I have a drawing that was created in engineering units, the architect needs buildings dimensioned to the nearest 1/2". I copied the building footprint, scaled it up a factor of twelve and changed the units to inches, the dimension styles to inches, but i cannot get the dimension tool to show inches (only tenths of foot. Is there an easy solution I'm overlooking?
Another method is to leave your file eng units and make a dimension style that scales the measurement to inches. Simply add a scale factor of 12 to the Primary Units tab of any dimension style. Save the dimstyle to your template and this can be a bit less work.
If you must scale it for the arch then open the file you saved with the scaled bld. Confirm the scale operation with the distance command. If this is off check the Units command. Since you scaled the building up you need Archtectural set. Make sure the dimension style's Unit Format is set to Architectural and the scale factor is 1.
I ditto that
Of course if you opened Acad with an arch dwg and xref in your engineering dwg AutoCAD can also automatically scale the file if insunits and it's associated commands are all set properly. Just one more way to mess things up.
In case John's response was a bit vague, here's an image:
In general, you DO NOT want to work in Architectural units in C3D (in other words, leave all your drawing settings set to Feet/Meters, and DO NOT change the UNITS). Instead, use the trick above to create a Dimstyle that labels what you want.
Of course, this only works with Dimstyles, and we're still missing a way to do something similar with C3D Styles (such as labeling a volume surface in fractions of an inch), but C3D is still a work-in-progress with much left to do...
