Is there a way, both on a drawing and in a feature sketch, to dimension a circumference or a perimeter? In this case, it is actually a driven elliptical path.

Thinking there must be a way to call this value out.

Thanks.

Thanks for the replies.

I was unable to get "Path Length Dimension" to work on an ellipse, or anything for that matter.

I'll keep trying.

The Path Dimension function only works on multiple sketch entities. If you'll use the Split Entities tool (Tools > Sketch Tools > Split Entities) to split the ellipse into two partial ellipses then it will work.

As far as I know there is no direct way to dimension a singular closed circle or ellipse for perimeter or circumference. A workaround is if it were of two or more segments then path length as Glenn Schroeder shared.

Edit: The answer depends. If there are multiple entities then use the Path Length Dimension function. If it's a single arc then click on each end and then the arc itself while the standard Smart Dimension tool is active. I haven't figured out how to get the length of a partial ellipse.

Second edit: As soon as I typed this and clicked on "Save Reply" it occurred to me that there is a way to get the length of a partial ellipse. Use the "Split Entities" tool to break it up into two entities, then Path Length will work.
