2.4.4 Constraints Toolbox:

Use the Constraints toolbox to define relationships between sketch elements and reference planes.

Fixed: Select a 2D edge or point to prevent it from moving. For an edge, this does not fix the locations of
its endpoints unless "Fix Endpoints" is checked. They can still move along the curve. Endpoints may
also be selected to apply a fixed constraint to them after which they can no longer move.

Horizontal: Select a straight line. The Horizontal constraint forces a selected line to a position parallel
to the X-axis. If an ellipse, or elliptical arc is selected, its major axis will be forced parallel to the X-axis.

Vertical: Select a straight line. The Vertical constraint forces a selected line to a position parallel to the
Y-axis. If you select an ellipse, or elliptical arc, its major axis will be forced parallel to the Y-axis.
Perpendicular: Select two edges as close as possible to the location where they, or their extensions,
would cross. The Perpendicular constraint ensures that, where the two edges cross, they (or if curves,
their tangents) are at 90° to each other.
Tangent: Select two edges as close as possible to the location where they are to be tangent. The
selection location controls which side of a circle the Tangent constraint applies. Also, the tangency can
occur outside of the displayed portion of a curve.
