Overview

Following on from the success of 'Beginning AutoCAD', this package takes the novice CAD user through the basics to more specialised CAD techniques. This is very much a software-based package. The notes fully explain the features under discussion in Bob McFarlane's popular and accessible style, but the real advantage of this book lies in the two disks included in each package. These contain all the worked examples and activities outlined in the notes and thus create a self-contained tutor. The inexperienced user can create impressive drawings after only a few hours tuition.

This package is ideal for students of construction and engineering, but home users of AutoCAD will find this package simpler and more accessible than traditional CAD manuals and will allow the user to achieve impressive results faster.

Chapter 34: Three-Dimensional rendering

AutoCAD 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
Render
4. The screen flips to Text with the following:
