- Select the point you want to affix onto a line/arc/etc. (Result: Once selected the point will become green).
- Select the line you want affixed onto the point you have just selected (Result: Once selected the line becomes green).
- Invoke the Constrain point onto object tool using several methods:
- Press the Point on object button in the toolbar.
- Use the Shift + O keyboard shortcut.
- Use the Sketch → Sketcher constraints → Constrain point onto object entry in the top menu.
Note: The order you select the line and point does not matter. The point will always move to line. In other words, the line remains fixed.
The constraint can be created from macros and from the python console by using the following command:
Sketch is a sketch object.
LineMoving is the number that designates the line, which contains the point that has to be moved onto the
LineFixed (the line which is fixed).
PointOfLineMoving is the number of the vertex of line
LineMoving, that has to be moved onto the
LinedFixed is the number of the line to be affixed onto the point
How to identify the number that designates lines and points? Please refer to the scripting section of Sketcher ConstrainCoincident.
