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.
The block constraint only affects the freely movable parts of an edge. Blocked edges can have other constraints, and applying addition constraints to a blocked edge can modify it.
Cum se folosește
See also: Drawing aids.
Continue mode
- Selectează un element de constrângere;
- Apăsă butonul
Constrain Block .
Note: pașii 1 și 2 pot fi inversați.
Run-once mode
- Select one or more edges.
- Invoke the tool as explained above, or with the following additional option:
- introduced in version 1.0: Right-click in the 3D view and select the
Constrain block option from the context menu.
- introduced in version 1.0: Right-click in the 3D view and select the
- Depending on the selection one or more constraints are added.
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.
