Dimension arc length in Revit API

[pasgatto]

Hi to all,

I tried to search API documentation, this forum, web etc.. While i've not problem with linear dimensions  i didnt find anything about dimensioning arc length (i'm using C# language) in project environment.

I'd like to dimension arc detail lines in the current project view. 

I tried the  NewArcLengthDimension Method (View, Arc, Reference, Reference, Reference)  as reported in API documentation:

https://www.revitapidocs.com/2015/a33279db-ba00-7cb7-1cea-9f4eac33b747.htm

but it seems to work only in the family editor, not in project environment ..

Perhaps is not possible to do by API?

Thank you to anybody will help me

Hi @pasgatto ,

Looks like it is not possible to create ArcLength Dimension in project document using Revit API.
