3D models don't have to stay 3D; BricsCAD can flatten them with a variety of commands, each with their pros and cons. The Flatten command flattens the entire 3D model to a series of 2D lines and polylines that look "3D"; the FlatShot command does similarly, but makes a copy and then lets you specify the look of hidden lines (such as dashed, colored).
By contrast, the XEdges command makes copies of individual edges on 3D models as 3D splines and circles; while XFaces command extracts faces as 3D surfaces.
After completing this lesson, you will be able to:
- Understand how to flatten 3D models
- Extract edges and surfaces from 3D models
- Know how to use Flatten and FlatShot, and XEdges and XFaces
