This type of constraints allows to share points between elements.

When transforming an object that share points with this type of constraint, the transformation applied to the points will be propagated to the associated elements.

Figure 8.3. Connect points

A connect points constraint refers two elements and the indices (index-p1,index-p2) of the shared point for each element.

The constraint is defined when drawing elements with point capture, or when moving and merging points.
