HELP: How to work with corners of curves?

hi guys, i’m trying to work on curves and at some profile to it.

the problem is, when i look at the corners they look not nice.

if i click the 2d option instead, the corners look okay.

but then the problem is that the whole model gets flatened

You can play with the Twist Method and the Smooth value… but… well… it maybe easier to make your gadget in 2D first and "bend: them into 3D later , like sometimes done in real iron smithery… but you don’t even have to thing about lenght distortion or the correct heat :wink:
