Autopath 2017

Swept Path Analysis &
Vehicle Turn-in Simulation Software

Autopath is an easy to use add-on for vehicle swept path analysis on BricsCAD and AutoCAD for civil engineers, transportation professionals, architects and urban planners. Autopath is most commonly used to analyze vehicle maneuvers on roads, intersections, roundabouts, parking lots, construction sites, airports, loading bays and more. Autopath is not limited to the provided libraries of vehicles, as you can use the software to define specialized vehicles, like cranes, telescopic trailers and more.

Autopath is available in PRO & LT version:   View Comparison Table

“We do a lot of geo-technical and site design work, especially for the natural gas industry here in West Virginia. We use Autopath to ensure there’s plenty of clearance for the specially designed drills rigs as they’re moved along access roads to their hilltop drill sites.”

swept path analysis

Autopath features several interactive methods of swept paths analysis based on vehicle speed, road superelevation, lateral friction, and turn radius algorithms while supporting analysis simulations for multiple vehicles on the same path.

Autopath adaptive horizontal and vertical vehicle swept path analysis can be linked to the road centerline, road edge, road curb or any other user defined line, polyline, or alignment. Desired offsets can be set for the front, or for the back vehicle axle. The swept path analysis will dynamically update whenever the vehicle path is changed.

EasyDrive analysis method features interactive forward and reverse vehicle turn prediction with optional “full lock on stop” capability for difficult maneuvers. You also have the flexibility to work with previously created analyses, either through editing the existing analysis, or by continuing on and adding to it.

Horizontal and vertical swept path simulations enable users to check vehicle side and vertical (overhead and underside) clearances. Vehicle steering parameters, radius value and slope values for vertical simulations are presented at all stages of the simulation and provide all the data needed for vehicle & analysis inspection.

Various display options for any single swept path simulation give unlimited possibilities to generate visually appealing simulations:

  • Wheel trails,
  • Vehicle axis center point,
  • Vehicle outer edge,
  • Layer options,
  • Line type and hatch options,
  • Color display.

In order to achieve maximum visual representation, especially at the critical sections, the speed of the simulation can also be controlled.

Autopath provides a range of swept path analysis reports:

  • Horizontal and vertical vehicle contour and parameters display,
  • Dynamic steering wheel parameters diagram.
  • Vehicle collision detection for side objects, overhead and underside objects.
  • A Swept path width labeling option for the inspection of maximum width values at any point along the curve.
turning analysis

Autopath includes a list of predefined country specific vehicle design libraries:

With the custom vehicle design option, users can extend existing vehicle libraries, or create completely new county specific libraries of vehicles that are otherwise not included in the software. Vehicle definition import/export tools are also included allowing new vehicles to be conveniently shared with the team.

 Custom vehicles

Autopath enables definition of a comprehensive set of vehicle parameters including: vehicle geometry, number of axles, vehicle track width, number of wheels per axle, wheel spacing, tire radius, tire width, steering options for each axle and others. Combined with various steering definition options like steering calculation, turning cycle parameter and turn time value definitions it gives user the ability to generate geometrically correct and realistic swept path analysis.

Specialized vehicles

Further options for horizontal and vertical vehicle contour design give users extended capabilities to define vehicles with high levels of details. Vehicle contour option supports adding load shapes to a vehicle for even greater swept path analysis capability. And horizontal and vertical simulations will include collision detection for any added loads.

This extensive customization options enable users to define highly complex specialized vehicles like: forklifts, cranes, telescopic trailers, log trailers, farm vehicles, multi trailer vehicles, articulated buses and other vehicles with multi axles and multiple steering wheel definitions.

Autopath PRO features functionality for importing raster and elevation data into a DWG drawing at a click of a mouse. Select location, adjust zoom to the desired area to be imported, check whether you want to import Raster, Elevation data or both and select the appropriate country specific coordinate system*. Data is seamlessly inserted into your drawing.

(*) Users have the option to request additional country specific coordinate systems if they are not yet included in the list.

In order to deliver a reliable solution that meets demanding industry requirements, our engineers closely cooperate with academic scientists, renowned vehicle manufacturers and specialists from various companies that perform swept path analysis on challenging projects.

Autopath uses internationally recognized mathematical algorithms and models. CGS Labs engineers perform also field tests and measurements on actual vehicles to double check software results. Software is subjected to extensive methodical testing before each release.
