Constraints are rules that are applied to 2D geometry. By applying constraints, you can control the location, size, distance, angle, and other parameters of objects in a drawing. As a result, you can identify and maintain specifications in a project.

## What is constraint key in SQL?

## What are the constraints computer?

Constraint programming (CP) is **a paradigm for solving combinatorial problems** that draws on a wide range of techniques from artificial intelligence, computer science, and operations research. In constraint programming, users declaratively state the constraints on the feasible solutions for a set of decision variables.

## What advantages do CAD drawings have over paper sketches?

Some advantages that CAD drawings have over paper sketches include, **being more neat, more precise, quicker to make, more available space to work with**, unlimited resources to work with, easy availability to apply constraints to a sketch, easier sharing of work (ex: email, picasa, etc.).
