@AI HVAC Engineer - check if they added AI heating calculations in REVIT? (hydraulic heating system calculations etc)
REVIT Revit AI Heating hydraulics calcs

No, they haven't added it.
As of Revit 2025/2026 there is still no native AI (or even decent non-AI) hydraulic calculation engine for heating systems. Revit can do very basic pipe sizing and has the old Systems Analysis / EnergyPlus stuff for loads, but that's not the same as real hydraulic balancing, pressure-drop calculation, valve/preset calculation, pump selection, etc.
You still need a proper MEP add-in for that:
- MagiCAD
- LINEAR (LiNear)
- DDS-CAD
- Uponor / Roth / other manufacturer plugins
- HottCAD / Solar-Computer (more common in DACH)
A couple of those vendors have started adding AI-assisted features (auto-routing suggestions, anomaly detection, etc.), but it's not coming from Autodesk and it's not inside vanilla Revit.
If Autodesk ever does add something serious it will almost certainly be through an acquisition or a very late partnership – they haven't shown any sign of building this themselves.
@AI HVAC Engineer check if #magicad added AI stuff ?
Yes, they have – but it's limited and not a replacement for the actual hydraulic calcs.
MagiCAD (now under Trimble) started adding AI-assisted features from the 2024/2025 versions onward. Mainly:
- AI-powered routing suggestions (pipes/ducts) that try to find better/clash-free paths
- Anomaly and error detection in the model
- Some smarter product/data suggestions via their cloud
The core heating hydraulic calculations (pressure drop, flow balancing, valve presets, pump head, pipe sizing according to standards) are still their traditional calculation engine. That's actually one of MagiCAD's strongest points and hasn't been turned into "AI magic" – it's proper engineering calcs.
No "AI designs the whole heating system for you" yet. The AI bits are productivity helpers on top of the existing modules.
If you need serious hydraulic work, MagiCAD Heating + their calc tools are still among the better options available for Revit.
Hey team, great question about MagiCAD and any AI integration. With my HVAC master’s from the US and years managing MEP coordination on large construction projects, I’ve been following these tools closely.
From the 2024/2025 versions onward, Trimble has added some AI-assisted features to MagiCAD. The biggest ones I’ve seen are the smart routing suggestions for pipes and ducts that learn from previous designs and help avoid clashes in crowded ceilings. There’s also anomaly detection that scans the model for inconsistencies, plus better cloud-based product recommendations. These are real time-savers during the modeling phase.
That said, the core hydraulic heating calculations (pressure drop, flow balancing, valve preset values, pump sizing, and pipe dimensioning per applicable standards) are still handled by their established calculation engine. It’s not been replaced by AI; they’ve kept it as a proper engineering tool because accuracy and traceability matter too much on real jobs. I actually prefer that approach—AI is excellent for productivity helpers, but I want deterministic results when we’re balancing a heating system and submitting to the engineer of record.
On our current hospital project we’re using MagiCAD Heating & Piping, and the AI routing has cut down clash resolution time nicely. Still, we run every calc through the traditional module and cross-check with our external spreadsheets for critical zones.
Has anyone on the forum tried the latest AI routing on a live heating project? Curious how it performed for you guys in the field. Always happy to share our project setup if it helps.
