What length in pixels does a Wings3D unit of measurement equate to?

[oort]

Micheus,
Thanks for the updated file.

Since all other slicers can use a scale of 1STL Unit = 1mm, I wonder if Up Studio actually needs to be scaled to 0.0393701???

I installed Up Studio. Unfortunately it seems that if you do not have a 3d printer connected you cannot import files and look at them. Maybe I did something wrong but I don't think so.

Maybe the only thing needed for the Wings3D plugin is to be able to choose the units and object scale???

Thanks,
oort
