It looks like the Z-Suite V1.8.2 program is modifying the model that was loaded as a .STL file. I hope that the two figures that I attached are visible.
The first figure is what is loaded into the Z-Suite program and the second one is the result of clicking > Print.
The second figure looks shallow compare to the original one. The cross-section of the original model is a semi-circle.
I'll appreciate if someone can tell what's going on. The .stl file in english units is also attached. Thanks.4176
