Setting equal curve lengths

Hello. I'd like to set the curve length of an arc equal to a straight line in a sketch, but can't seem to do it with the equality constraint. Is there a simple way to apply this relationship so that it updates automatically as one of the curves is modified? Thanks.

Effective but esoteric. Is that why you have the 'visit Onshape' tab so we can get an explanation?
The challenge is that 'length' and 'arc length' are two different things.
If i said, make this line and this arc 'equal' - what am i setting to be equal? The length? The Radius?
This solution uses a custom feature that allows me to measure something and assign the measured value to a variable. Once a variable exists, i can use it in any other sketch or feature (but not the same one).
By sharing the document, the user now has access to the custom feature
Note: you still can't dimension the length of a spline, conic or path in sketcher, just individual arcs and lines. See this improvement ticket.
