Constraint Settings Dialog Box

Geometric Tab

Controls the display of constraint types on constraint bars.

Displayed Constraints

Controls the display of constraint bars or constraint point markers for objects in the drawing editor.

For example, you can hide the display of constraint bars for Horizontal and Vertical constraints.

Select All

Selects the geometric constraint types.

Clear All

Clears the selected geometric constraint types.

Icon Transparency

Sets the transparency level of constraint bars in a drawing.

Display Constraints in the Current Plane Only

Displays constraint bars for geometrically constrained objects only on the current plane.

Dimensional Tab

Sets preferences in behavior when displaying dimensional constraints.

Constraint Format

Specifies the format for the text displayed when dimensional constraints are applied.

Set the name format to display: Name, Value, or Name and Expression.

For example: Width=Length/2

Show Lock Icon for Annotational Constraints

Displays a lock icon against an object that has an annotational constraint applied (DIMCONSTRAINTICON system variable).

Show Hidden Constraints on Selected Objects

Displays dynamic constraints that have been set to hide when selected.

Autoconstrain Tab

Controls the constraints that are applied to a selection set, and the order in which they are applied when using the AUTOCONSTRAIN command.

The following conditions are checked before multiple geometric constraints are applied:

• Are the objects perpendicular or tangential to each other within the tolerances specified in the AutoConstrain tab?
• Do they also intersect within the specified tolerances?

If the first condition is met, then tangent and perpendicular constraints are always applied if the check boxes are cleared.

If you select the additional check boxes, then the distance tolerance is considered for intersecting objects. If the objects do not intersect but the nearest distance between them is within the distance tolerance specified, then the constraint will be applied even if the check boxed are selected.

Autoconstrain Headings

• Applied — Controls the constraints that are applied when applying constraints to multiple objects.
• Constraint — Controls the type of constraint applied to objects.

Note: Drag to change the order.

Constraint Tolerances & Rules

Sets the acceptable tolerance values to determine whether a constraint can be applied.

• Distance — Distance tolerance are applied to coincident, concentric, tangent, and collinear constraints.
• Angle — Angular tolerance are applied to horizontal, vertical, parallel, perpendicular, tangent, and collinear constraints.

Tangent Objects Must Intersect

Specifies that two curves must share a common point (as specified within the distance tolerance) for the tangent constraint to be applied.

Perpendicular Objects Must Intersect

Specifies that lines must intersect or the endpoint of one line must be coincident with the other line or endpoint of the line as specified within the distance tolerance.
