ImportMesh Orientation


I’m trying to understand how I should import stl files to get them oriented as intended. As is they always end up “mirrored” (Y and Z swapped).

Importing a .glb behaves as expected, but when importing an .stl, the Y and Z axes are swapped. This is the case for both left and right handed coordinate systems. I could manually swap all the YZ points, but I really feel like I’m missing something.

I created this playground that imports the same coordinate axes mesh from a glb, and an stl.

Any help/insight would be appreciated!


Playground FYI:
At the top of the file: scene.useRightHandedSystem = true;

I added blocks to my imported axes so they could still be distinguished without color. X: 1 block, Y: 2 blocks, Z: 3 blocks

Hi @Crispy and welcome to the forum. There is an extensive discussion on this here Permanently change set of axes which you might be interested in.

Thank you, that’s exactly it!
I’m glad it’s not just me :slight_smile:
