Hello, 

I have built a part with some weldments and I used the function "trim" to make my T and rectangular sections stop when they encounter the 2 vertical beams. It seemed to work but when I'm doing a mesh analysis the hidden parts are reappearing as you can see on the picture (circled in red)... I have tried everything I could, like putting a "no penetration" contact between my pieces but it didn't change anything. Your advises would be precious  

Thanking you in advance !

Victoria
