What I've done:

I've imported a .dxf file from AutoCAD, then I've converted the curves (the lines from AutoCAD) into a mesh and I created the walls using extrusions.

All good so far, but the UV Unwrapping seems to be rounded. How can I make an orthogonal UV unwrap? I'm getting the same result using mark seams

    $\begingroup$ Generally, if seams were assigned, and were assigned correctly, then unwrap shouldn't be round. It is round because somewhere it is not unwrapped correctly. In this case you can workaround that by using another options for unwrapping. $\endgroup$

  • $\begingroup$ Definitely a seams problem. Either the seams are at the wrong edges or there are no seams assigned at all. I bet it's the second, because there are clearly no seams visible in 3D view. $\endgroup$ Jul 27, 2016 at 23:33
