Modelisation recommendations

A few recommendation when using CAD -> convert program(ex:stl2dat) to modelise parts:


Example:

Part with a cylinder not multiple of 22.5

Part modified to use a cylinder of 90

Resulting tessalation. Notice the odd number of facets of the cylinder.

Resulting tessalation. The cylinder can be modelised with a standard primitive.

 

 

Sketch of the part

Intersection of two cylinders.

Cylinder made with polygons instead of circles.

Resulting tessalation. Notice the number of unwanted triangles.

Resulting tessalation. The facets defining the cylinder are exactly matching the polygons.
