Описание

Constrain Block blocks a geometric element in place with a single constraint.

It is mainly intended to be used with B-Splines, which can be difficult to fully constrain otherwise.

Применение

1. Выберите элемент, степень свободы которого вы хотите ограничить.
2. Нажмите на кнопку Ограничение (Привязка).

Or press the button first, and then select the elements.

Программирование

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.
