Imperial length format from string

[JamesVan]

Has anyone used the API to display Imperial units (feet and inches) in a form? I'm expanding on the LevelsProperty sample tool, but it's in Metric. Removed the multiplier to get the results to decimal feet, but can't figure out how to parse the string to feet-inch. Tried searching through the help in VisualStudio, but couldn't find anything.

Thanks in advance.

James,

It'd be easier if US converted to metric like the rest of the world Sorry couldn't resist...

The default unit in Revit is imperial. So you don't have to do anything to the values. Go to command.cs. Remove the unit conversion:

double temValue = systemLevel.Elevation * 304.8;

Note you'll have to go through the other files to remove the conversion back to imperial where values are added.ie /304.8.

HTH,

Guy

James,

Here's a couple posts from vbcity on Feet and Inches conversions. Not too difficult.

Thanks guys. I'll work on the feet-inch conversion shortly, but I'd like to include an IF statement for DisplayUnits...(If metric, multiply by 304.8 etc.). Do you have an example of that?

James,

I take it you mean automatically adjust for metric or imperial projects? The easiest way to do that is probably to use the SetValueString and AsValueString methods of the parameter class. These automatically take into account the display unit of the parameter.

Does anyone know if it is possible to use Metric and Imperial Units in the same tag? My company has a job where we need to show Metric, but we'd like to keep Imperial. Thanks.
