August 31, 2026
We are pleased to announce the release of Stabicad 26.09. This new version includes several key updates, improvements, and fixes to enhance your workflow and productivity.
We encourage you to install the latest version to take full advantage of these enhancements.

Below, you will find a detailed list of all the changes in this release.
Highlights of the 26.09 release
- Radiator heat output now uses the correct N-factor, including custom articles.
- Generating prefab sheets in Stabicad for Revit is substantially faster. On a customer model used in testing, generation dropped from about 3 hours to about 40 minutes.
Stabicad for Revit and Stabicad for AutoCAD | Heating and Cooling
- Correct N-factor in radiator heat output
Radiator heat output now uses the N-factor from the product line. Previously the exponent in the heat-output formula was not applied correctly: in AutoCAD the N-factor from the PLS file did not appear in Edit article and changing it did not recalculate power; in Revit the value was shown but rounded to two decimals and the calculated power did not match it. The N-factor is now read, shown to four decimal places, and used in the power calculation. If you overwrite heating power by hand, that override is kept and the N-factor is no longer applied.
Stabicad for Revit
- Generating prefab sheets in Stabicad for Revit is now significantly faster.
Benchmark testing on complex customer models showed generation times dropping from around 3 hours to just 40 minutes, a speed increase of over 75%. Opening the Manage prefab sheets window is also noticeably quicker because frame and title-block information is no longer reloaded from disk every single time you access it. All commands, workflows, and sheet layouts remain completely unchanged, enabling a big performance boost with zero learning curve.
- Updated Trimble Connect Publisher.
Stabicad for Revit includes an updated Trimble Connect Publisher for Revit 2023 through 2026, accessible via the Trimble Connect ribbon or through the dockable pane in the StabiTOOLS palette. Publishing models to Trimble Connect now triggers toast notifications within Revit to display real-time progress and status messages. When publishing, optional IFC files (preview) can be added using format checkboxes, while unselected checkboxes maintain the default Revit file format. The TrimBIM IFC classification now automatically follows Revit's export configurations and IFC type parameters, evaluating element, type, publisher override, category, and IfcBuildingElementProxy sequentially, ensuring MEP components retain proper IFC metadata rather than reverting to generic proxy objects. Additionally, Revit Rooms are included in published models by default, with options to toggle their visibility inside the Connect 3D viewer.
Stabicad for Revit | Electrical Installation Engineering
- Annotation offsets are now retained when adding add-on symbols.
Annotation offsets remain intact when adding add-on symbols to electrical families placed from the Stabicad palette in Revit. In previous versions (Revit 2024 onwards), attaching an add-on symbol caused the annotation to reset to the family origin across both hosted and non-hosted families. New projects in version 26.09 apply this fix automatically. For existing projects started on Revit 2024 or later, update to version 26.09, re-download all Electrical families, and execute Stabicad Electrical → Convert families to Current Version.
Ensure sufficient available disk space before initiating the conversion process, as Revit requires temporary storage during execution and may crash if drive space is low. Processing large models will require extra time (for context, an 83 MB project required approximately 27 minutes during testing).
Stabicad for AutoCAD | Ventilation
- Noise calculation now reflects selected room noise limits
Ventilation noise calculations now accurately evaluate room attenuation and required noise reduction using your specified noise limit. Previously, changing the noise limit in the rooms dB setting in StabiBASE (such as selecting NR 65 instead of the default NR 35) did not update the calculation, causing the report's noise limit row to fall back to NR 35 regardless of your selection. With this update, your chosen curve is applied directly to the evaluation. You can verify your selected limit post-calculation by navigating to Noise calculation per room → Results per device.
Stabicad for AutoCAD | Sanitary
- Tap water calculations with circulation now complete successfully
Tap water calculations that include circulation now complete smoothly when the default pressure loss factor is selected. Previously, this combination would fail with an unhandled error, typically at tees where two flows join, and prevent the report from generating. Calculations now complete as expected, and if any design issues exist, clear overview markup will pinpoint them rather than causing an unhandled error.
StabiBASE
- Central Revit models now open reliably from StabiBASE
StabiBASE now successfully launches central Revit models when using the Open and create local file prompt. Previously, attempting to open certain files via double-click in StabiBASE triggered an incorrect schema error, forcing Revit to crash. Central files now open smoothly directly from StabiBASE, matching the seamless behavior of opening files via Revit's native menu.

Trimble MEP makes Building Information Models (BIM) a reality by delivering solutions that transform disconnected workflows between stakeholders into a coordinated, constructible and actionable building model. To ensure a building is constructed in the most efficient way, the Trimble Constructible Process goes beyond BIM by creating models that use actual manufacturer content, allow for prefabrication and full clash detection, connect stakeholders to coordinate in real-time and bring the model directly from the computer to the field. This process optimizes the entire design, build and operate lifecycle.
