You'll probably best: - - re-think what you're about to do... maybe geometry is not exactly what you're looking for ;-) - - if you really want to add that 3rd dimension, you'll need to add a "USING ..." to your statement, with some function that takes your X-Y data and adds the Z dimension Best regards, - -- Gunnar "Nick" Bluth RHCE/SCLA Mobil +49 172 8853339 Email: gunnar.bluth@xxxxxxxxxxx _____________________________________________________________ In 1984 mainstream users were choosing VMS over UNIX.
