Revit Skillfully Uses Subcategories to Manage Model Visibility
Revit has eliminated the concept of layers, which can be uncomfortable for many users. Those unfamiliar with layers might not miss them, and some rely on color coding instead. However, distinguishing hundreds of elements by color can be challenging. If you prefer using RGB values for differentiation, that’s a valid approach as well.
Personally, I consider the concept of “layers” one of humanity’s greatest inventions. Recently, I have been researching volumes and the various lines involved, which require frequent visibility control. Since Revit no longer supports layers, we rely on subcategories. These subcategories prove quite useful, functioning similarly to layers, but with one limitation: they only work within a single category and cannot be shared across multiple categories.
For example, if I want to use different types of lines to divide a volume surface, using reference planes would create a cluttered image. Instead, I use model lines and create several subcategories under the model lines category. This approach allows me to differentiate line types and easily control their visibility.
