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