Hello,  
I want to read several geometries for visualisation from a list of .obj files, however their axes are arranged in the wrong order (y,z,x) in my frame of reference.  
**Goal** : _permute dimensions of a mesh._  
The mesh loads OK and can be visualized with Makie,  
After naively attempting permutedims, which did not work, I tried searching for Meshes.jl docs Transformations section. The only applicable one is rotation, but seems like that might be actually computing all those transforms which is undesirable (these a quite large meshes).  
I have a feeling that there should be a straightforward solution that I am missing?

Thanks!

I have a similar issue, but I addressed it by modifying the points before the mesh was constructed.

I think we should be able to rebuild thr faces with the dimensions swapped directly.
