It 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. It's available in the Autodesk Appstore for download
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.
