/** \class SketchPlugin_ConstraintDistance
- * \ingroup DataModel
- * \brief Feature for creation of a new constraint which fixes the distance
- * between two other features.
+ * \ingroup Plugins
+ * \brief Feature for creation of a new constraint which defines a distance
+ * between a point and another feature (point, line, plane or face)
*
- * There are allowed several kinds of distances:
- * \li The next constraints use "valA", "ptA" and "entityA" parameters:
- * point-point, point-line, point-plane, point-face;
- * \li The distance between two points projected on a line (or vector)
- * uses "valA", "ptA", "ptB", "entityA";
- * \li The diameter of a circle is defined by "valA" and "entityA";
- * \li The angle between two lines (or vectors) uses "valA", "entityA", "entityB".
- *
- * The default list of attributes contains only CONSTRAINT_ATTR_DISTANCE.
- *
- * \remark As far as the constraint may have different attributes,
- * it is strongly recommended to use setAttibutes() methods
- * instead of direct intialization of the attributes
+ * This constraint has three attributes:
+ * SketchPlugin_Constraint::VALUE(), SketchPlugin_Constraint::ENTITY_A() and SketchPlugin_Constraint::ENTITY_B()
