Thickening sheets to form a solid.
Thickening sheets to form a solid.
(OP)
Hi.
How can I get a solid body from sheets?
For example I have I create a curved duct-like sheet sweeping a circle along a curved line.
(I know I could directly create a solid with the seep dialog).
But if I want to create a solid from the sheet I find it impossible.
I have the same problem with more difficult geometries.
If I use the "thicken" option with a offset large enough to cover all the void I get the error "cannot offset face. The offset value may be greater than the radius of curvature..."
I've also tried covering the extremes and sewing without luck.
The only way I know, though more complex, is to create a larger solid body and trimming it with the sheets.

I didn't mean that creating a solid while sweeping is not acceptable. I just did it that way in order to show that I can't thicken that sheet, but it was a quick example. In general, I'm speaking about sheets or any solid with voids.

Example attached.

If the ends are non planar, one must create the closing shape, sheet body. The contact edges of this sheet must be within the modeling distance from the target sheet when sewing.
The sewing operation will not trim or extend the edges in any way. - One can sew "anything" together by increasing the tolerance, but the deviation will still be there after the sew. It might not be visible in shaded mode though. Static Wireframe will show the deviation.
If you use the "trim and extend- make corner" and the final trim makes a watertight body, it will then become a solid body.
