Oh, I also have no wire centerline, I am working from a supplied solid model from an unknown software. So I have not been able to sweep a modified wire shape.

I could get in trouble with my boss if I were to post any images, sorry. I am pretty new to 3D, so I did not think to slice it. I will give that a try. I also don't know how to add the centerline other than drawing it from point to point. I can do that on the straight sections easily enough but the curves don't have enough info, just a start and an end with no arc info. I am sure I am missing something simple, but I don't have the experience to know what it is.

Yeah, like I understood any of that.

A thousand words sometimes does not make a picture while a picture can be worth a thousand words.

Yes, you can make a profile slice.

I don't understand how you drew your wire in the first place, unless it were straight (which does not sound like it is) without drawing the centerline then extruding or sweeping a circle along it.

Without an image or an actual drawing to work with we are left we no good options.  I'm not interested in stealing your idea/design.  We probably work in completely different fields anyway.  It would be like a surgeon using a John Deere yard tractor to do brain surgery.  Ain't happening.  Know what I mean?

OK...mock something up that kind of shows us what you are facing and we'll use our imagination.  Post an image and we'll see where that leads.

This block has been sliced with a surface that had a bit of an unusual pattern.

Sorry, I understand I am not as clear as I could be. I did not create the geometry, it was supplied by a customer. I ended up copying the shape down in the Z plane, unioning and then doing a subtract. Maybe not the easiest method but it got me what I needed. Thank you for your help, many of your suggestions are things I was unaware of and I did learn from you.
