I am fighting since several days with a part I am trying to shell with a wall thickness of 5mm for plastic injection.
Initially the part was a surface from Rhino which I succeed to knit and make a solid from with the knit feature.
However I am still unable to shell it. I think I have two issues : 1./ Radius size issue , 2./ Some faces being in improper shape at some area.
I don't know how I can solve this problem and I would be happy to have some insight from people who have more experience.
I included the file in attachment. Pwd to unzip is my id in the forum including (copy paste it to unzip the file)
