Michael, thanks for the tip with the autodesk tutorials.
Kavan, i find the idea of using 3ds max for simulations, as you said for eg. watershed calculations, very interesting. i hadn’t thought you could enter the necessary data into 3dsmax for the programme to calculate and simulate these events. that’s very intriguing, although my laptop would certainly not cope.
would be interested to know more about it. could you post a link where to find more info on this? THANX
