Whenever I import an stl file into s3d that is less than 10mm across it automatically makes it ridiculously large.
It's not misreading the size of the object and they are all in millimetres. It's actually simply scaling it up to 2540 % of the original file.
Why that partiular number - I don't know. But it's the same every time.
When i change the scaling back to 100% - everything is the right size.
It's weird, it's annoying and it's definitely a bug (undocumented user feature)
So I'm reporting it
