Constrain Feature

Used to parametrically locate features within a solid, and to modify previously established constraints settings. Features that may be constrained include holes, bosses, cuts, and protrusions. In the case of cuts, you can constrain the depth of the cut, as well as its location on the face of the solid. Profile features (cuts and protrusions), holes, bosses, and ribs can be constrained to edges, vertices, and faces of a solid.

Features can be located relative to:

Vertices on the solid.
Another (previously placed) feature on the solid.
An edge, plane, or line.

When locating a feature relative to another feature, the direction of the x, y, and z axes of the coordinate system that appears is relative to the direction that the original solid was created.

Setting	Description
Add New Constraints	Lets you set a constraint.
Modify Existing Constraints	Lets you edit the settings for an established constraint.
Icon bar for adding constraints	When Constraint is set to Add, an icon bar lets you choose the type of constraint. Distance — Lets you locate a feature, or a Dimension Driven profile at a specified distance from another feature. Distances may be set between: parallel edges, edge and a vertex, vertex and edge, holes, bosses, ribs, or other combinations of these entities and features. Edges must be parallel, otherwise they cannot be selected. If the edges are not parallel, they must first be constrained with the Parallel constraint. Angle — Lets you specify an angle between linear elements of a profile feature and another feature. Angles are in degrees. Concentric — Makes two point-like entities concentric. This works on vertices of a profile as well as on holes and bosses. Perpendicular — Makes two edges perpendicular. Parallel — Makes two linear edges parallel. Plane Distance — Lets you constrain the plane of a profile or hole/boss to be parallel to and at a distance from a planar face on the solid. Plane Angle — Constrains the plane normal to a profile, hole, boss to be at an angle from the other specified plane. Feature-Feature — Places this feature the specified X, Y, and Z distance from the specified feature location.
Distance	(Distance or Plane Distance constraints only) Lets you define the distance for the constraint.
Angle	(Angle or Plane Angle constraints only) Lets you define the angle for the constraint.
X Delta, Y Delta, Z Delta	(Feature-Feature constraint only) Lets you define the distances along the x, y, and z axes for the constraint.
Equation icons	(Distance and Angle settings only) Located adjacent to the Distance or Angle setting and is enabled prior to accepting the value. Opens a dialog that optionally lets you define each setting with variables. For more information, see Variable Driven Modeling and Constraints.
Treat DD Profiles as Rigid	(Not applicable to Plane Distance, Plane Angle, or Feature-Feature constraints.) If on, dimension driven profiles are treated as rigid profiles, and their dimensions may not be modified to change the shape of the profile and the generated solid. If off, dimension driven profiles may be modified to change their shape, and that of the generated solid.
