Sketch on Mirror Plane Bug?

I'm trying to sketch on the plane of a feature that has been mirrored. Problem is, when I change the angle of the base feature, the sketch on the mirrored plane feature becomes sick. Am I doing something wrong? See attached part file and video.

Hi @David_McMahon

 

 

 

I can see the same behaviour here with Your part.

But, what I can not clearly understand is, what Your intends will be.

 

What will planes 31, 32 and 16 be used for?

How are the sketches positiioned on their planes?

They are not fully constrained, but somewhere in "plane".

 

Maybe a different approach will let YOu model Your part easier and more stable as this use of reference planes.

 

Can You give us more infos about the final goal You would like to achieve so that I can think further.

 



regards
Wolfgang

Hawcad,

 

Thanks for confirming the issue. The video I posted was a simple example I put together to demonstrate the problem. I thought I might be doing something wrong. I'm really trying to create some sktech geometry to control a plane location. I'm sure I can figure out a workaround, but the fact that the sketch geometry does not stay constrained to the mirrored plane it was sketched in really complicates thngs.

Hi @David_McMahon

 

 

 

can You test wether a coordinate system instead of the planes will be changed associativeley?

 

There were situations in past where CS performed better and more stable than planes.

Hawcad,

 

Thanks for the idea. I tried that but had the same problem. See attached video.

Hi @David_McMahon

 

I have checked this issue, modelling a new part.

 

And I do not have a problem with the planes.

 

Please see a video attached.

Hi @arekkul

 

 

 

Yes You don't have a problem, but You also don't have a mirror feature in Your pathfinder.

 

The problem IMHO occurs with mirrored features and the use of such mirrored faces.

Hi @hawcad

 

yes Wolfgang,

 

I missed it. 

I confirm - it is a problem.

Thanks everyone for your feedback. I have narrowed the problem down to the boolean > subtract feature. I remodeled it as a mirrored cut and that worked fine. Still seems to be a bug with mirrored booleans. I have logged it with GTAC.
