Keyshot 7 match perspective bug

[BJT_DAVE]

Never had a problem with this in KS6, but KS7 just locks up on some particular combinations of plane angles. Try 2 point match perspective on the red plane using this as a backplate and let me know if it causes your KS7 to freeze. Im using an iMac if thats of any consequence? If Im correct, then as soon as you align the fourth arrow it will lock up.
