Understanding the difference is crucial for accurate design, documentation, and coordination.
1. What Are Model Elements? Model elements are 3D components that define the actual building structure and systems. They exist in all views and can be scheduled or quantified.
🔹 Types of Model Elements Category Examples Host Elements Walls, Floors, Roofs, Ceilings Component Elements Doors, Windows, Furniture, Pipes Structural Elements Beams, Columns, Foundations MEP Systems HVAC, Pipes, Electrical Fixtures 📌 Tip: Model elements appear in 3D views, sections, elevations, and schedules.
2. What Are Annotation Elements? Annotation elements are 2D and exist only in the view where they are placed. They provide documentation, dimensions, and notes for construction drawings.
🔹 Types of Annotation Elements Category Examples Text & Dimensions Text Notes, Linear & Angular Dimensions Tags & Symbols Room Tags, Door Tags, North Arrow, Section Marks Detailing Detail Lines, Filled Regions, Keynotes View-Specific Components Revision Clouds, Legends, View Titles 📌 Tip: Annotations do not appear in 3D views because they are view-specific.
3. Key Differences Between Model & Annotation Elements Feature Model Elements Annotation Elements 3D or 2D? 3D 2D Visible in multiple views? Yes No (view-specific) Affects construction? Yes No Modifiable in 3D View? Yes No Scheduled & Quantified? Yes No 📌 Example: A wall (model) is visible in 3D and section views, while a dimension (annotation) is only visible in the view where it was placed.
4. Controlling Visibility of Model vs. Annotation Use Visibility/Graphics (VG)
Turn off annotations when working in modeling views. Hide model elements when creating detailed 2D drawings. Use View Templates
Apply a Detailing Template to annotation-heavy views. Apply a Modeling Template to keep views clean. Use Detail Levels
Coarse – Simplifies model display. Medium – Shows more details. Fine – Full detail with all model components. 📌 Tip: Keep annotations separate from model elements to avoid clutter.
🚀 Quick Summary: 🔹 Model Elements = 3D, physical building parts (walls, pipes, furniture). 🔹 Annotation Elements = 2D, view-specific details (text, dimensions, tags). 🔹 Model elements appear in all views; annotations are limited to one view. 🔹 Use VG (Visibility Graphics) & View Templates to manage visibility.
