How to quickly build a box with a given number of isocurve?

I don’t want to use the loft.
Or add isocurves to an existing surface.


For use in T-Spline, comand Pull Control Points.

Hello - MeshBox and in V7 SubDBox, may be the thing you are after?

Thanks, but I don’t want to use version 7.
I will try to create a box, then Explode, Rebuild and Join. But it takes a long time.
