Hi nameless,
I read the manual (trying to comply with RTFM policies) but there is so much info I'm not able to memorize all and I actualy have it in pdf handy but when I get a problem and search, maybe I'm using wrong keywords.

Watched Chipp Walters vids and basically all I could find but rarely they try to solve exact problem I encounter. And as I'm not profi 3d artist and programmer I don't sometimes put 2+2 together like other folks here using MOI.

I do model but it's not my profession and when I model I rarely need very simple part. I was using Designspark mechanical for long time but as I need more complex parts I did research and found MOI. Now even when there is something I could do in 5 minutes in DSM I do it in MOI as I want to learn. Many cases I crash on moi bugs, downsides or my inability to realize thing like above case.

As DSM was more intuitive (for me) it's not that easy to use MOI with same ease.
I know it is more powerful but I have to change almost everything I'm used to in creating models.

I appreciate your help.
