In-Depth Information
As shown in Figure 7.10, a complex surface is generated in Rhino by drawing two curves and
using the Extrude Curve Along Curve tool. Note that some reference geometry was exported
from a Revit model to DWG and linked into this study in Rhino.
A flat surface model is enough to generate a roof by face; however, it may be difficult to see
the imported surface, so use the Extrude Surface tool to give it a thickness. Once the surface is
complete (Figure 7.11), select only the double-curved geometry, choose File
➢
Export Selected
Objects, and choose the .sat filename extension. SAT will generate the cleanest geometry for
curved solids and surfaces.

You can download the Rhino file (c07-Roof-Face.3dm) and SAT export (c07-Roof-Face.sat)
from this topic's web page. You can also download the sample Revit project and continue the
