change level curve elevatedon at zero altitude

[wretcheddog]

Hello everyone! This is my first post:

I received a planimetry with level curves (see attached), the difference in height (the height) between a curve is the other is 20, unfortunately all the curves here drawn have a height equal to zero, having to create the topography on revit would create a flat surface and therefore should I change the height of each line on autocad by clicking the face line properties and after elevatedon, but is it tedious

This lisp could come in handy
