Coincident: Select two points, two edges, or a point and an edge as near as possible to the location you
want them to be coincident. The coincident location can be outside the displayed portion of either
edge.
Midpoint: Select a point and a line. The Midpoint constraint forces the point to be on the line an equal
distance from the line endpoints. You can preselect a series of point-line pairs before selecting this
function.
Symmetry: First select a line to be the symmetry axis, then a pair of points or edges (of the same type)
to be symmetric about the axis. If you want the endpoints of the curves to also be symmetric, you need
to add symmetry constraints to them as well.

Parallel: The default right mouse button option, Select pairs, allows you to select a pair of 2D straight
edges, such as lines. The Parallel constraint forces the selected lines or major axes for ellipses and
elliptical arcs to be parallel.

Concentric: The default right mouse button option, Select pairs, allows you to select two points,
circles, circular arcs, ellipses, or elliptical arcs. The Concentric constraint will force selected points, or
centers to be at the same location.
