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 V16.2 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.

Introduction Where would new CAD users be without all the interesting objects that can be found in the world of railroading? Most of these objects are excellent subjects to practice drawing with, and with so many free resources available online the whole process is made quite easy. Although the handcar design in this tutorial is based roughly on resources discovered on the internet, the author has made many changes to make it better suited to this tutorial. Within the tutorial the reader will be led through each keystroke to produce all components of the railroad handcar that is illustrated on the cover of the tutorial. The reader will learn how to create each object by manipulating 2D profiles and 3D primitive shapes. The reader will 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 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 full edition of TurboCAD Pro V16.2 with the current Architectural and Mechanical add-ons, although no architectural specific or mechanical 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 V16 user interface, and the default toolbars in their undocked format (Office 2000 theme).
