A while back we added an enhancement as follows
When we follow the fixed bumper height sometimes it may not work well all-around the vehicle.
So we have to use variable bumper height with a range to pick outer-most point on the model with in that range.
You can set minimum and maximum height to scan the model to pick the outer-most point.
You set that in the Setting window. Unit is feet like you see all the units in the Graphics is Feet.
Go to Settings (the Gearbox at top)
(see update

toggle it on/off to reset/regenerate the points when you change the option in the Settings->Misc tab
