Gravity In Revit

Few days ago, I saw a question about 'Hanging Fixtures on Slopes'.

The mission was, the hanging part has to maintain vertical while the cover plate follows a sloped ceiling.
Like this?
Well, it's very natural in real world because of gravity, but  there is no gravity in Revit.
But there are some features which help to imitate it. The Keyword is 'Vertical'.

Need Gravity!!!!!!!

1. Making Parts

To achieve this mission, two different parts are necessary in one family. Vertical part and Slope following part. At the next step, these will be nested in adaptive family. So, I made these in face based template. (Face based families can be easily placed on adaptive points,)  You can also make models in adaptive templates directly if you prefer.(I don't)

Cover Plate (for slope)

Lamp with stick (for vertical)

2. Making Adaptive Components

Place each of families above on each adaptive points in two different adaptive families.
And here are key options.

  • Options in the vertical part (Part#1)

There're two important options. One is Orientation of the Adaptive point and the other is vertical option in Family Parameters.

  • Options in the slope following part (Part#2)

3. Mixing

Make Part#1 nested in Part#2. At this step, there must be a point for joint in Part#2, and place Part#1 at it. The following image is the concept of this work.

Now, you have a family which can be hung on any sloped ceilings properly.

See how it works.

With this concept, you can make any hanging or standing fixtures on sloped faces you want. You can download the family here as usual.
(Please don't judge the ugly modeling.)

Enjoy. ;-)


  1. 좋은 글 잘 봤습니다. ^^

    1. 어인일로 여기까지 행차를..^^ 안바쁘신가봐요..

  2. Oh dont worry - worked it out

  3. I am working in Revit 2017 and am having a hard time finding the Adaptive Component Properties section while creating the "vertical" and "slope following" component families. Has this option been eliminated since 2014? Thanks...

  4. I found your posted family, and am figuring things out now. Thanks for sharing this!

  5. Where can we download these families to study?

  6. You make this sound misleadingly simple, when this is in fact a family within a family the the fourth degree.
