i've created some basic dynamic block in the past but i'm a bit out of my league with this one. I need a plan view block of a Self-Supporting cell tower that will allow me to choose the face width and also allow me to choose the diameter of the concrete caissons/footers. I've attached a dwg with the SST that has a 35' face and 8' dia caissons. Any tips/input on how i can add those options would be greatly appreciated. I would be happy to post the finished block for all to use.
