Terrible decision to remove the old model editor (Magenta aperture) that was so good for aligning, moving etc. Exceptional for working with tricky angles. Def a step backwards there
It worked in the early versions of E3D with a couple of command lines, but then they totally got rid of it in newer versions
I cannot work out why they got rid of this feature in the structural module. It still exists in piping and mech I think.
They could still keep what they call the new model editor, as they do entirely different things.
