Modeling the AutoCAD Flatwork Base

This chapter details two specific methods for healing and generating faces to define surfaces using imported AutoCAD linework. Once imported into SketchUp, the AutoCAD flatwork lines are converted into edges but not faces. The imported edges will be used to create faces.

The process of modeling the Flatwork Base originating from AutoCAD differs from SketchUp Process Modeling outlined in Part 2. Typically, faces are produced when edges are drafted and connected to form a closed perimeter; SketchUp clearly understands where a face is desired.

Imported edges of predrafted closed perimeters and boundaries pose a challenge in SketchUp. Because they were not drafted in SketchUp, it is not clear where a face belongs and, in some cases, which edges are connected to which. SketchUp needs to be directed, so that it will understand where to create the faces.

As indicated, after the AutoCAD information was write blocked from the CAD_SU_Base, the flatwork information will enter SketchUp as a component. Before you work with either method, the base needs to be exploded (Fig. 18-1).

In some cases, the Flatwork Base will need to be exploded twice because it imports as a component within a component. Regardless, make sure that the linework is not a component when you start to heal the faces.
