Diameter

Diameter

The Diameter command reports the diameter of a curve at a specified point.

Steps

1. Move the mouse cursor along a curve.

   The Units pane on the status bar reports the diameter of the curve at the current cursor location.

2. Pick a point on the curve.

   The diameter and radius are reported to the command line.

   If the diameter and radius return "infinite", the curve is linear (no curvature) at the picked location, or has the shape of a line or a polyline.

Command-line options

SelectCurve: Limit the selection to a specified curve. Press Enter to select any curve.

MarkDiameter: Places a point object at the evaluated point on a curve and creates a curvature circle through that point.

Units: Set the units for the length display. This option is only available if no objects are selected.

SubCrv: Type subcrv to select part of a curve as input.
