hi guys another simple and easy problem that I got, but As I said sometime small and easy things can be big headache, I am trying to create an door frame. so I created 2 curves which you see in the Attachment image, I applied the surface extrude option, It does work but that is not what i am looking for. I want to small curve be extrude from the point of the position that the curve in it, but the extrude happened from the first vertex or curve point of the second curve(long curve). I want to be extruded from the position of the mall curve. ?= why extrude option missed this part
