It seems to me that a program that took in base mesh models and then subdivided them as desired before creating variations allowable within the applied tolerances and datum feature references would be a valuable learning tool.
Too often I see requests for "How do I do X" where X is some poorly defined outcome. It seems to me that an interactive tool that allowed users of it to see the direct effect of the choices they made would go a long way, particularly as fewer users seem able to understand simple 3D geometry from 2D drawings.
The current variation generation software is limited to some simple changes, mostly as it feeds non-graphical tolerance stack analysis software. However these fail to capture the really ugly cases that are rolled out to demonstrate limitations/outcomes allowed and give limited insight into how the geometry is affected.
This might also form the basis for variation FEA using these lumpy models and could also be useful in understanding how parts fit together in assemblies.
If the variation generation tools could be appropriately generalized one might also explore variations in interpretations, for example the way the ISO allows position to apply to individual planar surfaces and ASME does not.
Is there likely to be any money to be made with this sort of tool? It seems unlikely.
