Edit Constraint

Dialog Box Options

Value
Defines the value of the distance, angle, or radius, depending on which constraint type you are defining. This is a numerical value and it must be greater than 0. You can also enter the value as a numeric calculation, such as 360/8. The calculations available are the same as those in the Formula field.
Formula
Defines a variable or an expression for a distance, angle, or radius. Define the Formula Field
Drives geometry
When Drives geometry is selected, the constraint will function as a geometric constraint that can edit geometry. You can make a constraint a driven dimension by removing the selection Drives geometry. A driven dimension can not edit geometry, but variables or expressions can be assigned for it in the Formula field.
Note: Driven dimensions defined in a 3D sketch can be used to create customer deliveries with parametric models (requires Vertex Flow). Read more: Vertex Flow Product Documentation
Active
When Active is selected, the constraint is enabled. You can disable the constraint by removing the selection Active. When a constraint is disabled, you can, for example, drag a line fixed with the constraint in a sketch. You can re-enable the constraint by selecting Active again, and the line that was dragged will return to the position defined by the constraint, for example.
You can enable and disable constraints also by selecting a constraint from the list and selecting the context-sensitive function Disable or Enable.
Elements
Defines the elements of the constraint. You can change, add or delete elements.
Note: The program will not prevent you from selecting unfit elements. Make sure, that the constraint can be solved for the selected elements.
