3.2 - Parametric Splicing for Typical Rebar

The "Parametric Splicing for Typical Rebar" feature in Revit 2025 introduces advanced capabilities for modeling rebar splices within a 3D structural model. This feature allows users to define the location of splices within rebar sets, control the lap length, and choose between uniform or staggered layouts, ensuring adherence to engineering and fabrication standards.

Parametric splicing essentially means that the splice locations and lengths can be determined based on parameters or rules, which can be predefined or adjusted as needed. This provides flexibility in the detailing process and ensures that changes to the model or design specifications can be rapidly implemented across the project.

Users can splice rebar sets by selecting the appropriate set or a reference line directly in the model, whether they're working in 2D or 3D views. They can define maximum and minimum lengths for the rebars, as well as specify the run-out positions, which is the part of the rebar extending beyond the end of the splice. Additionally, the feature allows users to simultaneously change properties of multiple splices between rebar sets, facilitating efficient updates and ensuring consistency across the model.

This functionality is particularly important for the accurate detailing and visualization of reinforcement in concrete structures, aiding in the planning of construction phases and the preparation of rebar for fabrication.

The "Prevent Unexpected Changes to the Rebar Model" feature in Revit 2025 is designed to maintain the integrity of a rebar design within a concrete structure model. It allows users to disable rebar constraints for individual bars or entire rebar sets, effectively locking their geometry to prevent automatic adjustments when changes occur in the concrete host geometry. This ensures that the specified positioning and detailing of the rebar elements are maintained throughout the design and revision processes.

For instance, if the dimensions of a concrete beam or column are altered, any rebars with constraints disabled would not automatically adjust to these changes. This is beneficial when certain rebar placements are finalized and should not be modified, even if the surrounding concrete geometry is.

The feature likely includes an interface where constraints can be toggled on and off with ease. It also appears to allow for manual dragging of rebar handles with constraints disabled, offering precise control over adjustments when necessary. Additionally, the use of schedules and filters to monitor the status of rebar constraints would aid users in managing the complex configurations of rebar within a model, ensuring that all elements are accounted for and properly set according to project specifications.

3.5 - Schematic Bar Bending Details for Rebar Tagging

The "Schematic Bending Details for Rebar Tagging" feature introduced in Revit 2025 is a detailed visual aid for conveying rebar bending instructions within the modeling environment. It enhances the representation of rebar layouts by embedding tags that show bending details directly in the model. This allows for a more informative and interpretable depiction of how each rebar element should be fabricated and placed.

The feature enables users to add schematic bending details that reference specific rebar elements, providing clarity on the bending shape required. With the ability to edit the visibility and appearance of multiple leaders for schematic bending details, users can customize how the information is displayed to better fit the project’s documentation standards. Users can also specify the width and height of the schematic bending details in the type properties, allowing for adjustments in the level of detail and scaling to fit different project scales.

Schematic bending details resemble bending schedules in the way that they scale the geometry of rebar shapes, adjusting the depiction based on the angle of bends, and are particularly useful for clearly showing rebar with standard 90-degree bends as well as those with non-standard angles. This feature streamlines communication between the design team and the construction personnel, ensuring that the rebar is fabricated precisely to the project's specifications.

3.6 - "Split" Features Enabled for Framing and Columns with Steel Connections

The "Split Features for Framing and Columns with Steel Connections" in Revit 2025 introduces new functionalities to handle the segmentation of steel structures. It includes two tools: 'split' and 'split with gap', which can be applied to steel framing and columns that have connections. This enhancement aims to give engineers and designers precise control over steel elements and their connections.

The 'split' tool allows users to divide steel members into separate parts, while the 'split with gap' tool goes further by introducing a specified gap between the divided sections. The gap can vary between 1.6mm to 304.8mm, accommodating different design and construction needs, such as for thermal expansion, construction tolerances, or to simply illustrate a detail in the design phase.

However, the 'split with gap' tool is not applicable to beams that are part of a beam system, truss, or a group, which may be due to the complexity or the interdependencies of these systems that could complicate the introduction of a gap. This feature is crucial for the detailed modeling phase of structural design, ensuring that the steelwork is accurately represented and can be understood and constructed correctly by the construction teams.

3.7 - Transfer Advance Steel Part and Assembly Marks to Revit

The "Use Advance Steel Part and Assembly Marks in Revit" feature in the 2025 update is geared towards enhancing interoperability between Revit and Advance Steel. It enables users to create general arrangement drawings for steel projects in Revit that are more closely integrated with the detailing processes in Advance Steel. This is accomplished by importing part and assembly marks from Advance Steel into Revit.

This integration ensures that the identification marks for parts and assemblies used in Advance Steel, which are crucial for the fabrication and assembly of steel structures, are consistent and accurate in the Revit model. This consistency is critical across design, fabrication, and construction stages, as it allows for clear communication and efficient coordination between different teams working on the project.

With this feature, users can transfer the detailed numbering and marking systems of steel components from Advance Steel into Revit. These marks are essential for tracking individual parts and their respective positions in the overall steel assembly. This could include the placement of bolts, plates, and other connections within a steel structure, facilitating the generation of accurate and informative construction documents directly from the Revit model.

5.1 - Array of 1 or 0 in Families

Revit 2025 introduces the capability for designers to create families with arrays that can have a count of 0 or 1, expanding the flexibility and control within the Family Editor. Previously, array counts could not go below 2, which could be limiting in design scenarios. With this new update, manufacturers and design firms that work extensively with Revit families can significantly reduce the time and effort required for family maintenance and offer improved compatibility. For example, furniture arrays can be adjusted to show no chairs by setting the array count to 0, while still keeping the table visible in the model. This refinement means some older family content may need to be updated to harness these new array capabilities. However, it's important to note that this feature is exclusive to the Family Editor and does not apply to project-level array creation.

5.2 - Batch Delete and Add to Material Library

5.3 - Improved IFC Export Category Mapping Table

The IFC Export Category Mapping Templates feature in Revit 2025 allows for customization of category mapping for IFC file exports. This means that users can now more precisely control how Revit categories are defined within the IFC data structure.
