Description
The Landscape Terrain Modeller (LTM®) plug-in for Autodesk® Revit® makes it easy for landscape architects to work in Revit.
The LTM® plug-in includes 11 powerful tools that enable you to quickly and easily modify Floors in Revit by defining a slope. Just type in the slope pointing out the starting point and the elevation at the end point is automatically calculated, and the floor will be modified.
Furthermore, the LTM® also includes 4 functions to create Filled Regions attached to floors to visually improve your plan drawings for presentations. Filled regions created with the LTM plug-in are connected to the floor with the same shape as the floor and can be automatically updated if the shape of the floor is changed.
