How to change units from mm to feet inches in in AutoCad 2018 Architecture

[leothebuilder · Accepted solution]

It's always best to start with the correct template.

Imperial for inches and feet

Metric for millimeters (or whatever metric unit you need to use)

If you have a metric drawing that used millimeters, copy and past into an imperial (inches and feet template)

and scale the geometry up x 25.4
