Negative space scaling/rotating #4331

Open sprior opened 5 months ago

What happened?

I started with a stl and I wanted to drill a couple of holes in the side. I scaled the original object, then selected it and created a negative space cylinder which I then scaled to 4.9mm in x and y and 20mm in Z. Everything's fine so far. But when I selected that negative space and rotated it 90 degrees around x it got distorted, the end face turned oval and the negative space was displayed more than twice as long. I did exactly this same exercise in Bambu Studio and it worked fine.

same in prusa 2.5, they corrected it in 2.7, will be after the merge.

a workaround: add a negative object before doing any rescaling. don't rescale the main object node, but only the selina.stl part node. then it should be okay.
