So, when working with Boolean and detailed surfaces I should always make sure my tolerance is at least 10x the smallest detail?

The tolerance should be set at the beginning of the project to 1/10 the size of the smallest detail which will be in the project or the 1/10 the manufacturing tolerance, which ever is smaller. Set the tolerance to an appropriate value at the beginning of the project and then do no change it.

Absolute Tolerance - Set and leave alone, and other good practices

“Absolute tolerance” is the amount of deviation from the “exact” solution Rhino will allow when a curve, edge or surface resulting from various operations cannot be modeled exactly using NURBS. For example the curve resulting from intersecting two non-planar surfaces will ususally not be exacty a NURBS curve. Rhino can create a NURBS curve which approximates the exact curve within almost any desired level of accuracy but as the maximum deviation from the exact curve is reduced the number of con…
