Hi Prof,

How can i transform a 3D cylinder using
[code]"z:"+cta [/code]
and
[code]y:90d[/code]

each works on its own but i can't figure out how to add both.
for example i tried but it doesn't work
[code]"y:90d & "z:"+cta"[/code]

i want a rotating cylinder with both transformation to achieve the look of a cylinder [img]http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=dlattach;topic=1293.0;attach=1453;image[/img]
