AutoBRIDGE 2027 for Revit 2027 27.6.4.7 (Smart 3D BIM Design)

Overview of AutoBRIDGE 2027

AutoBRIDGE is a high-performance Revit add-on developed by Bridge Works Software, built to revolutionize how bridge and infrastructure engineers model complex projects. The software addresses a fundamental challenge in infrastructure BIM: the disconnect between civil engineering design data (typically created in Civil 3D) and the BIM production environment (Revit).

Instead of manually re-entering geometry, engineers can use AutoBRIDGE to read alignments and profiles directly from an active Civil 3D file. When the alignment geometry changes, the Revit model updates accordingly, maintaining coordination and preventing costly rework. The add-in generates fully parametric Revit Families, meaning every component remains editable, schedulable, and coordination-ready for production-grade BIM deliverables.

The software supports a wide range of infrastructure elements, including bridge decks, girders, piers, pylons, retaining walls, tunnels, barriers, and set-out points.

Key Features of AutoBRIDGE 2027

AutoBRIDGE 2027 offers a comprehensive suite of tools for infrastructure modeling. Below are the primary feature modules.

Corridor Creation

Corridor Creation is the core feature of AutoBRIDGE. It enables users to generate parametric bridge corridors in seconds from Civil 3D alignments or imported 3D polylines. The tool supports two workflows:

• Civil 3D Method: Reads alignment and profile data directly from an active Civil 3D project.

• 3D PolyLine Method: Uses any 3D polyline from a linked DWG or imported CAD file, making it ideal for projects that do not use Civil 3D.

Both methods produce a Generic Model adaptive family instance tagged with AutoBRIDGE_Type = "AutoBRIDGE_Corridor", fully compatible with downstream tools like Pier Designer and Girder Automation.

Girder Automation

The Girder Automation module automatically places bridge girders, crossheads, bearings, and piers along an AutoBRIDGE Corridor. It calculates the exact 3D positions of every structural element across the full bridge length and places them in a single Revit run, with live Plan and Section previews before execution.

Abutment Designer

The Abutment Designer is a substructure module that places parametric Revit abutment families (.rfa) at precise start and end stations along Corridors, Civil 3D Alignments, or 3D PolyLines. It includes a rich library of parametric families for rapid deployment.

Multi-Corridor Parameter Control

Revit’s native Properties panel can only batch-edit instance parameters when all selected elements are of the exact same family type. AutoBRIDGE corridors often span multiple families, making native batch editing impossible. The Parameter Control tool solves this limitation by collecting every writable parameter across all selected corridor instances and presenting them in a single editable grid. Changes are applied to every selected instance in one Revit transaction, regardless of family type.

Array and Instance Tools

AutoBRIDGE includes several adaptive array tools:

• Array 4-Point Adaptive Family on Two Curves: Places repeated 4-adaptive-point families spanning between two curves in a single Revit transaction.

• Array 2-Point Adaptive Family: Selects a source 3D Mass or Adaptive Component and arrays elements along a curve.

• Corridor from 3D Mass: Generates a parametric bridge corridor by picking a curve edge directly from any 3D Mass or Adaptive Family already placed in Revit, with no Civil 3D or DWG import needed.

Superelevation and Variation Management

The Superelevation Management feature allows engineers to manage horizontal, vertical, and elevation variations along the corridor directly from Civil 3D or compatible data sources. Engineers gain precise control over design elements such as the top of retaining walls or the soffit of bridge decks using fixed levels, Civil 3D alignment profiles, and 3D polylines.

Family Manager

The Family Manager feature allows users to add templates for AutoBRIDGE, enabling automatic saving of templates within the add-in. This promotes the reuse of nested families across various projects and prevents duplication of work.

Set-Out Point Generation

AutoBRIDGE automatically generates consistent set-out coordinates from a single selected section point, repeated accurately along the alignment or corridor with fully user-defined station intervals. This is invaluable for construction and survey coordination.

How to Use AutoBRIDGE 2027

AutoBRIDGE 2027 is designed for infrastructure engineers and BIM specialists. The following workflow outlines the typical process for creating a parametric bridge corridor.

Creating a Corridor from Civil 3D

1. Open your Civil 3D project with the alignment and profile data you wish to use.

2. Launch Revit 2027 and open or create your bridge model project.

3. Navigate to the AutoBRIDGE ribbon tab and click “Corridor.”

4. Select the Civil 3D alignment from the active document. AutoBRIDGE will read the alignment and profile data.

5. Define the corridor parameters, including width, cross-section, and elevation variations.

6. Select Revit nested families for the corridor solid and void parameters.

7. Execute corridor creation. AutoBRIDGE generates a fully parametric corridor family instance in Revit.

Creating a Corridor from a 3D PolyLine

For projects that do not use Civil 3D:

1. Link or import a DWG file containing a true 3D PolyLine into your Revit project. The polyline vertices must carry Z elevation values representing the finished bridge profile.

2. Navigate to AutoBRIDGE → Corridor → 3D PolyLine from the ribbon.

3. Select the CAD layer containing the 3D PolyLine.

4. Identify the correct polyline by its total length.

5. Configure span definitions by drawing transverse cross-lines over the polyline. AutoBRIDGE auto-generates all span start and end stations from the intersections.

6. Execute corridor creation.

Placing Girders and Piers

Once a corridor exists, use the Girder Automation module:

1. Select the AutoBRIDGE Corridor in your Revit model.

2. Launch Girder Automation from the ribbon.

3. Configure girder spacing, crosshead positions, and bearing types.

4. Preview the placement in Plan and Section views.

5. Execute. AutoBRIDGE places all girders, crossheads, bearings, and piers in a single Revit run.

Managing Parameters Across Corridors

When working with long bridges that span multiple corridor families:

1. Open the Parameter Control tool.

2. Select multiple corridor instances from the Available Instances list. The tool lists all elements with a SubcategorySolid or SubcategoryVoid parameter.

3. Review the parameter grid. Parameters with different values across instances show [varies].

4. Activate the parameter rows you wish to change.

5. Enter new values and click RUN. All changes commit in a single Revit transaction.
