Model Precision Question

[tachyon]

Hi all,

Does anyone know if for product design a model is usually drawn with 0-thickness walls, where the thickness of the wall is implied. Or does the model typically have inner and outer wall surfaces for all parts? The problem with the latter is that it obviously takes much more space, however, If you are doing a prototype I would imagine that they require that type of precision. Similarly for the number of faces to approximate a circle, not sure how far to take it. Anyone have any insight into what's "good enough" for designing for this purpose?

Thanks.

It all depends on what you are making the model for - if the the inner walls are going to be seen, then model them otherwise don't bother. As for the circle, try different #'s of segments to see what works best for the current project - there is no correct answer.
