Description

Constrain distance constrains the length of a line, the perpendicular distance between a point and a line or the distance between two points to have a specified value.

How to use

  1. Pick two points or one line or one point and one line.
  2. Press the Constrain distance button.
  3. A pop up dialog opens to edit or confirm the value. Press OK to validate.

Note: the constraint tool can also be started with no prior selection. To set the perpendicular distance between a point and a line, the point needs to be selected first. By default the command will be in continue mode to create new constraints; press the right mouse button or ESC once to quit the command.

Hint

If applicable please consider using the Horizontal distance or Vertical distance constraints instead. These constraints are more robust and faster to calculate than the here documented length constraint.
