Can someone please clarify what degree of precision can be “guaranteed”, and when tolerances come into play?
What is absolute tolerance / relative tolerance, angular tolerance, how do these relate to floating point accuracy issues, and so on?
If I model something far away from the origin, in inches or feet, rotate it to some 100th of a degree, extrudes, trim, etc… then I orient this closer to the origin and Make2d, should I expect that the output is going to get progressively worse with each operation? Then if I’m using the make2d output for creating 2d drawings and dimensions… how close are the tolerances? Can we be assured that the output is within .01", ready for fabrication after all these? I’m finding that this is a bit confusing, especially when boolean operations don’t work on simple shapes.
Any enlightenment you guys are willing to offer would be much appreciated.
