Moved picked xyz location...

I'm trying to get xyz coordinates from a picked location that has moved...

If I click a pickable mesh and get pickedx pickedy pickedz from the camera pick, then I rotate the model that I clicked, how do I get the new xyz values of the place that I originally clicked?

Hope this makes sense to someone :)

First find the picked coord in models local space and store them :

tformpoint pickedx(), pickedy(), pickedz(), 0 , model
Lpx# = tformedx()
Lpy# = tformedy()
Lpz# = tformedz()

Then after you've rotated the model, get the new picked world coords like so :

tformpoint Lpx, Lpy, Lpz, model, 0
x# = tformedx()
y# = tformedy()
z# = tformedz()
