Model units properties manage the units settings for the current model space.

Layout units properties manage the layout units for the current layout space.

Units and tolerances

Model units

Controls the units used in the model.

Layout units

Controls the units used in the layouts.

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.

Absolute tolerance

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.

Angle tolerance

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.

Understanding Tolerances

Custom units

Name

The unit name.

Units per meter

Enters a scale in units per meter.

Distance display

Sets the distance display for the status bar and distance and length commands.

Decimal

Sets the display to decimal (1.25).

Fractional

Sets the display to fractional (1-1/4).

Feet & Inches

Sets the display to feet and inches (1'-3").

Display precision

Sets the number of decimal places for the distance display.

Note

Distance units

Use any of the Rhino unit measurements including fractions. You can mix fractional and decimal input.

Angle units

Use any of the Rhino angle unit measurements including fractions. You can mix input types.

The direction for 0 degrees is 3 o'clock. Positive angular measurement is counterclockwise.

Decimal Degrees

The "°" symbol can be used, but it is easier to just type d.
