VW could license the Parasolid kernel 3D constraints/parametrics so that it is a bit easier to create straightforward parametric objects without having to get into Marionette or scripting.

Great suggestion - I'm sure our Roadmapping Room team members would be happy to discuss this with you during our Vectorworks Design Summit Open House day today. Perhaps we'll see you there Art V - everyone welcome. https://www3.vectorworks.net/vectorworks-designsummit-registration

As the previous response suggested, you may need to get into Marionette. I may be oversimplifying your requirement, but in the example you gave, if you select the desired extruded objects, and type in a new extrusion height, the selected objects will all change to the new extrusion depth.
