Before you start adding content to a project, consider the following approaches to the design process:
Using levels. Begin the design process by defining levels for the model. See Levels.
Importing data. If you started the design process using another CAD program (such as AutoCAD), you can import existing data. Vasari imports various CAD formats, including DWG, DXF, DGN, and ACIS SAT files, as well as SketchUp (SKP) files.
