Summary0004513: Sketcher mirror command incorrectly adds vertical/horizontal constraints when mirroring around non-axis aligned line
DescriptionWhen mirroring using the mirror command inside a sketch (there seems to be another command that mirrors an entire sketch as well), the result is messed up when mirroring around a non-axis aligned line. Specifically, vertical/horizontal constraints are incorrectly copied. These are no longer valid for the mirrored copy in this case. See attached screenshot, where the upper right geometry was mirrored around the construction line.
Steps To Reproduce1. Open sketch in attached file.
2. Mirror the geometry with respect to the construction line.
3. Observe that the result is not correctly mirrored, unless the vertical constraint is first removed.
TagsNo tags attached.
