Hi Junko Onuki,

Do you mean Parameters Manager? Or you ask about how to add Constraints in AutoCAD for Mac?

You can add and manage Constraints (Geometric and Dimensional) with menu Tools -> Parametric or with Parametric panel on Tool Sets palette.

Parameters Manager is not available on Mac, you can only use command line version: -PARAMETERS
