Mirror broken

[foriwohl]

Hello, I am currently working in an assembly where I have a part that I want to mirror. When I use the mirror tool the part mirrors. But they aren't parallel, the angle of the new part is 1 deg of (See pictures):/ I have checked all planes and settings in the mirror tool and cannot find anyone who has had a similar problem. So I am trying to see if anyone here has any suggestions on what needs to be fixed or is broken...

Hi! If possible, please share the file here. I would like to understand the behavior better. The mirror should work.

Many thanks!

Set your angle measurement precision to three decimal places and try your measurements again.  Rounding to whole degrees is not going to show small errors...

Here are the files for my assembly

Thanks. I didn't know there was a difference between angle and normal precision (aka. I didn't look at the setting for mirror tool). Now I don't get the conflicting angle measurements anymore 🙂

Hi! I took a look at the files. I think I know where the problem is. The Mirror isn't at fault here. The geometry and the components are not constrained orthogonally against the assembly's origin planes. But, the components are mirrored along XY plane. As a result, they will not be correct.

For example, right-click on "bundplade:1" -> iProperties -> Occurrence. You will see it has minor angular offsets. You will notice similar behaviors in other parts. You can also open the part in its own window and measure the geometry against the part origin planes. The geometry also carries minor deviation.

It is better to ground at least one component against origin planes. Then build other components on top of it.

Many thanks!
