This sounds like whining, even as I read it back to myself, but the reality is that we seem to be wasting a LOT of time.
Is solid modeling so difficult for some applications/geometries?
Are surface models easier to use for fabrication or assemblies?
I seldom, if ever, use surfaces, so I really don't know.
I do know that I spend a good amount of time fiddling with surface models that have gaps, hanging zero-thickness edges, overlapping surfaces, self-intersecting geometry, and other anomalies that render them nearly useless for manufacturing.
Am I just an unlucky recipient of bad models, or is this truly a pervasive issue?
