Yes JCL you are so right and those facts are stated in the manual on page 82. But with a model that is 50 quants wide the narrow hull is automaticly set for the model. The model only gets no hull asigned if it is smaller than 8 quants. So if the model is 53 quants wide and 30 quants high it should have the narrow hull asigned and should not penetrate an inviisible wall.

If you take the large primitive cube in MED and bring it into WED and do the scaling that I mentioned below you will have the same problem. Both models are larger than 8 quants and therefore have the narrow hull asigned.

Please correct me if I am in error. If I am not in error then please explain in detail why the penetration of an invisible wall with a model that is 53 quants square. The model size measurement is taken directly from the view windows in WED.
