In this blog, ATG Technical Specialist Quentin Worm demonstrates how to create slanted ceilings in Revit.

Pick a Room

To make the slanted ceiling, you want it to consist of at least 3 ceilings- lower, upper, and slanted. First, you will need a room that you want to put a slanted ceiling in. For example, I made a regular room to make it easy.

Once you have a room ready to create the lower part of the ceiling, you can use any shape you want, as long as you leave room to add the upper ceiling and slanted ceiling. The example below is 8′.

Now that you have the lower ceiling created, you will need to create the upper ceiling. Make sure that you leave a gap between the lower ceiling and the upper ceiling.

Offset from Base

Now that you have the upper ceiling made, we will start on making the slanted ceiling. The style I chose will require creating four different slanted ceilings. First, I will add a line to one of the lower ceiling’s side. Then, I will add a line directly across from it. Lastly, connect the ends to create a closed sketch. Select the link attached to the lower ceiling and in the properties, click to turn on the “Defines Constant Height.” Once you click that, change the “Level” from none to Level 1. Now, set the “Offset from Base” to the height of the lower ceiling and you are done with that line.

Once you finish the line attached to the lower ceiling, select the line attached to the upper ceiling. You will repeat the same step, and set the “Offset from Base” to the height of the upper ceiling.

I will repeat this process three more times to create the style I want.

If your ceiling does not look uniform in the section, this means the top part of the slanted ceiling is way off and you forgot to change the “Level” from none to Level 1.

If you try to do all four slants in one ceiling, instead of splitting them up, you will get an error. When I get this error, I know I am doing too much and need to create separate ceilings.

There you have it folks, how to create slanted ceilings. Just remember that each ceiling needs to be a separate ceiling for the more complex ceiling styles. You can see that mine took 6 separate ceiling to create. Thank you for reading.
