Inputting Property Lines with Arcs

[drubinoff]

Hello,

Thanks everyone for your help.

Here's a question. I'm looking at an existing property survey, prepared by survey engineers. I'd like to replicate the property lines in Revit 2009 using the property lines input spreadsheet feature.

I'm running into a point of confusion with arcs. Revit seems to be asking for directional bearings along with arc length and radius. It seems to want to know, for instance, if the arc bearings are N17deg38'32"E, R=9', L=2.77'. However, the survey gives the arc as delta=17deg38'32", R=9', L2.77'. The "delta" info doesn't mention N or E or S or W.

Any suggestions how I can input the angle info I have? I'm not an expert on reading survey bearings.

Thanks,
Derek

Relatedly, the survey I'm looking at shows arcs has having lengths measured as the actual arc length. The Revit property line tag indicates length but shows it as the CHORD length of the arc. Is there a way to have the Revit tag show the arc length as the arc length and not the chord? Does anyone know which is proper in surveying?

Thanks,
Derek
