Constraint (computer-aided design)
A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon Geometry, geometric properties of an entity of a design model (i.e. sketch) that maintains its structure as the model is ...
, a demarcation of geometrical characteristics between two or more entities or solid modeling bodies
*
Constraint (mathematics)
In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of c ...

Constraint (information theory)
