. I just want to change which plane the sketch looks at for the assembly cut. I'm having trouble finding it in the API. I have tired going through both the sketch object and the extrusion object and came up blank. 

I've tried both planarsketch and Sketch objects. 

when going through the extrusion I don't see any relationship to the sketches.

Hi @Tiffany_Hayden_ 

The redefine plane method we do not have access to via the API for either a part or an assembly. I searched around on a few post and while people attempted a hidden version it seems not to be there. What does seem to work is to change the planar entity of the sketch. See this post here.

    
    sketch.PlanarEntity = partDef.WorkPlanes.Item(1)

I was just about to go down that path! lol

@A.Acheson I got it to work resetting the PlanarEntity on the sketch. Thanks!
