[solved]Part-design mirror of mirrored feature not possible?

Postby dbecad » Tue Apr 17, 2018 9:17 pm

Good day,
i was trying to reproduce some geometry from another post to see if i could model it and the shape was calling for a double symmetry.

But it seems that you cannot mirror in part design WB an already "mirrored feature"? I had to use the mirror in the part WB to do it but it feels a bit broken as workflow goes.

Doing the same thing with only the mirror tool of Part WB is even more confusing as the body will suddenly appear in 2 locations in the tree and the dependency graph seems to be broken (axis & pads are outside of the body box)...

Note: I had to select both the "Body (Mirror #1)" and the "Body" to get this result. Selecting the "Body (Mirror #1)" only would only create 1/4 of the shape instead of the desired result.

So questions:
- is double (multi) symmetry feature missing from part design WB? or it's a limitation but could be added as a feature request
- is double (multi) symmetry using part WB (mirror file joined) broken?

Thanks for your help,
Cheers

In PartDesign you have to use the multitransform feature.

This can be done with PartDesign>MultiTransform feature:

Thanks ppemawm and chrisb, multi-transform does work beautifully.
I'll mark as resolve!
