How to create arc length dimensions in project by revit api ?

[DinhMinhDuc]

Hi everyone,

This seems to be a basic function of Revit, but I have been searching it for a while and could not find the solution. The Revit help (link below) states NewDimension method can create a linear dimension only.

http://help.autodesk.com/view/RVT/2019/ENU/?guid=Revit_API_Revit_API_Developers_Guide_Revit_Geometri...

Then how do we create non-linear dimension, such as Radial dimension, in project document.

I tried the overloaded NewDimension method:

NewDimension(View view,Line line,ReferenceArray references,DimensionType dimensionType)

I tried to supply a non-linear dimensionType to the method, but it throws exception “the dimension type is a non-linear dimension type”.

I know methods available for creating non-linear dimensions in family document, but how about project document?

What am I missing here?

Thanks

You can use the AngularDimension Class to achieve this :
