AutoBRIDGE Corridor Workflow

Step 1: Prepare Civil3D Document

01Open Civil3D File

Before beginning, open the Civil3D file containing the target alignment and profile. Important: Ensure your Civil3D version matches the AutoBRIDGE settings (Settings → Civil3D tab). If you change this setting, restart Revit to apply the changes.

Step 2: Launch Corridor Workflow

02Open AutoBRIDGE → Corridor

In Revit, navigate to the AutoBRIDGE ribbon tab and select the Corridor tool to launch the generation interface.

Step 3: Select Alignment & Profile

03Data Selection

Select your active Civil3D document from the dropdown menu. Then, choose the specific Alignment and its associated Profile that will define the vertical and horizontal path of your corridor.

Step 4: Family & Subcategory Configuration

04Assign Nested Family

Switch to the Family tab. Select a template and your desired nested family (or add a new one via the Family Manager). Map your geometry by assigning solid elements to the Solid subcategory and internal voids to the Void subcategory.

Step 5: Define Chainages & Frequency

05Input Stations

On the Chainages tab, define your start and end stations. Each row represents a separately controlled corridor span, allowing for different settings per segment. Use the Frequency column to control the spacing between adaptive sections.

Step 6: Generation Settings

TIPOptional Advanced Settings

You can fine-tune the Section Arrangement (Start, End, From Center, or To Center) and other parameters within the Settings → Corridor tab to control how families are placed along the spans.

Step 7: Run & Finalize

06Process Corridor

Click the Run button. AutoBRIDGE synchronizes with Civil3D to extract live geometric data, automatically generating 3D parametric adaptive corridor families directly within the Revit environment.

07Success Confirmation

Upon completion, a success message will appear. Your corridor is now a fully parametric Revit model, accurately driven by Civil3D geometric data.

Pro Tip: If your corridor geometry appears "faceted" or low-detail, return to Step 5 and decrease the Frequency value. Always ensure your Civil3D profile is saved and up to date before running the process.
