When you change from one units system to another, Rhino asks if you want to have the geometry automatically scaled to match the unit change.

Hatch patterns are automatically scaled when units change.

絕對公差

Tolerance in units used when creating new geometry that cannot be absolutely accurate. For example, trimming surfaces, doing offsets and Boolean operations usually create approximate geometry.

相對公差

Sets the relative tolerance used in some commands. If, in those commands, the relative tolerance is smaller than the absolute tolerance setting, the relative tolerance is used instead.

角度公差

Sets the angle tolerance in some commands use to create, modify, or evaluate geometry.

When creating or modifying geometry the angle between two objects will be less than or equal to the tolerance value.

Two objects will meet an evaluation criterion, such as tangency, when the angle between them is less than the tolerance value.

附註

• It is best to select a tolerance when you start modeling and stick with it.
• Importing a model in a format that supports units and tolerance will not adjust Rhino's units or tolerances. A dialog box will warn you if the units do not match.
• The following three items are a good guide to choosing tolerance.
• Rhino can work in any unit system and with any tolerance. The default unit system is millimeters, and the default tolerance is 0.01 millimeters. You can change the default unit system or tolerance by setting up a template. If you frequently need to work in more than one unit system or with more than one tolerance, set multiple templates.
• In general, Rhino works best if you choose a unit system whose absolute tolerance is around 0.01 to 0.001, the "size" of a small feature (like a tiny fillet or small curve offset distance) is >= 10 x tolerance, and the "size" of the model is <= 100000.
• Using an absolute tolerance that is smaller than 0.0001 will noticeably slow some intersection and fitting processes.
