Best Way to Model an Existing Electrical Wall (Panels on Standalone Frame)?

I’m working on a residential solar project and would like to create a simple SketchUp model (2D or 3D) of an existing electrical wall — basically, a freestanding metal frame with multiple electrical panels and conduit mounted to it. This isn’t part of a building wall — it’s out in the open, kind of like a utility rack or pedestal setup.

I’ve attached a couple of reference photos to show what I mean.

I’m currently using SketchUp Pro without any extensions. Just looking for advice on:

  • The best way to go about modeling something like this from scratch

  • Any good search terms to find similar objects or components in the 3D Warehouse

  • Tips for keeping it clean and simple, since this is just for planning/reference

Would appreciate any guidance or examples if someone’s tackled something similar!
