Because of increased accuracy in the new solid modeler, AME models may

look slightly different after conversion. This difference is noticeable where

the previous version of the solid modeler identified the surfaces of two different

shapes as so close as to be considered in the same plane. The new solid

modeler's finer tolerance may interpret these surfaces as being slightly offset.

This phenomenon is most apparent with aligned features such as fillets,

chamfers, and through-holes.

Holes might become blind holes when the new modeler, with its much finer

approximation capability, interprets what was once a through-hole as being

slightly less wide than the solid. Typically, the length of the remaining solid

material is the difference between the tolerance of the previous modeler and

that of the new modeler.

Likewise, updated fillets or chamfers can occasionally be placed slightly below

the surface, creating a hole through the solid, leaving the original shape

unaltered. Also, drawing fillets or chamfers slightly above the original surface

creates an uneven transition between the solid and the fillet or chamfer.
