When we constrain, we fix geometry and relate its orientation and position to other geometry in a particular work plane. This ensures appropriate behavior when geometry resizes. Certain constraints are automatically applied.
We can also apply constraints manually when we create custom profiles. The following constraints are available:
Tangent - Maintains tangency between two arcs, or an arc and a line.
Parallel - Forces two lines to remain parallel.
Perpendicular - Forces two lines to remain perpendicular
Concentric - Maintains location of a point at the center of an arc or circle. Will also force arcs and circles to maintain the same center point.
Coincident - Forces two types of geometry to occupy the same position.
Equal Distance - Maintains an equal distance between three points.
Equal Radius - Maintains an equal radius between arcs and circles.
Midpoint - Forces the position of a point to be equidistant between two lines.
Symmetric - Maintains symmetry about a line.
Normal - Forces a curve to intersect a line or curve where its tangent is perpendicular.
