Special Note All of the work presented within this tutorial is based on TurboCAD Pro V17.2. Although users of previous versions are welcome to try the tutorial it cannot be stated what results will be achieved. Many changes, some subtle and others not so subtle, are made with each program revision. Although many steps and directions would be generic some may not be. The same can be said for tools between versions. Older versions may not have the same tools as Pro V17.2 and if the same tools are available the tools themselves may have been revised and hence, work in a different manner than they previously did. 2

4 Introduction The grain auger, which seems so simple at first glance, offers many opportunities to hone one's CAD skills. It is with this in mind that this tutorial has been written. Within the tutorial the reader will be led through each keystroke to produce most of the components of the auger that is illustrated on the cover of the tutorial. Much of the carriage is supplied to save tutorial time but the challenging part of aligning and positioning it is addressed within the tutorial. The reader will also learn how to set up their drawing, how to insert standard lighting and how utilize render scene luminance. The reader will learn how to establish a render scene environment and the reader will learn how to render their drawing and save it in a high resolution image format. This tutorial is in no way intended to teach mechanical design or construction but rather it is intended to teach the use of some of the tools that TurboCAD has to offer and to introduce the new user to a drawing methodology. The author feels confident that the techniques outlined within the tutorial can help lay the foundation for future successful TurboCAD drawing and illustration for even the newest user. As with any technically advanced software, the user is generally faced with a steep learning curve. It is the hope of the author that the money and time spent working through a Textual Creations tutorial will help ease the learning and allow the reader to come away feeling confident that they made a wise decision. This tutorial will assume that the reader has the Platinum edition of TurboCAD Pro V17.2 with its extra architectural and mechanical tools, although no Platinum specific tools are used that the author is aware of. There are many ways to approach a project and it is likely that each person using the program would proceed in very different ways, so be open to alternative methods as experience builds. What is important is that the user becomes familiar with the objects that they wish to model and begin to look at them in a different way than they might otherwise do. What primitive shapes make up the whole? What will be required of these primitive shapes early in the drawing and how will this affect needs further along? What component or components should be started with? Many questions can only be answered through experience, but hopefully some of them will be answered by the time the beginner has worked through this tutorial. There is a great deal covered in this tutorial and the author urges the beginner to be patient, to read very carefully and to take the time necessary to do a good job. Try to enjoy the process as much as you will enjoy the final results. This tutorial assumes that the beginner has studied the desktop to some degree and can locate most of the tools. Since there are endless desktop configurations that can be set up in TurboCAD the author has opted to illustrate the required tools with the Office 2000 user interface, and the default toolbars in their undocked format (Office 2000 theme). The author is also running a Windows 7 basic theme, hence the look of the various program windows. TurboCAD cannot run an Aero Theme in Open GL Acceleration so it gets turned off when TurboCAD gets started. 4
