I am trying to do washer split on a surface. sometimes, I am not getting circular split as expected. please refer the below image. If i try multiple times only, I am getting proper circular split.

Procedure used:

I am using *createmark to select the innermost line &

*trim_by_offset_edges to split the surface with that line with some offset

i am getting improper split as shown below

You could try adjusting the geometry cleanup tolerance.

Hi @Ben Buchanan,

I tried changing the cleanup-tolerance between 0.01 to 1.

But, still I am facing the same issue.

Can you suggest any other solution

Thanks in advance

I was thinking you would decrease the tolerance. What are the dimensions of the part shown?

Inner radius is 5.8 mm and outer radius is 17.5 mm

That is strange. Try decreasing the tolerance just to check.

I tried reducing the tolerance till 0.0001. The issue is still there

Any other solution if applicable

Thanks in advance

Hi @Ben Buchanan

Is there any way to solve the above raised problem?

This issue comes once in a while, not everytime. So, geometry cleanup tolerance isn't helping much on this. Please help.......

Thanks in advance

I am not sure what else to try. Can you share a model where it is not working and maybe I can experiment on my end?
