Now we’ll get to the real advantages of parametric design. You may write math formulas into your dimensions to drive your design with only a few parameters.
Hidden user variables can control the values of multiple dimensions in the design.

Parametric Design in AutoCAD Part 3: Dynamic, Reference, & Annotation Dimensions

What did you say? You added parametric dimensions to your lines but they won’t show up when you plot. Well, we can fix that.

When a parametric dimension is defined, it is simply a dimension to control geometry. By changing it to an annotational dimension it will display just like a normal dimension.

Parametric Design in AutoCAD Part 2: Dimensional Constraints


After the shape of your design is controled by geometric constraints then it’s size will be defined. dimensional constraints are very similar to the normal AutoCAD dimensions that you are familiar with.

The big difference is dimensional constraints control the geometry but the geometry controls the normal AutoCAD dimensions.
Always remember to define the shape and then the size!
