H2X Engineering
Cloud-based mechanical and plumbing design platform that calculates pipe sizing, heat load, duct sizing, and drainage in real time as you draw, with AutoCAD and Revit integration.
Hidden Pricing
4.0 /5 composite score
The best-reviewed MEP design platform for small firms -- 4.8/5 from 55 Capterra reviews with 5.0/5 customer service, real-time pipe/duct sizing as you draw, and Revit/AutoCAD integration; opaque pricing (contact sales only) caps value at 2 and makes solo budgeting impossible without a sales conversation.
