OK if I go to create>nurbs>primitive>square. Now we have 4 independent lines that form the square. Now I want to connect all these lines so that it's a closed curve(square). If I do edit nurbs>open close curve...it does not work.
So i tried selecting 2 curves and then attching them to each other. Which worked so I have a "L" shaped line then I attached the 3rd line and had "I_I" shaped line. My problem is when I attach the final 4th line it does not form a clean square but the 4th line attaches to the "I_I" shape in a curved form. Why does this happen???
