How did you do?

There is a "bug" in the current version that is prone to have this error when 45 rotation is used. It doesn't always fail.

I'm hoping to corrected and updated version soon.

Just be aware that gluing isn't a problem to be fixed but a useful feature. It allows you to easily place components on different faces at various angles and move with those faces.

The problem was resolved by installing su 2014. 😍
