"Create a lock constraint on the selected item"

Description

This constraint tool attempts to fully constrain any selected item.

NOTE: It is advised that this tool be exclusively used on points for the time-being:

Owing to the fact that FreeCAD is still under development - this tool exhibits strange behaviour when it attempts to 'lock' anything other than a point. For example (as of V0.12 R4802), when locking a circle by its circumferential line rather than its centre point, a horizontal constraint and a vertical constraint appear in the constraints dialogue, but they are both of value zero and do not appear in the graphics window.

Usage

  1. Firstly it is necessary to highlight an item you wish to constrain. For reasons alluded-to above it is wise to only highlight a point.

  1. Highlighting of a drawing item is achieved by moving the mouse over the item and clicking the left-mouse-button.
  2. A highlighted item will change colour to green.

  1. Once an item is highlighted, left-clicking on the lock constraint serves to lock the highlighted item in-place. This usually manifests as two constraints: a horizontal distance constraint from the drawing axis origin, and a vertical constraint from the drawing axis origin.
