Problems with units

I've been drawing a building using solids. I've been sizing the solids using known deminsions of length, width, and height. For example, when I draw a solid vertical beam, I input an x, y, and z value for the start point and then input values for the dimensions of the vertical beam (most of the beams are 4" x 4", so I input 3.5"/12 for length, 3.5"/12 for width, and 14.5 for the height). This has been working until I tried to dimension it today.

When I dimension the objects, my deminsions are displayed in inches. For example, I can draw a 20 ACAD-unit line and when I dimension it, it is displayed as 20", not 20'. I've tried to change the units in ACAD, but nothing seems to work....any help would be appreciated.

Thanks, Ryan

Not sure if (setvar "dimlunit" 4) is what you're after?

I could be wrong - take a note of what it is set at before you do it using:

(getvar "dimlunit")

Ya!..Did you change acad unit in "format" "unit" or dimension style?

Architectural unit for format "unit " always base on 1 units for 1 in!
