Bug: placing bottom layer components rotated 180 degrees

[Tsillen]

When placing the bottom of a pcb Altium says they are rotated 180 degrees.

To combat this all rotations on the bottom layer should be deducted by 180 degrees to get the correct orientation.

I think this is also the case in other cad packages.

I seem to get similar issues even on the top layer - sometimes, the machine insists on doing a 180-degree turn to pick up the part (even when I have the part orientation set to 180 on the tape) and then undoes it when it goes to place the part.

Is the result wrong or just that it does unnecessary rotations? If result is wrong, do you have a file and a setup where this is reproducible?

The machine just does unnecessary rotations.

I could make another issue for optimizing the movements. However, the rotation is not the limiting factor and there are much more beneficial issues to tackle; in honesty, I don't think that issue would ever get attention. This peculiarity can stay.

Yup, no worries.
