arc length

[JimB]

Is there any way of measuring arc length in Visio short of knowing the
radius? Is there any way of determining radius?

I don't have my math book handy but I think if you know the straight length
from point to point and the height from straight to curve you can compute arc
length from formula. Find a good geometry book or search web via google for
arc length calculation geometry etc.
I don't know of anything direct in Visio...unless buried in developer tools.

Programmatically you can call the Shape.LengthIU method to find the length
of a curve. There is not an equivalent ShapeSheet function unfortunately.
