I asked this question at https://grabcad.com/questions/cutting-surface-in-catia-v5r20?utm_campaign=newanswer&utm_content=joinconversation&utm_medium=email&utm_source=member-email
I could not add the tutorial and part model there.
I am trying to cut a surface from a sweep geometry in a block. I am getting the error
"A skin does not cut across one of the volume: the split cannot be computed"
I have attached the two images. Please advise how I can remove this error. I shall be grateful.
