15 * \brief Stores data of the Fixed constraint
17 * Fixed constraint may have NULL basic SketchPlugin constraint,
18 * because the Fixed constraint may be temporary for correct moving of objects.
20 * Fixed constraint does not create a constraint, but builds the entities in separate group,
21 * so they will not be moved while resolving the set of constraints.
