Default Re: How to find "non-manifold" an "open edges" objects

The boolean algorithms seem to have a precision issue with small parts (>1.0) I had troubles for a long time until I scaled up parts to grow substantially. Then the boolean functions leave much less leaky objects. If neccessary, one can scale them down again afterwards. My X-Plane objects were scaled in meters. Scaling them to mm gave much better results on boolean. Cannot fathom why AC3D does not use higher precision for a 64 bit machine. Probably speed is an issue.
