Need a Video demo for parametric desk layout

Please would someone have a good video demo about using the parametric feature to layout a desk in an office space?
For example, I have an office space of 20m2 and use parameters to automatically place a desk with a certain spacing between each row.
Something similar to that but with desks: Modeling in SketchUp WITH NODES! Parametric Modeling for SketchUp Extension - YouTube


This can be done easier with native tools. I have tried that extension, only to find it is rough around the edges. Make your desk a group, then use the copy and array tools.
