# CurveLength text field formula new options

So now CurveLength text field formula can display surface edge lengths like so:

but can it do the same for polycurve segments? It seems to accept the segment
(picked by Ctrl + Shift + LMB), but it shows 0 length…

Hello - yeah, I see that - I suppose it ought to work properly on sub curves or not at all. The formulas look at object ids, which are top level things, so for now, using `SubCrv` or`ExtractSubCrv`with Copy=Yes, then dimension that…

-Pascal

This should be possible. Added to thr wishlist at
