I am trying to make a square pipe of a square curve. Every time I make a square pipe I get a cross-section of a pipe as a rectangle. Switching the curve shape to 2D got me the desired result but as soon as I applied the transformation operations I got the error “Rotation/Location can’t apply to a …

This is not going to work. :smiling_face_with_tear: add If it’s the same way as the image below, it seems possible without deformation. :thinking: [scs] tsXX.blend (955.8 KB)

Are you sure scale is applied in object mode?

The answer is it already is square. The little square still has a square shape, but its placed a 45 degree at the corners of larger final shape. ( turn on wireframe to have a look) So the walls look smaller because,if you look through a square that stands in front of you at a 45 degree angle it no …

Check if profile curve is applied too, could be that

The problem is not with the scales of curves. They all are set to 1,1,1. The problem is with the default behavior of 3D Curves. I am getting the desired output with 2D Curves but the only problem with that it is limited to 2D plane only.

you are right, it creates a rectangle because (as Debuk says) it is using the corner as the profile on the flat, but if you change the angle of the Rail of your sweep it pops into a square. Excuse the messy shape, it just to show what I’m saying. [screen]

This is working, just need to change the mode to Complex on the Solidify modifier.
