Length

The Length command reports the length of curves or edges.

Supported input
Curves Mesh edges (select with Ctrl+Shift)

When multiple objects are selected, the accumulated length displays in the command history.
Cumulative length is calculated from all curves in a group unless using Ctrl+Shift+click to select group members separately.

Group members that are hidden or on hidden layers will not be calculated.

Command-line options

Units

Set the units for the length display.

SubCrv

Type subcrv to select part of a curve as input.

Hidden command-line option

SelChain

Selects connected curves or edges based on continuity conditions.

Command-lines options are only available with post-selection.

Nesting the Length, Radius, and Distance commands

The Length, Radius, and Distance commands are nestable. This means that if Rhino is asking for a distance in a command, you can use these commands to measure another object or distance and the resulting value will be feed to the command as if you had typed the number.

Example using Offset

Start the OffsetSrf command.
At the prompt for the offset distance, type Length, Radius, or Distance, and press Enter.
Select a curve.
The offset distance will be set to that value.

Example using Fillet

Start the Fillet command.
At the prompt for the radius, type Length, Radius, or Distance, and press Enter.
Select a curve.
The fillet radius will be set to that value.
