What’s the math? Can’t you just write the formula to calculate linear meters by extrapolating values from other fields? Or, am I misunderstanding the challenge?
It's primary school geometry. Below is an example of a simple family.
r = radius of centerline of revolve
Angle = revolve angle
Length (shared parameter) = 2 * 3.1416 * r * Angle / 360
Wouldn't "3.1416" = "pi()"?
e.g.: 2 * pi() * r * Angle / 360
Revit school vs primary school.
@bechiri.2010: Go with me here...do you have any fields your schedule that report values that you could use in a custom formula calculation? I believe that is the larger point that Toan is making. If you know the math, then you can write the formula. How do you compute it manually?
@ToanDN, that's why I keep Munkholm's cheat-sheet pinned above all my workstations...because I forget sometimes too! HA!
