There are definitely some things that I love about Revit, that I consider a vast improvement on AutoCAD and 2D drafting. One of my favorites are the use of hard-coded categories instead of user defined layers. This makes standardization on a project much easier, but there’s also a ton of flexibility that can create issues for users. It helps to have a clear understanding of how the categories are to be used and see some changes Autodesk has made to expand the categories.
Every object in a project is divided in object style categories. Model, annotation, analytical model and imported objects represent the four primary object styles that can be edited and defined in a project.
Model objects are for physical representations of real-world objects. These include additional filters by these disciplines:
- Architectural
- Structural
- Electrical
- Mechanical
- Piping
- Infrastructure
Autodesk has been expanded the default categories…
