The smart, free alternative to AutoTURN and Autodesk Vehicle Tracking. Simulate vehicle maneuvers, check truck turning radii, and export CAD-ready drawings directly in your browser. No signup required to start.
See how PathSweeper simplifies your workflow.
Upload your site plan as PDF, JPG or PNG — or import directly from satellite imagery.
Select the design vehicle and draw the path intuitively with your mouse. Swept paths are calculated in real-time.
Export the result as high-resolution PNG or JPEG (DXF when you imported a CAD file), ready for project documentation.
Use PathSweeper for free for quick checks or pay only per project for audit-proof export data.
Perfect for quick feasibility studies and internal coordination.

From first swept path to final proof — here's our roadmap.
All standard vehicle classes, from cars to articulated buses. The four free standard vehicles are generic templates with typical dimensions (not the official RBSV 2020 design vehicles).
Passenger car, delivery van, 2-axle truck and city bus with typical dimensions (generic templates, not the official RBSV 2020 design vehicles).
Official RBSV 2020 design vehicles (passenger car, truck, bus, refuse truck). Semi-trailer and articulated bus arrive together with the articulated-vehicles update.
Vehicle types and dimensions as required by fire authority specifications for access road verification, plus refuse collection vehicles.
Multi-part vehicles with realistic articulation behavior.
Editor for individual design vehicles with your own dimensions.
Extending the library with AASHTO (USA), Austroads (Australia) and DMRB (UK).
Physically accurate swept paths in real time — no approximations. Benefit from our precision calculation engine.
Realistic wheel angle calculation for precise turning circles.
Instant visualization of the total space requirement.
Swept paths with rate-limited steering arcs: gradual, physically accurate steering transitions instead of instantaneous angle changes.
Simulate reversing maneuvers with realistic steering behavior.
Semi-trailers, articulated buses and trailer combinations with multiple axle groups.
Seamless integration into existing planning workflows — no media breaks. Compatible with your favorite CAD tools.
Load site plans and floor plans as background images.
Use aerial imagery directly as a scaled planning base.
Edit swept paths directly in CAD software.
Standards-compliant documentation with dimensions and legend.
In-depth references on swept-path geometry, fire-truck access and design vehicles by country.
Fire truck access in Germany and the US: what DIN 14090, IFC and NFPA actually regulate, why the official dimensions are licensed, how to source them legally and which values you may use freely for pre-design.
RBSV 2020 design vehicles explained: what they are, how to obtain the official dimensions, which tools include the RBSV 2020 design vehicles, and which free alternatives are sufficient for pre-design and feasibility studies.
What swept path analysis is, the geometry behind it, and a worked pen-and-paper example. A universal civil-engineering primer with diagrams, formulas, and a step-by-step calculation for a typical passenger car.
Latest articles on swept path analysis and access planning
Realistic swept path simulation in the browser: rate-limited steering replaces the instant arc with a clothoid wheel-swing, like desktop tools. Try it free, save with a one-time Projekt Pass.
Export any calibrated swept path analysis as DXF for AutoCAD, BricsCAD or Allplan. A placeable reference point becomes (0,0) so it snaps exactly into place.
Swept paths for semi-trailer trucks: how an articulated tractor + trailer corners, max 16.50 m per § 32 StVZO, typical curve radii, and what planners need to watch out for.
What is the BO-Kraftkreis? § 32d StVZO explained simply: outer 12.50 m, inner 5.30 m, public-domain, and the pragmatic way to plan swept paths without an RBSV 2020 license.
Aerial ladder DLK 23/12: comparison of publicly available manufacturer datasheets (Magirus M32L-AT vs. Rosenbauer L32A-XS vs. Iveco Magirus), why it is the German design vehicle, and where to source the licensed standard dimensions.
Turning bays in dead-end streets: hammerhead, T-shape and circular variants, why the exact dimensions reside in the licensed RASt 06, public-domain sources for pre-design and the most common planning mistakes.
How planners in the US, UK, Australia, Canada and Germany find legally usable garbage truck dimensions: which design-vehicle catalogues to license, which statutory maxima are free to cite, and which manufacturer datasheets give defensible pre-design values.
For free and with no signup, you can draw paths and compute swept curves directly in your browser with four standard vehicles (passenger car, delivery van, 2-axle truck, bus). You can calibrate scale on a site plan (including PDF site plans), draw turning paths, see the swept envelope in real time, and export as PNG/JPEG. The Projekt Pass (€29 one-time per project) adds the official RBSV 2020 design vehicles, custom vehicles, DWG/DXF upload and DXF export.
The free tier includes four generic standard-vehicle templates with typical dimensions, similar to the RBSV 2020 reference vehicles: a standard passenger car, a delivery van, a 2-axle truck, and a standard bus, not official RBSV 2020 reference vehicles, but sufficient for feasibility studies and plausibility checks. The Project Pass adds the official RBSV 2020 design vehicles (incl. refuse truck) and a custom-vehicle editor where you can enter dimensions from your own manufacturer data sheets. Articulated vehicles (semi-trailers, articulated buses) and fire apparatus (DLK 23/12) are in progress and will follow in a later update.
No: the four free standard vehicles (passenger car, delivery van, 2-axle truck, city bus) are generic templates with typical dimensions, not the official RBSV 2020 design vehicles. They are sufficient for feasibility studies and plausibility checks. The €29 Project Pass includes the official RBSV 2020 design vehicles (passenger car, additional truck classes, city and coach bus, refuse truck) and the custom-vehicle editor. Not yet included but in progress: articulated vehicles (semi-trailer, articulated bus) and fire apparatus. The aerial ladder dimensions from DIN EN 14043 / DIN 14502 (DIN Media GmbH) are not yet licensed. Note: the authoritative version of the FGSV regulation is the latest edition, available from FGSV Verlag, www.fgsv-verlag.de.
PDF site plans can be uploaded for free as a background: drop a PDF into the upload modal and calibrate the scale like any other site plan. DWG and DXF upload, plus DXF export, are included in the Projekt Pass (€29 one-time per project). As a separate free tool, you can use our public DWG to DXF converter without an account.
Yes. Swept-path calculation, calibration and PNG/JPEG export are permanently free and run entirely in your browser, with no signup required for the basic flow, no tracking cookies, and no third-party tracking. We use self-hosted, IP-anonymized analytics only. Only the optional Projekt Pass (€29 one-time per project) for RBSV 2020 vehicles, custom vehicles and CAD export is paid.
No. PathSweeper runs entirely in your web browser (Chrome, Edge, Firefox). It is a lightweight alternative to installing heavy CAD plugins or vehicle tracking software.
