If the xy ranges dimensions are (for example) 10x10 at 1meter, and the z range is 0-10, then a z-scale of 1 will give a proportionate ("equilateral") view. If the xy scale is 1000x1000 and z range is still 0-10 then a z-scale of 1 will give a very flat looking image. (10 m height range spread over 1000 meter xy "range"). cheers Mike > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Ken Hickey > Sent: Thursday, 21 November 2002 7:35 AM > To: [EMAIL PROTECTED] > Subject: setting Z-scale > > > g'day > > Does anyone know how the Z-scale % values relate to actual z-values in a height layer?
