BIM is all about "I". What If?

You've been asked for the velocity and the throwing angle of a bird with anger management issues to hit the wall on the second level?

Well.. Fear no more!
The velocity and the throwing angle of a bird with anger management issues calculator family is at your service!
(Call this one useless! I dare you! :)

Angry.rfa (Revit 2015)

Angry family has 3 data entry parameters, an informing and a visibility parameter.

θo = Throwing angle
Vo = Throwing speed
t = Estimated impact time
tflight = Total flight time
cheat = Flight path visibility

And this is how it looks when the cheat parameter's checked.
I warn you! It's not as easy as it looks to hit something, especially in complex BIM models!
