Hello,

Trying to multiple sweep cuts across a face like below. Allows a single cut but the face needs about 90 repeated going left to right on the concave surface.

Error message comes back
But it will do a single? Lost as I performed the exact same task on a convex surface yesterday with no issues. Also it will let me enter each cut individually if i put it on a new sketch each time, but im not doing that.

Please help.

Hi OldOZNoob, can you share the file?

Hi Zx,

Hope this works !

Never shared a file

You can see the first one. Just trying to repeat that across the entire concave.

I took a look at this just to be sure because I figured this is caused by zero-thickness-geometry.

A sweep-cut is a boolean operation so it subtracts the "solid" you're making with your sweep from the existing solid. I manually performed that operation by creating your sweep as a solid and patterning it across the length. When I use Combine -> Subtract, I get this error. My advice is to do one of the following:
1) Get rid of this point in your sweep profile pattern. It needs to be a single enclosed profile (in most cases) 2) Your sweep needs to be made up of many single sweep operations (not really a good practice)

Make it a revolve cut and pattern it. I had to add extra reference geometry because you didn't start off the standard planes as the center and nothing was locked down. But it should work better. I would not use a sweep unless I had to, usually when the profile needs to change path in all 3 directions. Patterns will regenerate faster.

Thank you very much TT Evolve that's a great help.

@Alex B I'll give that a try also.

Thanks for posting Zx, these chaps have sorted it.

Cheers everyone!!
