3.2.1 Selected Model was too small to load

[ryanrybot 0]

So I was just using 3.1 and was merrily slicing away, when I noticed I could download 3.2.1. So I did. Then I tried to load my models into it.

Every single model I try says it's too small to load.

That is all my OBJ files, anyway. STL works fine though. My ancient modeling software doesn't export STL, but OBJ has worked so far without any issues. 

 

Any advice, before I revert back to 3.1?

Could you share log files?

I've had this happen too. Usually, I get two messages: first a mention that the model has been automatically scaled by 100000% and second the "model was too small" message.

 

To be honest, I wasn't sure if these models worked in 3.1 anyway, so what I did as a workaround is to create a small OpenSCAD file to import the model, scale it up and export it again. 

The OpenSCAD code for this is really simple:

scale([1000,1000,1000]) import("model.stl");

I have seen this issue in connection with models scaled in inches. The inch scale is incorrectly interpreted in mm and comes out extremely small.
