Define slope

Hello all,

Is it possible with dynamo to do the task below? :

I have some floors in which I want to give a specific slope (2%) towards gutters in order to place afterwards the gutters in the correct height. The problem is that the altitude in each edge points change. The distance between the edge and the gutter also change.
I try to adapt the altitude of the sub-elements but it takes a lot of time and there are also many triangulated surfaces that are created.

Is there any way to do it faster ?
Thank you!

It is possible. Try with Floor.Addpoint, and Movepoint.
but I don’t think it’s possible to avoid appearing some triagulated surfaces.
