Assembly3 ConstraintLengthDifference

Description
This tool constrains the length of a 2D line like a non-subdivided wire made with the Draft workbench in relation with a work plane.

It links the length of the 2D line with the length of either another 2D line or a 3D line e.g. a straight edge element or a sketch line.

The length value of the first selected line equals the length value of the second line plus a difference value.
 * (Or the length value of the second selected line equals the length value of the first line minus a difference value.)

Usage

 * 1) Select two lines, of which at least one should be a 2D line.
 * 2) Press the  button.
 * 3) Set the Difference value in the properties panel.
 * 4) Press the  or the  button to recompute
 * (if and  are disabled).
