Description
Descriere
Aplică un punct pe un alt obiect, cum ar fi o linie, un arc sau o axă de schiță.
Cum se folosește
- Selectați punctul pe care doriți să îl aplicați pe o linie/arc/etc. (Odată selectat punctul devine verde).
- Selectați linia pe care doriți să o atașați la punctul pe care tocmai l-ați selectat(Odată selecatată linia devine verde).
- Apăsați butonul
Constrain point unto object.
- 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
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.
