IE3D geometry building problem!!!

hi,

i have faced a problem in building the geometry of a log-periodic dipole array in IE3D. i could not rotate the antenna boom(of rectangular cross section or may be cylindrical also) along its own axis (boom's axis),so that the elements that r in (+z )direction will be oriented in (-z) direction after the desired operation.

can anybody plz help me out of this problem(otherwise life becomes too tough for me - building the other boom manually from scratch).

eagerly waiting for ur replies.

with best regards
abhi

Hi, Abhi:

Please select all the polygons, and select ADV EDIT->FLIP COORDINATES. Please select Z<->-Z and they will be changed.

Regards.
