I'm not sure which plane you want to mirror your curve around, but I can see that your curve is being mirrored about the default plane in the mirror component. If you wanted to mirror about your line "R2" here is an example of that:
http://groups.google.com/group/grasshopper3d/web/MirrorCurve.jpg It uses the "Plane from X and Y axes", where one axis is your R2 line, and the other is a unit Z vector, and the origin of the plane was left at the default (0,0,0). Does that help? -Chris On Jan 6, 7:34 am, fivenet <[email protected]> wrote: > the profile that i try to > mirror.http://grasshopper3d.googlegroups.com/web/profile+study.ghx?gda=DQih-... > Five
