create level curves given two polylinese

[GmbArk]

hi, can you tell me if there is a lisp that allows, in 2d, to automatically create a x number of level curves (polyline), given the initial curve and the final curve?
e.g. I have the curves in polylinee closed every meter, and I need to have the curves every 20 cm, without crazy to redesign them all.
Thank you.

2d?
but aren't the level curves high?

 

[GmbArk]

No, they're flat, xkè I'm working in 2d.
I searched on all the lisp sites, but I couldn't find anything like that.

if they do not have coordinates z, and if you do not have to bring them to altitude, at this point it would be more useful a lisp than make simple offsets every 20 cm.

we say that the concept is the offset, but that it is not every 20 cm, otherwise the curves would all be parallel.
I look for a sort of offset, but given the space between the two curves, I adapt proportionally the distance of the new curves that I go to insert between the two dates.
In my concrete example, I have to add 4 level curves (polyline) among those I already have but being precisely level curves, they are never parallel, but they have to adapt to the morphology of the soil, and therefore be in every equally distant point.
doing this by hand is unthinkable and I hoped there was a suitable lisp

if you need then some "real" level curves it is necessary to find a lisp that first brings them to altitude, then you create the dtm of the ground and finally I would regrow the curves. otherwise, without this process, you can not add other levels of curves.
but if you want to do this on a wide cartography, it means that at least the fundamental curves are brought to the quota manually.
dots with coordinate z do you not have?

I can do it without a big problem.
So I should take them to the right z, then make a mesh, and get them the curves I need, right?
I found something like that... but I was hoping I'd give us a generic command for the 2d polylinee.
