Mind Those Reference Planes!

It has been a few months since my last post about some quirkiness on adaptive components. I have this project using adaptive component to populate the building facade which posed some challenge not only with divide path direction; I stumped upon another unusual behavior with adaptive component and thought to write about this as part 2 on my blog.

For this building facade, we are using adaptive component to set up the window wall system module for number of reasons. One particular reason is that this facade has a sloping wall plane. As you might know, traditional curtain wall system doesn't work on non-vertical wall surface at all. One can try to use curtain system but it just doesn't work. Therefore, adaptive component with conceptual massing seems to be the answer for this question.

From the above image, each unit is composed by an adaptive component, there are a few different types of configuration in the facade. As we have modeled the whole facade, I notice something strange happening. Whenever I am trying to use dimension or align tool, these random "axis" started to show up. There are just so many of these axis no matter how many times you hit "tab" key to try to cycle through to something orthogonal to snap to.

I had no clue at first and thought Revit was going crazy on me. Then, I started examining the adaptive panel family and the answer was there.

Adaptive component (AC), just like any traditional family has two default reference planes, called Center (Front/Back) and Center (Left/Right). And by default, they are considered as "Strong reference" once the family is loaded to a project. However, reference planes in AC family do not serve any real purpose since "adaptive points" are taking their place on driving the geometry behavior. Unfortunately, those little reference planes are still pretty "snappy" in the project; and obviously, those reference planes become selectable more often than you expect and they appear at different angles depend on how they interact with the adaptive points as well as the massing.

Well, all you need to do is open the family (in my case, I have a handful of different type of families), select the Center (Front/Back) reference plane, and set it to "Not a Reference". Select the other one "Center (Left/Right)" ref plane and do the same, then you are good to go. Load it back to project and they are not snappy anymore!
