Hi Jason,
If you want to have a good looking technical view with dimensions I recommend the scaffolding to be designed / drawn up in cad and than rendered out. Reason being that the dimensions proportions and look will be precise, you can use the image for marketing and/or demonstration purposes and you have a building block you can send out to your clients if need be.
I work a lot with drawing up scaffolding, building libraries and designing structures with scaffolding for the entertainment Industry. So I have a lot of experience in that area.
Kind Regards,
Demko Giorgio ter Bals
