Thanks for all the cool replyes and ideas guys.

Only problem with all those "solutions2 is that there is much more manual work than i've anticipated and wanted to do. I hoped to use MOI for great EPS/AI logotype creations to quickly import, extrude, bend/curve front faces and then do great looking fillet/chamfer on top which is problematic in regular polygonal or SubDs methods.
But now I'm stuck in MOI trying to solve some basic stuff like fixing AI files or recreating whole logo in MOI again which is then even slower than trying to do it in Polygons from start (i don't need to recreate logo curves on import in LWModeler) so i'm back to beginning of not using MOI for that :(.

Here is another very simple example I can't grasp in MOI why is it happening :(. I know it's probably my logic i.e. too much thinking about polygons so i'm trying to delete/remove some stuff which is easy in polygonal modeler but obviously not possible in MOI (for whatever reason) so please bare with me and try to explain me how to solve that.

Thanks i advance and Happy holidays :).
