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.
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'.
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)
2. Making Adaptive Components
Place each of families above on each adaptive points in two different adaptive families.
And here are key options.
There're two important options. One is Orientation of the Adaptive point and the other is vertical option in Family Parameters.
- Options in the vertical part (Part#1)
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.
(Please don't judge the ugly modeling.)
