Description
Descriere
Aplică un punct pe un alt obiect, cum ar fi o linie, un arc sau o axă de schiță.
introduced in 1.0: This tool is replaced by the Sketcher ConstrainCoincidentUnified tool if the Unify coincident and point-on-object constraints option is selected in the preferences.
Cum se folosește
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- Press the
Point-On-Object Constraint button.
- Select the Sketch → Constraints →
Point-On-Object Constraint option from the menu.
- Use the keyboard shortcut: O.
- Press the
- The cursor changes to a cross with the tool icon.
- Select a single point and a single edge (in any order).
- A constraint is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Run-once mode
- Do one of the following:
- Select a single point and a single edge (in any order).
- Select several points and a single edge (idem).
- Select a single point and several edges (idem).
- Invoke the tool as described above, or with the following additional option:
- Right-click in the Elements section of the Sketcher Dialog and select the
Point-On-Object Constraint option from the context menu.
- Right-click in the Elements section of the Sketcher Dialog and select the
- Depending on the selection one or more constraints are added.
Scripting
Script
Constrângerea poate fi creată din macrocomenzi și din consola Python folosind următoarea comandă:
Sketch.addConstraint(Sketcher.Constraint('PointOnObject',LineMoving,PointOfLineMoving,LineFixed))
- Sketch este un obiect sketch
- LineMoving este numărul care desemnează linia, care conține punctul care trebuie mutat pe LineFixed (Linia care este fixă)
- PointOfLineMoving este numărul vârfului liniei LineMoving, care trebuie mutat pe LineFixed
- LinedFixed este numărul liniei care trebuie aplicată pe punctul PointOfLineMoving
Pentru a identifica numărul care are indică liniile și punctele? Vă rog să vă referinți la parte de script a Sketcher ConstrainCoincident.
