Analytical Model in Revit – Essential Skill
The Analytical Model in Revit is used for structural and energy analysis, helping engineers understand how a building will perform under loads and forces. It is a simplified representation of the physical model used for analysis and simulations.

1. What is an Analytical Model in Revit?
The Analytical Model is a simplified version of structural elements (beams, columns, walls, slabs) that helps with:
✅ Structural Analysis – Load distribution, stress calculations.
✅ Energy Analysis – Heat loss, solar gain, HVAC loads.
✅ Coordination with Structural & MEP Engineers – Export to analysis software.

📌 Tip: The Analytical Model exists inside the Structural Discipline in Revit.

2. Enabling the Analytical Model
A) Check if Analytical Model is Enabled
Select a Structural Element (Wall, Floor, Beam, Column).
In Properties, look for "Enable Analytical Model" and make sure it is ON.
Go to Manage Tab → Structural Settings → Analytical Model Settings to adjust tolerances.
📌 Tip: You can turn the analytical model ON/OFF per element or control it for the entire project.

3. Viewing the Analytical Model
Go to View Tab → Visibility Graphics (VG).
Under Model Categories, enable "Analytical Model Categories".
Switch to "Analytical Model" View in 3D or Elevations to see only the analytical lines.
📌 Tip: Analytical elements appear as simplified lines, representing forces and connections.

4. Adjusting & Editing the Analytical Model
✅ Manually Adjust Elements:

Select an analytical element → Use Move, Align, or Trim tools.
Adjust Nodes & Connections to fix errors.
✅ Set Load Conditions:
Select an analytical element → Go to Properties → Analytical Properties.
Define Load Cases, Supports, and Boundary Conditions.
📌 Tip: Use "Analytical Adjustments" to modify model behavior before exporting to analysis software.

5. Exporting the Analytical Model to Structural Software
A) Export to Robot Structural Analysis
Go to Analyze Tab → Structural Analysis.
Click "Robot Structural Analysis" to export the model.
Perform analysis in Robot and send results back to Revit.
B) Export to Other Software (SAP2000, ETABS, StaadPro)
File → Export → Structural Analysis Format (SAF) or IFC.
Import into ETABS, StaadPro, or SAP2000 for further calculations.
📌 Tip: Always review the analytical model for connectivity issues before exporting.

6. Analytical Model for Energy Analysis
✅ Used for HVAC load calculations, daylight studies, and thermal performance.
✅ Enabled via Energy Settings:

Go to Analyze Tab → Energy Optimization.
Define Building Envelope, Insulation, and Heat Gains.
✅ Send model to Insight 360 or Green Building Studio for energy simulations.
📌 Tip: Ensure analytical surfaces are properly assigned for accurate results.

🚀 Quick Summary:
🔹 Analytical Model = Simplified representation of structural and energy performance.
🔹 Enable in Structural Settings & Visibility Graphics (VG).
🔹 Modify nodes, supports, and load
