i've made a surface using loft, but when i tried thicken, it says that it can't be executed because it intersects itself.. is there a way to avoid this? i tried to take the edges of what should be my thickened surface, but when i draw the lines so they form the contour of the surface, there is just a bunch of lines and no surface is actually formed.. when i try to draw a simple triangle on the xy plane, the same happens, i see the contours, but no plane is formed

can somebody help me?

thank you very much!

grtz,

as you can see I managed to thicken it by reducing the thickness i wanted to have, on the front of the pic you can see the contours I was talking about, the upper edge is the curve of the surface i wanted to thicken, the lower edge is the same curve copied, but adapted so both upper and lower curve meet on the right side, on the left side i've drawn a vertical line, to create a closed surface, but no surface is formed...

thanks for your help,

and when i do so with the link I've allready posted here, it says "error in inserting object in current location".... but the problem with forming planes is solved, when I extrude or sweep a line like you said, i can form planes now. I thought that when you draw a rectangle, the surface bounded by the rectangle is automatically formed like in sketchup, but i guess autocad doesn't automatically do this or hasn't a command to fill a boundary?

I still don't know how to avoid the intersection problem in the thicken command, but there probably isn't a way?

thanks for the help!
