Arc Length of a Sweep Blend

[redmondb024]

Hello! I have been trying to lay a dimension line for the arc length of a sweep blend I made. It allows me to create an arc length dimension for a normal sweep, but it won't let me for the sweep blend element. I am thinking maybe it has to do with the fact that profiles 1 and 2 don't sit directly on the sketch path like my sweep does? 

Any suggestions or advice would be greatly appreciated!

If the profiles are not on the arc path then the swept blend edge is no longer an arc, but an partial ellipse or a spline curve.  Therefore you cannot place arc length dimension.

Thank you! that clears things up for me for sure. Do you have any recommendations on how to measure the length of it then?

You can get there in an Adaptive Template with a Spline through Points.

You can create a mass in place with ref points along the edge of the swept blend, a spline thru points, and you can have the length.
