There are four commands available to input source data into a drawing for the development of a site model; each uses a different type of source information.
● Import Survey File
● 2D Polys to 3D Contours
● 3D Polys to 3D Loci (Vectorworks Landmark only)
● Grid Method Entry
In addition, stake objects, 3D loci, or 3D polygons can be used directly as the source data for the site model. No conversion is necessary before using this type of source data.
The Modify by Record command can convert 2D polygons or polylines with attached record elevation data directly to 3D contours at the proper elevation. See Modifying Objects by Record Value.
Before you create the site model, check the source data with the Validate 3D Data command to ensure that a valid site model will be created.
