The Land[x] stair plug-in provides tools for creating and editing simple parametric staircases in Autodesk® Civil 3D®. The staircase is an Autodesk® AutoCAD® 3D solid and the parameters (height of riser, length of tread, width, landing and slope) are stored in a property set attached.

This tools are useful to landscape architects and engineers when using corridors for designing landscape paths. As the staircase is a solid it can be projected to profile views and as the parameter is in a property set it can be labeled with this parameter.

The plug-in is published as open source code, with the intention of encouraging other users to improve the code. More information regarding this plug-in and its code can also be found on the developers' website and github.
