ETAP alternatives
If ETAP is not the fit, the strongest mep design alternatives here are Stabicad, H2X Engineering, and CoolCalc. Stabicad brings Subscription, no verified agent access, RFA, DWG, IFC formats. H2X Engineering brings Contact sales, no verified agent access, DWG (AutoCAD), JSON (AutoCAD import format), Revit RVT (via add-in), PDF formats. CoolCalc brings Per project, API agent access, PDF (MJ8 reports), JSON (API responses) formats.
This page compares every reviewed same-sub-category peer for ETAP, using the same verdict, score, pricing, agent-access, and format signals as the main hub.

MEP Design alternatives comparison
| Tool | Verdict | Composite | Price signal | Agent access | Key formats |
|---|---|---|---|---|---|
| Stabicad C3 5/5 reflects the Revit and AutoCAD plugin workflow plus the 30,000+ manufacturer BIM family library, while C4 5/5 and C5 5/5 reflect RFA, DWG, and IFC portability with Revit, AutoCAD, and MEPcontent integration. C2 stays 1/5 because no public API, CLI, or MCP surface is documented. | Worth it | 4.0 | Subscription | None | RFA, DWG, IFC |
| H2X Engineering C4 5/5 reflects DWG, JSON, RVT, PDF, and Excel/CSV exchange; C5 4/5 reflects AutoCAD, Revit, and CIBSE-linked workflows; and C2 2/5 reflects no public API, CLI, or scripting surface. Pricing is contact-sales, and firm-size fit is solo to small-team. | Solid | 3.8 | Contact sales | None | DWG (AutoCAD), JSON (AutoCAD import format), Revit RVT (via add-in), PDF |
| CoolCalc C2 4/5 reflects the documented REST API with HTTP Basic Auth, and C3 4/5 reflects the self-serve per-project model. PDF MJ8 reports and JSON API responses define the export surface, and integrations include LennoxPros, AHRI matchup data, and email delivery. | Solid | 3.4 | Per project | API | PDF (MJ8 reports), JSON (API responses) |
| Carrier HAP C1 5/5 reflects a public one-time-license model, while RF2 and C2 1/5 reflect no public API, CLI, or scripting surface. gbXML import plus CSV, EnergyPlus EPW, NOAA TMY3, ASHRAE IWEC2, and PDF report workflows define the exchange surface; firm-size fit is solo to small-team. | Solid | 3.2 | One-time | None | gbXML (import), CSV (export), EnergyPlus EPW, NOAA TMY3 |
| DDScad RF1 remains attached because pricing is quote-required, C4 4/5 reflects IFC, DWG, DXF, and gbXML interoperability, and C5 4/5 reflects Graphisoft Archicad and BIMx integrations. C2 2/5 reflects no documented API or scripting surface. | Solid | 3.0 | Quote-only | None | IFC, DWG, DXF, gbXML |
| Wrightsoft Right-Suite Universal C1 4/5 reflects published subscription pricing, and C4 4/5 reflects PDF and report output plus the Right-CAD add-on and AHRI database connectivity. RF2 and C2 1/5 reflect no public API, CLI, or scripting surface; firm-size fit is solo to small-team. | Situational | 2.8 | Subscription | None | Right-Suite project files, PDF, reports |
| AutoCAD Plant 3D Specialized niche for plant and process engineering -- AutoCAD Plant 3D delivers robust piping and P&ID workflows with standards-based equipment catalogs (ANSI, ISO, manufacturer libraries) and 3D coordination, but the subscription-only model (bundled in AutoCAD; no standalone purchase) and learning curve limit adoption to specialized mechanical/process engineers and EPC firms that already invest in AutoCAD. | Situational | 2.8 | Quote-only | API | DWG, IFC |
| MagiCAD RF1 and RF2 keep C1 2/5 and C2 1/5 because pricing is quote-only and no public API, CLI, or MCP is documented. C4 4/5 reflects RVT, DWG, IFC, and DGN workflow coverage, and C5 4/5 reflects Revit, AutoCAD, BricsCAD, and MagiCAD Cloud integration. | Situational | 2.6 | Quote-only | None | RVT, DWG, IFC, DGN |
| AutoCAD MEP C2 2/5 reflects desktop automation through the OMF API, AutoLISP, and ObjectARX rather than a documented cloud API, and C4 4/5 reflects DWG plus partial IFC export. RF1 remains attached because pricing is bundled behind Autodesk subscription pages. | Situational | 2.6 | Quote-only | API | DWG, IFC, Excel |
| AutoCAD Electrical C2 2/5 reflects desktop scripting through AutoLISP, VB.NET, C#, C++/ARX, and VBA rather than a documented web API, C4 4/5 reflects DWG plus WDP/WDD and CSV/XLS/XML exchange, and C5 3/5 reflects the AutoCAD, SQL Server, Microsoft Access, and Revit-via-IFC connections. RF1 remains attached because pricing is bundled behind Autodesk subscription pages. | Situational | 2.6 | Quote-only | API | DWG, WDP/WDD, CSV/XLS/XML |
| Elite Software Rhvac C1 4/5 reflects the one-time-license model, while RF2 and C2 1/5 reflect a GUI-only workflow with no API, CLI, or scripting surface. gbXML, PDF, EnergyPro, REM/Rate, Ekotrope, REScheck, Energy Gauge USA, and AHRI database links define the exchange surface; firm-size fit is solo to small-team. | Situational | 2.4 | One-time | None | gbXML, EnergyPro project files, PDF, Rhvac project files |
| Trimble SysQue The MEP placement is Revit-native fabrication detailing with Trimble Connect, PypeServer, and FabShop integrations plus IFC and PSVR export. RF1 and RF2 keep C1 2/5 and C2 1/5 because pricing is contact-sales and the product has no standalone API, CLI, or scripting surface outside the Revit add-in; C5 4/5 reflects the integration stack. | Situational | 2.4 | Quote-only | API | RVT, IFC, PSVR |
| Augmenta The MEP placement is the Revit round-trip electrical raceway workflow; C5 4/5 reflects native Revit plus SysQue interoperability. RF1 and RF2 keep C1 1/5 and C2 1/5 because pricing is quote-based and no public API or scripting surface is documented. | Situational | 2.2 | Quote-only | None | RVT |
