Analytical Model in Revit – Essential Skill<br />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.<br /><br />1. What is an Analytical Model in Revit?<br />The Analytical Model is a simplified version of structural elements (beams, columns, walls, slabs) that helps with:<br />✅ Structural Analysis – Load distribution, stress calculations.<br />✅ Energy Analysis – Heat loss, solar gain, HVAC loads.<br />✅ Coordination with Structural & MEP Engineers – Export to analysis software.<br /><br />📌 Tip: The Analytical Model exists inside the Structural Discipline in Revit.<br /><br />2. Enabling the Analytical Model<br />A) Check if Analytical Model is Enabled<br />Select a Structural Element (Wall, Floor, Beam, Column).<br />In Properties, look for "Enable Analytical Model" and make sure it is ON.<br />Go to Manage Tab → Structural Settings → Analytical Model Settings to adjust tolerances.<br />📌 Tip: You can turn the analytical model ON/OFF per element or control it for the entire project.<br /><br />3. Viewing the Analytical Model<br />Go to View Tab → Visibility Graphics (VG).<br />Under Model Categories, enable "Analytical Model Categories".<br />Switch to "Analytical Model" View in 3D or Elevations to see only the analytical lines.<br />📌 Tip: Analytical elements appear as simplified lines, representing forces and connections.<br /><br />4. Adjusting & Editing the Analytical Model<br />✅ Manually Adjust Elements:<br /><br />Select an analytical element → Use Move, Align, or Trim tools.<br />Adjust Nodes & Connections to fix errors.<br />✅ Set Load Conditions:<br />Select an analytical element → Go to Properties → Analytical Properties.<br />Define Load Cases, Supports, and Boundary Conditions.<br />📌 Tip: Use "Analytical Adjustments" to modify model behavior before exporting to analysis software.<br /><br />5. Exporting the Analytical Model to Structural Software<br />A) Export to Robot Structural Analysis<br />Go to Analyze Tab → Structural Analysis.<br />Click "Robot Structural Analysis" to export the model.<br />Perform analysis in Robot and send results back to Revit.<br />B) Export to Other Software (SAP2000, ETABS, StaadPro)<br />File → Export → Structural Analysis Format (SAF) or IFC.<br />Import into ETABS, StaadPro, or SAP2000 for further calculations.<br />📌 Tip: Always review the analytical model for connectivity issues before exporting.<br /><br />6. Analytical Model for Energy Analysis<br />✅ Used for HVAC load calculations, daylight studies, and thermal performance.<br />✅ Enabled via Energy Settings:<br /><br />Go to Analyze Tab → Energy Optimization.<br />Define Building Envelope, Insulation, and Heat Gains.<br />✅ Send model to Insight 360 or Green Building Studio for energy simulations.<br />📌 Tip: Ensure analytical surfaces are properly assigned for accurate results.<br /><br />🚀 Quick Summary:<br />🔹 Analytical Model = Simplified representation of structural and energy performance.<br />🔹 Enable in Structural Settings & Visibility Graphics (VG).<br />🔹 Modify nodes, supports, and load
