Special Note All of the work presented within this tutorial is based on TurboCAD Pro V18.1. 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 V18.1 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 antique cannon is a pretty remarkable device when one considers the carpentry and blacksmith skills that are required to construct and continually maintain its structure when dealing with the forces imposed upon it. This seemingly simple model is actually quite complex and its construction requires some definite forethought as will be seen while working through the tutorial. The amount of hardware required to hold the cannon together and to anchor it to the ship, where it would likely be found, is enough to tax TurboCAD and requires special attention to the onboard ACIS settings. Within the tutorial the reader will be led through each keystroke to produce all components of the antique cannon that are illustrated on the cover of the tutorial. Aside from learning how to draw in TurboCAD, the user will learn how to set up the drawing and how to insert standard lighting. 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 the fundamentals of cannon 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 18.1 with its extra architectural and mechanical tools. Although no architectural specific tools are used there are some Platinum specific tools that are used. 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). 4

5 Please remember that any supplied images and files are for use within the tutorial only and may not be shared or sold to others. The supplied hdr image is available from Paul Debevec's Light Probe Gallery but has been supplied for convenience. Visit: For those working through the tutorial in pre-v18 versions please note that most of the functions described in the tutorial, as being on the Modify menu, were on the Format menu in previous version of the program. Also note that render times are much better in V18 than one will see if using previous versions of TurboCAD. TurboCAD now uses Multi-Threading for renders and can make use of multiple processors. The author has a fairly new Acer with 6 processers and has enable 5 for rendering. This is looked at as part of the set up further along. Lastly, the Copy in Place tool has finally been reintroduced into TurboCAD as a permanent tool. Users who don't have this new tool will need to use the Make Copy method. That is to select the object to copy in place, select the Make Copy tool to turn it on, tab into the first field on the Inspector Bar but don't change anything and simply press Enter. Select the Make Copy tool again to turn it off. BUG in TurboCAD Pro v18.1 build 51.2 (found under Help / About) There is an ACIS bug discussed fully on pages It outlines what is wrong and offers a fix that comes in the form of the dll file that has been supplied with the tutorial materials. Use the dll only if you have TurboCAD Pro v18.1 build 51.2 or the steps listed on those pages indicate that it is required. It is the understanding of the author that this has been fixed in later test builds and will likely be found in newer versions offered to the public, if they have been released. 5

6 2D Carriage Profiles The 2D profiles for the cannon carriage will now be created, working towards what is illustrated in the image below. Switch to Left view. Select Plane by Active View from the Workplane toolbar. To begin creating the lower portion of the side bracket, select the Rectangle tool from the Line toolbar. 24

7 Select the Polyline tool from the Line toolbar. Select Coral from the color dropdown menu on the Property toolbar. Using six V SEKE snaps and two I SEKE snaps, place the first eight points of the polyline, as indicated in the picture below. Right mouse click and select Close from the local menu.

Switch to Isometric SE view. Select Plane by World from the Workplane toolbar and disengage Auto Workplane by Face if it is still on. A bend line will be required on the bottom of the flags extrusion. Select the Line tool from the Line toolbar. If need be, orbit the drawing a bit (mouse wheel pressed while moving mouse) so that the lower central vertexes are clearly visible. Using two V SEKE snaps, place a line as indicated in the picture below. 226
