Description
Popis
Použití
- Select a point and an edge in any order.
- There are several ways to invoke the command:
- Press the
Constrain point onto object button in the toolbar.
- Use the O keyboard shortcut.
- Use the Sketch → Sketcher constraints →
Constrain point onto object entry in the top menu.
- Press the
Scripting
The constraint can be created from macros and from the Python console by using the following command:
Sketch.addConstraint(Sketcher.Constraint('PointOnObject',LineMoving,PointOfLineMoving,LineFixed))
Sketch
is a sketch object.LineMoving
is the number that designates the line, which contains the point that has to be moved onto theLineFixed
(the line which is fixed).PointOfLineMoving
is the number of the vertex of lineLineMoving
, that has to be moved onto theLineFixed
.LinedFixed
is the number of the line to be affixed onto the pointPointOfLineMoving
.
The Sketcher scripting page explains how to identify the numbers that designate lines and points.
