If you frequently need to work in more than one unit system or with more than one tolerance, set multiple templates. You can change the default unit system or tolerance by setting up a template. The default unit system is millimeters, and the default tolerance is 0.01 millimeters. Rhino can work in any unit system and with any tolerance.The following three items are a good guide to choosing tolerance.A dialog box will warn you if the units do not match. Importing a model in a format that supports units and tolerance will not adjust Rhino's units or tolerances.It is best to select a tolerance when you start modeling and stick with it.Sets the number of decimal places for the distance display. Sets the display to feet and inches (1'-3'). Sets the distance display for the status bar and distance and length commands. Understanding Tolerances Custom units NameД®nters a scale in units per meter. Two objects will meet an evaluation criterion, such as tangency, when the angle between them is less than the tolerance value. When creating or modifying geometry the angle between two objects will be less than or equal to the tolerance value.

Sets the angle tolerance in some commands use to create, modify, or evaluate geometry. For example, trimming surfaces, doing offsets and Boolean operations usually create approximate geometry. Tolerance in units used when creating new geometry that cannot be absolutely accurate.

Hatch patterns are automatically scaled when units change. 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. Units and tolerances Model unitsД¬ontrols the units used in the model. Layout units properties manage the layout units for the current layout space. Model units properties manage the units settings for the current model space.
