Maximum Aspect Ratio
Maximum Aspect Ratio controls the ratio of the longest side to shortest side in a triangular mesh. It is a type of mesh operation occurring at the object level, and it directly controls the surface representation of the object. Aspect ratio and the shape of the triangulated facet representing the surface of the object, are related. As aspect ratio increases, the triangles become narrower. Setting aspect ratio to 1 does not guarantee equilateral triangles but produces triangles similar to isosceles right-angled triangles.
Default value for Maximum Aspect Ratio setting is recommended. Values in the range of 2 to 20 can produce suitable meshes.
