Beam mirrored section

[j_pawlowskiQ4YZQ]

Hello,
Two beams with the same cross-section are placed in mirrored positions using 3D snap. When I attempt to mirror one of them to the correct position, it only rotates 180 degrees.
How can I properly mirror the section?

Mirror relates to the Workplane you are in and the Mirror line so this would influence the result can it be achieved by trying to mirror in a Plan View?  

Try Setting a Reference Plane to the Top of the Beam prior to Mirror.

When I mirror in section view and set 180 in cross-section rotation parameter, the cross-section of the beam changes to the correct position. However, when I try to rotate it to achieve the correct curve orientation, it reverts back to the incorrect cross-section.
What’s more strange is that this issue only occurs with a few of the beams, not all of them.

It could be a limitation in the Beam/Family where if orientated differently it cannot resolve the shape so reverts back.

Difficult to fully determine without the Beam for reference.

The family is in the attachment. I hope it will be helpful.

It is definitely the way the Beam Shape works with the Mirror functionality and its relationship to how it was placed and the Level

I tried using the Array Tool Instead?  Create a Dimension to find the Centre Point > Radial Array Move To: 2nd Pick Start of Beam then End of Beam

Hi @j_pawlowskiQ4YZQ 

Thanks a lot for posting your question to the forums!   Has the solution suggested by @jay_colcombe helped with your issue?
 
We look forward to hearing back from you with more information so we can help you as a community!

This works.

1. create beam in any possition 
2. create arch in correct start/end orientation 
3. Align 

Thanks a lot for help 😄

Amazing @j_pawlowskiQ4YZQ Glad you got it all sorted.
