Descriere
Constrain Block permite blocarea unui element geometric pe loc cu ajutorul unei singure constrângeri. Scopul său principal este de a lucra cu B-Splines ceea ce poate fi dificil de restrâns complet în alt mod.
It is mainly intended to be used with B-splines, which can be difficult to fully constrain otherwise.
Cum se folosește
Note: pașii 1 și 2 pot fi inversați.
Or press the button first, and then select the elements.
Scripting
Sketch.addConstraint(Sketcher.Constraint('Block', Edge))
The Sketcher scripting page explains the values which can be used for Edge
and contains further examples on how to create constraints from Python scripts.
