Corridor Creation from 3D Polyline

01Insert Polyline Alignment

Before beginning, insert your 3D polyline as an alignment in your Revit project. Then navigate to AutoBRIDGE → Corridor → 3D Polyline.

02Choose Layer & Polyline

In the Alignment tab, select the 3D polyline layer name. Then choose the specific polyline by selecting its layer length.

03Assign 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 solids to the Solid subcategory and internal voids to the Void subcategory.

04Input Start & End Stations

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

Use the Lines option by drawing a group of horizontal cross lines. Name the group appropriately, select it in the Lines option, and press OK. AutoBRIDGE will append a list of start and end stations for every span based on the group lines.

TIPFine-Tune Section Arrangement

You can adjust the Section Arrangement (Start, End, From Center, or To Center) and other parameters in Settings → Corridor to control the placement of families along each span.

06Generate Corridor

Click Run. Upon completion, a success message will appear. Your corridor is now a fully parametric Revit model, accurately driven by the 3D polyline.
