Complex Slabs and Paths

Modelling complex floors, roofs, footpaths etc....

Revit is not there yet when it comes to modelling complex slabs with falls in different directions, or footpaths on a steep and varied site, this tutorial tries to fill the gap.
We are going to model a footpath on a steep site with a few given RL�s (Relative Levels), and put a curb on it that will follow the path.

1. open a new project and click on the �site� tab
2. click the �toposurface� and proceed to create your shape using points.

3. Finish surface and go to 3D view, my path looks like this:

4. While in 3D view, export to DWG, for clarity reason, we�ll call it �path�
5. Start a new massing family, File->New->Family...
6. Go to 3D view and import the DWG we created 2 steps ago.
7. Save the Mass family and call it �path Mass� and load it into your project.
8. In your project, click the �Massing� tab and choose �Place Mass� go to 3D view for a better view.

9. Click �Roof By Face� edit the roof and change properties to suit you, I changed it to a 200mm concrete roof with a paving render. Pick the whole mass and click �create roof"

10. Revit will create your roof, in order for you to see it, you will need to hide mass. Now our path looks like this:

As you can see, Revit uses triangulation to interpolate the point and that leaves some lines on the path, you can use the �Linework� tool to get rid of these lines and clean up your path.

11. Next, we are going to add a curb to our path, Under the �Modelling� tab click Host Sweep->Roof Fascia, choose your profile and click on the edges of the path to create your curb, to look like this:

This tutorial can apply to many situations and it�s only a base for you to explore further. This is how my path looks like now:
