The objective of the Autodesk(R) Revit(R) 2021: Site Planning and Design guide is to enable users who have worked with the Autodesk Revit software to understand concepts and tools related to site planning and design. This guide covers the Revit coordinate system, which is used to coordinate multiple files in a single project, as well as the elements and tools that are used to create topographic surfaces for site work and add structural elements. Topics Covered Site Planning: Understanding the Revit coordinate system, positioning, true north, and project north.Linking files.Relocating the project elevation.Working with shared coordinates by acquiring and publishing coordinates.Exporting Revit models to .DWG.Site Design: Creating topographic surfaces.Adding property lines and building pads.Modifying toposurfaces with subregions, splitting surfaces, and grading the regions.Annotating site plans and adding site components.PrerequisitesAccess to the 2021.0 version of the software, to ensure compatibility with this guide. Future software updates that are released by Autodesk may include changes that are not reflected in this guide. The practices and files included with this guide might not be compatible with prior versions (e.g., 2020).Knowledge of the basic techniques of the fundamentals of the Autodesk Revit software covered in the Autodesk(R) Revit(R) 2021: Fundamentals for Architecture guide.
