Flip Shape On Generator

[Hitsu San]

Hi there, i was wondering if you could make just one side of a rail track and have it merged mirrored in the Generator so that you only have to modify the one side instead of having to do a non mirrored shape for a mirrored result?

Hi,
I can't think of anything that would do the flipping in the Generator. Maybe having a negative scaling in the TRS Shape module or the Shape Extrusion module? I can't test this myself for the moment, my computer is out of service right now.
If no flipping is possible, the solution I see would to
1- duplicate the shape
2- flip the duplicated shape using the Flip tool
3- move the CPs of the duplicated shape into the original shape
Did this help?
