:-) I did create half cylinder using Loft between 2 profile curves :-)

I just wish it was doable by two moves!

1- selecting the desired face!
2- scaling it!

Dear Michael I got you! the fact is I had worked with polygonal modeling programs in the past (mainly Blender) and I only did have access to Trial versions of Moi3D, fortunately this has changed!and by the beginning of the new year I laid my hands on Moi3D ( a super cool way to start a new year :-) ) so, I think you would see me more often here! with questions about features that I am more familiar with (considering my history with blender) !
