Hello everyone,

I created a model with a symmetry plane and I would like to project a bunch of fiducials from one side to the other side of this plane symmetrically. Do someone know if it’s possible to do this and if yes how to ?

Thanks a lot in advance !

I think this part of the PseudoLMGenerator module from SlicerMorph will be helpful for you:
