Thanks to Mr. Raiz for the formula I needed to do the calculation. It is setup to use as a middle segment as I assume that it probably wouldn't be used to start or end. Arbitrary assumption perhaps. The "hard part" (meaning time to work it out is short right now) is getting the arrow to point in the correct direction relative to the arc.

Looks like a pretty neat trick, thanks.

That's awesome, thanks!!!

Great idea, but the download did not work for me, said that "seek failed on c:\........Egress2009.rvt". Working in Revit 2008.
The 2009 version won't work in 2008, I've uploaded a 2008 version. Try again.
David,
Should he be able to just do a formula that determine the tangent angle the arrowhead should be at with regard to the arc? With the trig you're doing already for the arc itself, it should be possible to determine the correct tangent.

got it! thanks!
