CADPIPE Building ServicesTutorial

Welcome to the CADPIPE Building Services Tutorial. Building Services is an AutoCAD basedHVAC and Pipe design suite. This tutorial assumes you that you have a working knowledge of AutoCADand understand its interface and commands. It has been developed to expose you to as many drawingfeatures of CADPIPE Building Services as possible.

In it you will learn how to:

• Use Building Services powerful drawing commands to create and edit Pipe runs and HVAC designs. Work with Auto-Route, Auto-Elbow, and Auto-pipe to draw Pipe, and Auto-Route for

HVAC.

• Insert Fittings into Pipe runs.

• Place Valves using the valves database.

• Place and Connect HVAC accessories (diffusers, fire dampers, etc.).

• Use simple Architectural functions by placing beams.

• Create an Automatic Section View.

• Generate Automatic Reports.

It is nearly impossible to highlight every aspect in the program through this tutorial, however aftercompleting it you will have a good knowledge of CADPIPE Building Services and how it can help youdesign better, quicker, and more efficiently.

All AutoCAD commands referenced in this tutorial are shown in CAPITAL LETTERS, while allBuilding Services commands are shown in Bold. All system prompts in the tutorial are in italics and yourresponses are shown numbered. In addition, the metric equivalent to an imperial measurement appears inbrackets: (600).

Let’s Begin

To start the tutorial, double click on the CADPIPE icon, or got to Start/Programs/CADPIPE 7.2 -Building Services Imperial. In the AutoCAD Start up dialog box, Click the Browse button.
