Excuse me, how can I set the origin coordinate and coordinate axis of the sketch, instead of a simple PlaneXY of origin. elements? Thanks #114

This isn't something I've ever done. Do you have an example using CATScript / VBA?

I've tried recording a macro that creates a positioned sketch using lines and point as reference and looking at the source code but that step isn't recorded.

It would appear you can't create new sketches that aren't sliding (defined with a single plane) with VBA (and thus pycatia): https://www.eng-tips.com/viewthread.cfm?qid=385399.

Thank you for your reply! I have solved the problem. I create a point and a normal, which decide a plane as my sketch reference. Then I can draw my sketch on this plane. Your code gives me a lot of help, thank you!

` hybridShapeFactory = part.HybridShapeFactory

hybridShapePointCoord1 = hybridShapeFactory.AddNewPointCoord(sketch_plane.origin[0], sketch_plane.origin[1], sketch_plane.origin[2]) hybridShapePointCoord2 = hybridShapeFactory.AddNewPointCoord(sketch_plane.origin[0] + sketch_plane.normal[0], sketch_plane.origin[1] + sketch_plane.normal[1], sketch_plane.origin[2] + sketch_plane.normal[2]) reference1 = part.CreateReferenceFromObject(hybridShapePointCoord1) reference2 = part.CreateReferenceFromObject(hybridShapePointCoord2) hybridShapeLinePtPt = hybridShapeFactory.AddNewLinePtPt(reference1, reference2) reference3 = part.CreateReferenceFromObject(hybridShapeLinePtPt) reference4 = part.CreateReferenceFromObject(hybridShapePointCoord1) hybridShapePlaneNormal = hybridShapeFactory.AddNewPlaneNormal(reference3, reference4) hybridShapePlaneNormal.name = plane_name body.InsertHybridShape(hybridShapePlaneNormal) reference5 = body.HybridShapes.Item(plane_name) sketch = body.sketches.add(reference5) `

You can code like above to create a 3D point, a normal, and refer it as your sketch plane.

I would have and have done pretty much exactly the same. Thanks for the feedback!
