CADPIPE HVAC Tutorial
i
 Welcome to the CADPIPE HVAC Tutorial. CADPIPE is an AutoCAD-based HVAC design and drafting program for preparing two-dimensional and three-dimensional HVAC designs. Using CADPIPE, you can create drawings and design HVAC systems faster and more accurately than with traditional meth-ods. You can customize specifications to reflect how you design and install ductwork. CADPIPE stores your design criteria and creates drawings using your shop specifications.  When you use CADPIPE, you create much more than a drawing. Your CADPIPE drawing is a data-base containing precise locations, sizes, and attributes of the ductwork you draw. After you complete the drawing, you can retrieve and analyze this information to generate Bills of Materials for estimating, ordering, shipping, and installation.  This tutorial is a guide to help you evaluate the CADPIPE HVAC software.It is important that you have a working knowledge of AutoCAD and have completed and understood the instructional materials available for the AutoCAD software before attempting this tutorial.  This tutorial is designed to follow an order that reflects how a draftsman would design or draw a duct system. The HVAC system we used could be designed in any number of more efficient ways but has been developed to expose you to as many drawing features of the CADPIPE program as possible.
Tutorial Organization
 The CADPIPE tutorial has been organized to include many of the timesaving features of the CADPIPE HVAC program. While it would be impossible to highlight every aspect of the program, we believe that after completing these exercises you will have a good working knowledge of CADPIPE.  All AutoCAD commands referenced in the tutorial (Zoom Window, e.g.) are shown in CAPITAL LETTERS while all CADPIPE commands (Walls, e.g.) are shown inbold text. This tutorial is written under the assumption that you are using a mouse and selecting commands from the toolbars or pull-down menus. All CADPIPE system prompts are in italics and the appropriate responses are numbered consecu-tively. Note: Be sure that you have gone through the instructional materials for your AutoCAD software. The CADPIPE tutorial assumes that you have a basic working knowledge of AutoCAD.
Installation
If you are evaluating CADPIPE HVAC (running the demo program without hardware locks), the program will run fully functional for 25 days from the date of installation. This should provide adequate time to discover the time saving benefits from easily drawing one 3D model, one time, and generating as many views and sections as necessary that will automatically be updated every time the model is changed. It virtually eliminates having to draw and redraw multiple orthographic views.
Place the CADPIPE CD into your CD ROM drive If “Autorun” is enabled on your system, the installation screen will appear. ( If not, you will need to open your Windows Explorer, select the CD ROM drive, and double click on the “startcd.exe” file. From the first screen, select the “Install Products” icon. On the next screen, select “HVAC.” This will begin the installation process. The following screens will then appear:
oWelcome screen oLicense Agreement oCADPIPE information oInstallation Type –I f you are installing the full licensed version and have been given an installation serial number, then you should select “Imperial” or “Metric”.
o Demo-If you are evaluating the software, then you should select “Imperial Demo” or Metric Demo”. You will not be prompted for an installation serial number. oUser information oDestination folder oSelect components to install oWhether you will be running CADPIPE on Architectural or Mechanical Desktop. Select “no” if you will be running it on straight AutoCAD 2000i, 2002, or 2004.
CADPIPE will then be installed on your system. Remember, if you are running the Demo version, it will expire after 25 days.
Before You Begin
i
 Make sure you have followed the installation instructions provided with this tutorial CADPIPE program. Included with your software is a drawing called Hvac.dwg. This is the drawing you will use as you work through the CADPIPE tutorial. Creating the Drawing
 Click the HVAC icon in the Windows Desktop. Open the drawing called Hvac.dwg. When a drawing appears on the screen, you will see that some of it is already completed. Use this drawing as you work through the tutorial.All system prompts in the HVAC tutorial are in italics and your responses are shown numbered. In addition, the metric equivalent to an imperial measurement appears in brack-ets: (600).

1-1 Chapter 1. Menus/Toggles  Provided with the CADPIPE HVAC software are pull-down menus and toolbars containing all the functions needed to complete HVAC designs and drawings. They are automatically loaded when you start a CADPIPE session and can be activated from within the drawing. CADPIPE replaces the AutoCAD standard pull-down menus with a combination of AutoCAD and CADPIPE pull-downs. The CADPIPE pull-downs available areRect,Rnd/Oval,CPTools,Arch,Accs, Spec, andDrawing Sheets.  The HVAC Menu has three main toolbars: stieitUlin/igesD,Rectangular, andRound and Oval. These toolbars contain many commonly used commands found in the pull-down menus. Figure 1-1 lists the CADPIPE commands associated with each HVAC toolbar button:
Rectangular Toolbar Configure Start a Run Join to Undo Back Auto-Route Collision Check On/Off Straight Cut-to-Length Design/Utilities
Turn Up Turn Down Routing Line CADPIPE Query HVAC Reports
Round and Oval Toolbar Configure Start a Run Join to Undo Back Auto-Route Collision Check On/Off Straight Cut-to-Length

2-1 Chapter 2. Architectural Features
 This chapter will introduce you to important features you can use to create background drawings for your HVAC designs. In many cases, you will be able to secure working drawings from an architect or engineering firm and will not have to draw them. To show a few basic architectural funtions available in CADPIPE HVAC we will place three walls, a ceiling grid, and beams. SelectArchfrom the pull-down menu to bring up theBeams, Joists, Lights, Grid, Walls,andColumnscnuf .snoit
CADPIPE automatically place sall architectural features on their own layers. You can control these colors and layers by using theConfigurecommand found on theArchpull-down menu. Walls
