Floor outline to walls in dynamo (newbie)

Hello! Very new with dynamo. What I want to do is create walls from the outline of all the floors in my project. I’m trying to do it myself but it’s getting a little hard for me to understand how to get the outlines of all floors. Thnks a lot in advance

Welcome to the community!

What have you tried so far? Sample files like the sample RVT to replicate the environment that you’re working in and the DYN which you’ve built to this point go a long way towards helping you attain your goals. Short of that we have to guess at which version of Revit you’re in, what version of Dynamo you’re using in that Revit build, how many floors you want to work on, and what direction you want the graph’s architecture to go. Then we have to build a sample for all of the above which is a lot of extra work…

Offhand you can try collecting the sketch lines from the floor and then use a Wall.ByCurveAndLevels node to generate the walls.
