Create Coach Sweep
You can access this dialog from the following:
Ribbon: OpenRail Modeling > Miscellaneous
The Sweep Envelope tool calculates approximate corridor swept by rolling stock represented by single coach.
It is not a kinematic envelope calculation tool. It attempts to calculate true swept corridor including rail head wear or rail side wear or all other parameters defined in respective norms. It calculates only area swept by freely rolling stock. That means calculation in sequential manner location of bogies lying on rails determining 3D position of entire rolling stock item. Sections generated at different stations along centerline being sum of rolling stock item sections in different rolling stock locations and eventually stitching per station generated sections into volumetric mesh representing swept corridor.
Coach Definition
Setting |
Description |
Template |
Rolling stock is defined by custom rolling stock section. |
Bogie Base |
Location of bogies. Required to define 3D model of rolling stock. |
Rear Extension |
Rear extension of the rolling stock from bogie location. |
Front Extension |
Front extension of the rolling stock from bogie location. |

2D Swept Path Creation
The Coach Sweep tool does not create a 2D swept path.
To create a 2D swept path, you can create a terrain model using the Coach Sweep mesh as a boundary and then display the boundary as 3D linear elements to be copied into a 2D drawing.
