Read an Excerpt
Chapter 34: Three-Dimensional renderingAutoCAD has rendering capabilities. The render `package' with R12 is not a complete render system, in that shadows cannot be added. It is possible to add lights and finishes to models which will greatly enhance the model appearance and impress both employers and customers. Rendered images can be extracted from AutoCAD in BMP format for colour laser printing.
Only certain types of models can be rendered with AutoCAD, these being:
- extruded models
- 3D faced models
- 3D ruled-surfaced models
- 3D revolved-surface models
- 3D objects
- solid models - not considered here.
It is not my intention to cover render as a topic in this chapter. My aim is to show the user the potential of the render facility within AutoCAD and this will be achieved by a series of exercises covering the different render `types'. All of the examples are previous exercises from various chapters in the book and you should be familiar with them when you `see' them on the screen.
Render Example 1 - An Extruded Model
1. Open drawing EX34-1 from the 3DPACK directory.
2. The screen displays a single viewport of an extruded model from section 2 - Fig. 34.1. 3. From the menu bar select Render
4. The screen flips to Text with the following:
