As the subject states, Inventor crashes if an attempt is made to evaluate unitize(-Point(0,0,0))
This can easily happen if one is subtracting points to get a vector to unitize and forgets the first point, or accidentally forgets to paste a value back in etc.
Can others please test this on your machine and let me know if you run into the same issue or if this is only happening on the version I'm running?
my installed version: 4.3.523
In ETO 2012 SP1 O get the following:
> Intent unitize(-point(0,0,0))
