Thanks for replys... However, my example isn't quite what should be... I thought 2d/3d pline curve entity - so only real new POLAR EXTRUDE command could be what is needed... I've posted this topic into Wish list for newer release... As there are many 3d commands that are built-in A2014 that are even more complex than this, I thought this will fulfill CAD arsenal... Lofting is nearest to what I was looking for, or suggested edgesurf command, but I really think this is what is missing - I often have this kind of situation (3 edges + apex point) and I solved this before with 0-line as 4th edge... But is this 0-line necessity?
