Problem with Mirror and "Distance and Angle Chamfer"

[buggeredupagain]

I came across a problem when mirroring a feature that had a "Distance & Angle" Chamfer. I set my chamfer to 60 degrees on a feature. When I mirrored the extruded feature and chamfer, the 60 degree chamfer did something that was not expected. The angle seemed to have changed position. This can be seen in the attached screencast. There is no audio as I do not have a microphone.

I have repeated the exercise using a 30 degree angle and the same shift occurs in the mirror.

Is this something that I am doing or is this a problem with Fusion 360?

I do not see an attached Screencast.  While you are at it, please attach the model you are having the issue with.  If you do not know how to attach your Fusion 360 follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save to your hard drive. Then use the Attachments section of a forum post to attach it.

Below is the Fusion 360 file. It is a simple example as I thought it would be better if I could reproduce the problem before asking for help. I thought that I could not reproduce the error, then the problem would definitely be me. I have no idea why the screencast is not visible. I will try again.

I tried a simple case, and Body Mirror and Component Mirror both seem to do the expected thing:

so, as @jhackney1972 said, we need more information.  What kind of pattern are you using?  Can you share the model with us?

I did the same thing with no problems. It was when I tried to mirror features that the problem occurred.

[jhackney1972]

If you mirror by features, you do get a different chamfer on the mirror side.  If you mirror by faces, it mirrors correctly.  @jeff_strater I will not call this a bug but you will have to decide as when I guess I get it wrong.

ah...  Feature pattern.  Yes, that is a bug.  Optimized works, but Identical or Adjust does not.  I will file that and have the team look at it.  Nice bug find, @buggeredupagain 

[edit] the Fusion bug is FUS-81214

Thank you. I am glad to find that I was not doing anything wrong.
