FIXED Odd problem with duplication.

[Foz]

Anyone come across this problem before?

I have created a model and uploaded it to Shapeways to check it passes the Auto Checks, which it does for FUD.
Then duplicate the model (in three different pieces of software just to make sure) and the x2 fails with thin walls.
Never had an issue before. I do have a call in to their support too.

That's new to me; and I have a lot of designs with duplicate models in one Shapeways package (all the 1/288 and smaller planes). Does the thin-wall visualization show anything useful?

[Foz]

The two planes were showing differences. I didn't realise though, that Meshmixer or Blender can introduce errors when duplicating. So I do the copy, then run it through error checking again. That seems to have solved the issues for the moment.
