What's new

The proven Pipe Route Concept has been expanded with a powerful calculation module. This feature enables duct and pipe dimensions to be determined easily, quickly, and precisely using the distribution network topology of the designed pipe routes in early design phases – based on existing space information.

Energy and volume flow data are taken directly from the MEP spaces. This allows designers to record central building data in LINEAR Building at an early stage and automatically transfer it to the MEP spaces:

• Heating demand → estimated heat loads
• Cooling demand → cooling loads using simplified methods
• Outdoor air volume flows → air quantity determination
• Waste water/potable water consumers → captured via the new Room Data Sheet module

Through feed-in, collection and transfer points – similar to the familiar "network start/end" objects – additional information relevant for dimensioning is assigned to the pipe routes:

• Definition of generation systems
• Assignment of system classes
• Differential Temperature (flow/return)
• Coverage of defined demands by respective systems
• Additional boundary conditions for calculation

By combining multiple rooms into supply zones with collection points, main routes can be dimensioned particularly efficiently. The calculated loads are automatically aggregated via the designed pipe routes and appropriately assigned systems in the start and end components and dimensioned section by section. The determined dimensions can then be used directly in the established pipe route concept – from defining cross-sections to automatically generating pre-sized pipes in the model.

Benefits at a glance

• Greater design reliability through early, precise dimensioning
• Significantly reduced design effort through automatic calculation
• Continuous data consistency from demand definition to model generation
• Efficient, transparent and BIM-compliant design across all disciplines

With this new calculation module, pipe route planning becomes an integral part of the early and preliminary design phases.

With the space data visualization, you can clearly display all parameters of your MEP spaces in a 3D view. The function creates colored visualization bodies for your selected space parameters in a temporary view – ideal for quick analysis and evaluation of your design data. This rprovides a clear visualization in all design phases that you can use for a wide variety of purposes: check room sizes, occupancy or room types early on, or quickly and intuitively verify the design temperatures. Continuous parameters such as temperatures or volume flows are visualized using customizable color gradients, while discrete parameters like room types or usage categories are automatically color-coded. Once the visualization meets your requirements, you can save the temporary view and convert it into a permanent Revit view that you can use anytime for plans or presentations.

Benefits at a glance

• Fast analysis through temporary 3D views with color-coded space parameters and automatic legends
• Flexible visualization of continuous and discrete data with individual color schemes
• Applicable in all design phases – from early space planning to final design verification
• Saving of reusable views for professional documentation and presentations

This innovative visualization tool makes complex space data instantly understandable and gives you full control over your analysis views at every project stage.

The Scheme Editor revolutionizes scheme editing: work directly on your schemes – whether derived from Revit models or transferred from LINEAR Building – without losing component connections. Moving elements automatically updates pipes and embedded components. No more manual adjustments, no broken connections. With intelligent layout functions such as repositioning, flipping, alignment, you can adapt your schemes to new requirements in seconds, not hours. All changes are reliably written back to the drawing view. Your scheme remains consistent and efficient.

Benefits at a glance

• Automatic connection updates – no manual adjustements needed
• Intelligent layout tools for fast and flexible adjustments
• Full model integrity from schematic to drawing view
• Seamless integration with Revit – bidirectional linking

With version 26.0, a frequently requested customer request from the LINEAR Idea Channel becomes reality: fixings can now be placed in linked MEP models. You organize your projects in separated discipline-specific models and want to display fixings in a separate model? From now on, you decide whether the ducts and pipes to be mounted are in a linked file or integrated in the same model. This flexibility seamlessly adapts to your individual planning workflow and enables more precise installation planning.

Benefits at a glance

• Fixings ar now also available in linked models
• Free choice of model structure according to your project requirements
• Optimized collaboration in discipline-separated planning processes
• Precise assembly planning across model boundaries

This highly requested function expands your design freedom and supports better modern, collaborative BIM workflows. Have ideas for new features yourself? Share them via the LINEAR Idea Channel and let other users vote!

With version 26.0, automatic scheme generation is extended to include the discipline cooling. You can create detailed cooling schemes directly from your 3D model with appropriate symbols and complete links to all components. Your 3D model remains the central source of information, while you can make targeted manual adjustments whenever needed.

Benefits at a glance

• Automatic scheme generation for cooling systems directly from the 3D model
• Consistent symbols and complete links to model elements
• Unified workflow for heating, potable water and cooling systems
• Flexible manual editing options available whenever needed

A frequent request from the Idea Channel: use manufacturer data without replacing the existing component in the model. As of version 26.0, this is now possible. The new function allows you to transfer relevant manufacturer data from the CAD Browser directly to components already placed in your model – without exchanging geometry.

This allows you to work with real manufacturer values for more precise calculations and realistic designs, while your model remains neutral and flexible. This is particularly valuable when you initially plan with generic components and later enrich them with specific product data – without fundamentally changing the model. Your design freedom remains fully preserved, while data quality is significantly enhanced.

Benefits at a glance

• Transfer manufacturer data from the CAD Browser to existing components – without component exchange
• Model remains neutral and flexible, but with real manufacturer data
• More precise calculations through high-quality product data
• No model changes necessary – maximum design freedom
