The product is intended for HVAC engineers, building services specialists, and BIM designers. It combines equipment and network modeling, aerodynamic calculations, design verification, and construction documentation preparation.
The current version is Model Studio CS 3.0, build 7680. Service Pack 2 was released in October 2026.
3D HVAC System Design
Model Studio CS Отопление и вентиляция allows engineers to place equipment and create piping and ductwork directly in a building's 3D model.
Design work uses library components with geometric and technical properties. Conceptual modeling and system creation from standard minicatalog components are supported.
- Create heating pipelines.
- Model ventilation ducts.
- Place equipment and fittings.
- Create parallel pipelines.
- Create bypasses and U-shaped sections.
- Set and edit pipe slopes.
The software can automatically connect selected points with piping or ductwork, generating the required bends.
When a route changes, connected components are adjusted, and lengths and dimensions are recalculated based on the updated geometry.
Aerodynamic Calculations
Model Studio CS Отопление и вентиляция supports aerodynamic calculations for ventilation systems.
Input data consists of airflow rates at terminal components, including grilles, diffusers, and other devices. The software calculates airflow rates and aerodynamic characteristics of the network.
Results are stored in model properties and can be used to generate calculation tables, drawings, and diagrams.
The 2026 update introduced tools for showing and hiding the ventilation calculation model and improved rectangular tee selection and rectangular duct construction.
Engineering Design Verification
The software includes tools for checking object self-intersections and specified permissible clearances. Users can configure custom verification rules and save them for future use.
When violations are detected, a report is generated, and the affected components are highlighted directly in the model.
With CADLib Модель и Архив, users can check clashes between HVAC systems and structures, pipelines, and utilities from other project disciplines.
Documentation Generation
Documents for the HVAC discipline are automatically generated from the information model:
- Equipment and building services layout plans.
- Piping and ductwork views and sections.
- Axonometric and isometric diagrams.
- Heating system plan diagrams.
- Equipment and material specifications.
- Calculation tables and schedules.
The software automatically adds elevation markers, dimensions, leaders, and item numbers. Documents can be exported to Microsoft Word, Excel, RTF, and directly to nanoCAD drawings.
Compatibility
The current version runs on the nanoCAD Platform 24.1–26.0 with the 3D module. Windows 10/11 and officially listed Linux distributions are supported.
When used with CADLib Модель и Архив, the HVAC information model can be included in the overall building project.
CAD.kz can help select a license, implement the software, and arrange training for HVAC engineers.

FAQ
Can ventilation calculations be performed directly in the model?
Yes. The software performs aerodynamic calculations of ventilation networks based on specified airflow rates. Results are stored in the model and can be included in documentation.
Can axonometric diagrams be generated automatically?
Yes. Model Studio CS generates axonometric and isometric diagrams with dimensions, elevation markers, and item numbers.
How can ventilation clashes with other building systems be checked?
The software supports checks within the model. CADLib Модель и Архив is used for coordination with related disciplines and allows clash detection in the combined model.
