Q. Herringbone and Helix Gears with Sweep.

Bricscad V19. I'm a padawan learner.
One of my portfolio projects is helix gears. Relatively simple, create a gear profile, then sweep it around
a center line. My challenge is a herringbone/double helix gear where one side goes in one direction and
the other the opposite direction. AC has an CW/CCW option in sweep. Bricscad V19 does not.

What's the trick to sweeping in the opposite direction?

thanks

    Because I'm a lazy old guy, I'd do one half of the gear and then 3D mirror that half to complete the herringbone pattern.

    As Buckaroo Banazi once said:

    Thanks, that was almost 2 easy.
