  • Duct Sizing: Size ducts automatically using constant velocity, constant pressure drop, and static regain calculations.
  • Building Load Calculations: Calculate building heating and cooling loads from within AutoCAD.
  • Pressure Drop Calculations: Calculate and document the pressure drop in your ductwork.
  • Ductwork Drafting: Draft your ductwork in both 2D and 3D.
  • 3D-BIM: Use BIM to check for collisions between the ductwork and your architect's Revit, Navisworks, or other 3D model.
  • Panel Schedules: Insert panel schedules directly in AutoCAD without having to use Excel.
  • One-line Riser Diagrams: Create one-line riser diagrams that update as the rest of your design changes.
  • Voltage Drop: Calculate voltage drop on feeders and branch circuits.
  • Fault Current Calculations: Calculate fault current at your panels.
  • Arc-Flash Calculations: Calculate arc-flash incident energy and flash-protection boundary distances.
  • Feeder and Wire Sizing: Size feeders, wires, and conduits automatically.
  • Lighting and Power Design: Design, draft, and circuit lighting and power layouts.
  • Photometrics: Calculate indoor and outdoor photometrics.
  • Quantity Takeoffs: Generate quantity takeoffs for estimation.
  • 3D-BIM: Use BIM to check for collisions between the conduit, cable tray, switch gear, and other electrical systems and your architect's Revit, Navisworks, or other 3D model.
  • Pipe Drafting: Design, draft, and document both plumbing and piping system layouts.
  • Isometrics: Generate isometrics from your 2D plans.
  • Pipe Sizing: Size pipes automatically based upon your building code requirements.
  • 3D-BIM: Use BIM to check for collisions between the pipes and your architect's Revit, Navisworks, or other 3D model.
