Scaling and Sizing

Hey All,

I am just getting into SWIFT 3D, and I want to know how to properly setup a to-scale model.

This model I want to create is going to be 85" Hight x 60" Wide x 29" Deep.

I want to know how to correctly set it up,

I dont know if this is right but I tried setting up a canvas at 1000 x 700px
Key I want 10px = 1"


I can get this far, but when I draw a box, I dont know what settings to put for the scaling and sizing. I just want the elements drawn to be to scale so that when I draw out this model, the ratios are correct
