2D

	Auto Constrain Identifies the existing constraints and relationships implied by the construction of the geometry, and highlights them.
	Parallel Used to apply parallel constraint between two linear segments or ellipses.
	Perpendicular Used to apply perpendicular constraint between two linear segments or entities.
	Coincident Used to constrain linear or circular segments or vertices in such a way that they pass through a single point.
	Tangent Used to constrain curves to be tangent to other curves or linear segments.
	Fixed Fixes the end points and direction of a linear segment or the center point of a circular element to its current position in the plane.
	Concentric Used to constrain arcs, circles, ellipses, or vertices to have the same center point.
	Equal Used to constrain the length of linear segments or entities and radii of circular segments or entities to resize to the same measurement.
	Show DOF Used to display the number of linear and rotary movements, a profile element is free to take, along x, y or z axis.
	Remove All Used to remove all geometric and dimensional constraints from a selected element.
	Auto Constraint Settings Used to control the settings for Auto Constrain tool.

Dimensional

	By Element Used to add a dimension to a profile element.
	Distance Used to constrain the distance between two profile elements or between the two end points of a profile to a set value.
	Angle Used to constrain the angle between two segments to a fixed value.
	Equal Distance Used to make the perpendicular distance between three or more co-planar profile segments equal.
	Area Used to constrain the area of a geometry.
	Perimeter Used to constrain the perimeter of a geometry.
	Variables Used to create and manage variables and variations for the active model.

3D

	Parallel Used to apply parallel constraint between the edges or faces of two 3D elements.
	Perpendicular Used to apply perpendicular constraint between the edges or faces of two 3D elements.
	Coincident Used to constrain the faces, edges or vertices of 3D elements to be coincident.
	Tangent Used to constrain a circular 3D element to be tangent to other circular or rectangular 3D elements.
	Fixed Used to fix the linear and rotary movement of a 3D element.
	Concentric Used to constrain the faces, edges, or vertices of two 3D elements to be concentric.
	3D Dimension Used to constrain the distance between the vertices, edges, or faces of one 3D element to another 3D element's vertices, edges, or faces.
	Manipulate 3D Constraint Used to modify the constrained vertices, edges, or faces of a 3D element.
	3D Angle Constraint Used to apply angular constraint between two 3D elements.
