Steel beam length

When placing a steel beam object with an inclination of say 45 degrees, AC measures the length in the axis of the object.
This is not useful for construction purposes as the overall length of the beam is longer.
Is there a way to get the max length of the object?

You can modify the script to get the proper length:

basically on one end: X= W/(tan(alpha))
where X is the lenght addition
W is the height of the beam
alpha would be the resulting angle - but it is not the angle of the beam - but also relays on the cut-off angles of the end(s)

the problem with tan is that You should filter out 90 and 270 angles.
You could also develop formula with SIN and COS to get the result
If I am not mistaken X= cos(alpha)*W/(sin(alpha))
