I have a question about the application of tolerances.
I am concerned that I might have misunderstood the Rhino document, “Understanding Tolerances”.
Let us say I was modelling a 5.2m long kayak, and that I want the Rhino model to be accurate to within 1mm.
My options are:
a. If I were to work in units of metres, then the absolute tolerance would be set to .001. The boat is 5.2 units.
b. If I were to work in units of centimetres, then the absolute tolerance would be set to .1. The boat is 520 units.
c. If I were to work in units of millimetres, then the absolute tolerance would be set to 1. The boat is 5200 units.
My question is, which unit setting would give be most likely to provide the most consistent modelling performance in my Rhino model, or does it make no difference to whether I work in metres, centimetres or millimetres, because the boat is the same length in the real world?
If I have understood the document correctly, the answer would be c.
