  2. Use mirror tool, swap left and right. (Red allow) 20220627111934
  3. Use "select face to align to build plate" tool, click that surface that have "Z".

Actual results

Cura rotates the "Z" surface (clicked surface) to top. (In this case,"Nothing changed") 20220627111934

Expected results

Cura rotates the "Z" surface (clicked surface) to bottom (touch to build plate) 20220627113937

Additional information & file uploads

If I click "X" surface, cura moved the surface to top too. 20220627113617

The "select face to align to build plate" tool without Mirror tool works as intended.

I guess the mirror tool confused the "select face to align to build plate" tool.

Hello, this one has come up before. Not sure how it sneaked back in. We will discuss this issue.

Thanks for informing us

For me this issue doesn't happen. After mirroring, clicking on a surface still moves the surface facing down to the build plate.

We are thinking that this might be different per computer. The "lay flat on surface" function makes a render of the scene's normal vectors and rotates the object based on the normal vector of the pixel you click on. Maybe your GPU renders the normal vectors differently and that's what's causing the issue.

Because it's hard to reproduce and seems to be rare in the field, we've decided to defer this issue for now. If it starts becoming more frequent we can reconsider the priority.

I can reproduce.

1-axis inversion causes the selection surface to face up With 2-axis inversion, the selected surface faces down
