Midpoint relationship broken in sketch

[kb9ydn]

Changing the arc radius in the sketch breaks the midpoint relationship.

The midpoint sketch constraint is not lost if I adjust the radius of the arc.  Take a look at the video.

Very weird.  That's not what happens for me.  First off I'm noticing that the dimension is yellow for you and green for me.

And if I try to change the radius I get this:

This would lead me to believe that maybe there is a setting that's different somewhere.  🤔

BTW, I'm on a Windows 11 PC.

The yellow dimension is because I modify my Environment XML file, it has nothing to do with Fusion functionality.  I have a hard time seeing the green color so I edit the environment.  I do not know how you applied the Midpoint Sketch Constraint in you model but in the attached video I offer my method which never fails for me.  Try it out.

Hi John,

Thanks for the suggestions but it's still breaking the midpoint constraint when I try to edit the arc dimension.  Deleting the midpoint and recreating it with your method doesn't make any difference compared to adding the midpoint with the midpoint tool.  It's really strange.

Are you on a different version of Fusion perhaps?  Like in the beta program?  I'm on 2602.1.25 x86_64.

[jhackney1972]

I am using the current release version of Fusion.

Hmm, ok.  I think we need some other people to try it so we have more data.

OK, I can reproduce both @kb9ydn and @jhackney1972 's results.  I think I know the setting that John has that you don't, and I only know this because I accidentally turned it on recently to test it.  It is this one:

John, do you have that checked on?  Because if I turn that on, I get the correct results, but it is misleading.  It is correct, but only because that sketch has exactly one dimension, so changing it does not really change the radius of the arc, it scales the whole sketch.  If I turn it off, I get @kb9ydn 's behavior, which is definitely a bug.  I'll log a bug on that.

[edit] - I created bug FUS-205084 for this problem.  Thanks for reporting it

[jhackney1972]

@jeff_strater, Yes I do have the Preference you have called out checked.  I unchecked it, tried @kb9ydn sketch and sure enough, I get different results, the same as he is seeing.  

[kb9ydn]

Interesting!  That's definitely it.  I have that setting turned off, and turning it on changes the behavior.

If I put another randomly dimensioned line in the sketch first, and then try to change the arc, it shows the bug again regardless of the sketch auto-size setting.

@jeff_strater Thanks for logging the bug!  I found another way to get where I wanted to go, so no further assistance needed.  Just wanted to get the bug logged and in the queue.

Thanks guys!
