The use of parametric controls for 3D modeling in any software can transform your workflow and give you the flexibility to quickly change the shape of any 3D Object. In Blender, you won't find parametric controls as a default option, but using the right tools, it is possible to add those parametric options.
If you use Drivers, Shape Keys, Hooks, and Custom Properties, you will be able to create parametric controls that will help in architectural modeling projects and also animations. You will be able to add properties to objects that works based on a context.
Do you want to learn how to add parametric controls to objects in Blender 2.8?
With the Blender 2.8 parametric modeling book, you will learn all the steps necessary to create such controls. The book covers all aspects of the process, from planning the controls to the creation of math expressions that will update the shape of 3D models.
You can download the files used in the book to follow each project and also check the final result of all parametric controls.
