I have a series of curves which are entirely ‘flat’ … i.e. they have x,y co-ordinates, but are aligned to zero in the z-plane
When I select them using the applycrv command I just get an error ‘curves are not in world XY plane’… what does that mean in this context ?
Can you share the geometry?
Yes, of course

your curves are in Y-Z Plane, not in X-Y Plane.
use
_rotate3d
or
_orient3pt
or other transformation to fix it.
to check use
_boundingBox (World)
to be sure the curves are planar
_projectToCPlane
x will become u
y will become v
_dir will show u-v of the surface
hope this helps - kind regards -tom
yes sorry i rotated them 90 degrees…
but even orientated as you show I could not get applycrv to run… i just got the error about world axes
Try running _CPlane _World _Top _ProjectToCPlane _Pause _Yes on the curves.
@Measure shows that your (@ambrose_bill ) setup is wrong
@tom_p “my” screenshot shows a setup after transformation that works.
attached a file where _applyCrv does the job.

also notice my edits in the initial post:
Brilliant Thank you. Very clever solution.
Thank you also @Tom_P for your explanations.
Not sure I completely understand… I even ran bounding box and it looked like this (but didn’t work)
…so there don’t seem to be any visual cues to explain the phenomena…(i.e. nothing on screen to tell you why it is wrong, or when it is fixed)
Appreciate your simple workaround though very cool
