Would you mind posting the snippet of code you are using to draw the lines?

Also, keep in mind that the positive z-axis of the PPT system depends on the direction that the calibration board was facing when the PPT was last calibrated.

Also, which version of Vizard are you using? The reason I ask is that before version 2.53 there was a bug with On-The-Fly objects where the z-value of a vertex would be negated.
