Revit Architecture: Creating Sloped Floors

In this Revit Architecture tutorial I am going to show you how to edit your floor elements in order to add sloped surfaces to them. If you would like to watch the video version of this tutorial first, simply click in the box below….

 

 

Please note that you need to have created a regular Revit Floor element “first” before you start manipulating it’s surfaces. In the image below you can see that I’ve created simple rectangular floor element. This is more than sufficient to demonstrate the tools in question.

 

 

 

Let’s switch to a floor plan view of element…..

 

 

Go ahead and select the floor element by clicking on it. Once it is selected take a look at the ribbon menu. Note how you now have access to a panel of “Shape Editing” tools….

 

 

 

 

These tools allow you to edit and manipulate the planar surfaces that make up your floor element. Let’s start off by adding a “Point” on to the upper surface of our floor. Go ahead and select “Add Point”….

 

 

 

 

What we are going to do is add a point to the upper surface of our floor. But instead of the point being coincident with the surface plane (i.e. being flush with it in terms of height), we are going to create it “lower” than the surface plane. Revit will then tessellate the surface- thus forming a shallow, inverted pyramid.

 

 

First set the height of the Point. You do so by entering it’s “Elevation” (or “Height”) into the box on the Options Bar…..

 

 

 

 

Leave “Relative” checked on. This means that the value that you enter for the “Elevation” is “Relative” to the upper surface of the your floor element. I’m going to enter “-100”. That is, I want my point to be 100mm LOWER than the upper surface of my floor element….

 

 

 

 

With the Point’s Elevation set, go ahead and click in the active view to place the point. Make sure you place it “within” the boundary of the floor element!

 

 

 

 

As soon as you place the point, Revit resolves the new surface by triangulating it…..

 

 

 

If we switch to a 3D View it is far easier to see what is going on….

 

 

 

You can envisage that this point may represent a drainage point in our floor that we want to slope down to. At any point in time you can remove all “Shape Edits” to your floor by use of the “Reset Shape” function. Just select the floor and choose “Reset Shape” from the end of the Ribbon….

 

 

 

 

Quite often you do not want to slope the “whole” of the floor element- but just a small part of it. You do this by cordoning off the area you wish to triangulate using “Split Lines”. Select your floor element and then select “Split Line” from the ribbon menu….

 

 

 

 

Now simply add lines to section off the area of the floor that you are going to then add a Point to….

 

 

 

You can see in the image below that I have sectioned off a rectangular area of the floor….

 

 

 

All I need to do now is add a point- just as we did before. But now Revit will only triangulate the area inside the Split Line Boundary….

 

 

 

If we switch to a 3D View we can clearly see the triangulated, sloped section of our floor. This could be (say) a walk-in shower in the corner of a wet room.

 

 

Key Points:-

  • You can use Shape Editing tools to manipulate the surfaces of your floor elements
  • Create you floors in the normal manner first
  • Once created, select the floor element and then use the Shape Editing tools accordingly
  • Remove all “shape edits” to your surfaces by means of the “Reset Shape” tool
