Hi Guys,

I'm trying to use Thicken command to give a 2mm thickness to the wall of my object, but It doesn't do anything. I've tried to knite the surface, but this doesn't work either. does anyone know how to fix this problem? I have problem with shell and thicken, I make the surface of the object smoother and I've tried different formats, but still I haven't got any progress.

I've attached my file here. please have a look and let me know if you can help me. This takes so much time of me, I need to sort this out as soon as possible.

Kind Regards,

Masoud
