Custom Revit Add-Ins & Automation Tools
Custom tools built by Ashhar to turn hours of tedious, repetitive design work into one-click automated actions, saving hundreds of engineering hours.
Standard 3D modeling involves thousands of manual, repetitive clicks. I write custom software programs (in C# and Python) that do the heavy lifting automatically—eliminating human errors and speeding up project delivery by over 60%.
Plant Room Pre-Construction Clash Resolution
Interactive Comparison: Initial Services Routing vs Coordinated LOD 350 Model
Level of Development (LOD 100 to 500)
How a building model evolves from a rough idea into a fully coordinated, site-ready digital twin that anyone can understand.
Concept
The Rough Idea- Rough 3D shapes: Shows general building size, volume, and layout on the site.
- Early space planning: Estimates general space needed for main plant rooms and utility risers.
Schematic
The General Layout- Approximate pathways: Shows approximate paths for main duct runs, large pipes, and walls.
- System placeholders: Establishes where major systems will travel through the building.
Detailed Design
Exact Engineering Dimensions- Real physical sizes: Modeled to true dimensions, specific shapes, and gravity slopes.
- Multi-discipline ready: Ready for structural and architectural spatial coordination.
Coordination Ready
Clash-Free & Site-Ready- Real connections modeled: Includes actual pipe hangers, valves, flanges, and wall sleeves.
- Zero site conflicts: Coordinated across all trades so nothing collides during construction.
Fabrication
Ready to Manufacture- Factory-ready details: Exact cut lengths, sheet metal seams, and bolt connections.
- Off-site assembly: Workshops can directly manufacture components straight from the 3D model.
As-Built
Real-World Digital Twin- Field-verified replica: Updated to 100% match what was actually constructed on the job site.
- Lifelong building operations: Handed over to owners for facility management and maintenance.
