Can someone tell me if its possible to create a rolled sheetmetal part with an overlap. I have a cylindrical ring with interlocking features (see attached sketch), that I want to draw in sheet metal. The part will be lasercut from a piece of tubing and the manufacturer needs a flat geometery, I can't figure out how to create this part in sheet metal.

Mike,

That's a nice looking model! (I'm curious about what modeling techniques you used.) Have you already tried to convert it to a Sheetmetal part (Applications/Sheetmetal)? I'm wondering how it will handle the unusual aspect ratio of thickness to "flat" width. Also, to create a Flat Pattern, you need some flat reference surface to stay fixed; sometimes in similar situations I have used a little flat tab addition to allow this. I'm assuming your meaning for flat is unrolling the cylinder, not extending what could be seen as rectangular wire. In principle, I don't see why the overlap, per se, should be a problem, but I've never tried it.

Mike,

I was wrong. It's been awhile and I forgot that you only need a straight edge, not a flat surface. Here's an example, part created in Standard mode, converted to Sheetmetal, then flattened.

Hi David,

Thanks for the response. I created my original model as follows:

1. Sketch curve as flat geometery.

2. Swept protrusion of wire cross-section.

3. Spinal bend to roll the part.

The issue is that I want to create the model in the rolled configuration and then have PRO/E convert it to the flat. The actual model I'm creating is much more complex than this and it difficult to draw as a flat. How did you convert your above model into sheetmetal, what did you use as your driving surface?

Thanks

Mike
