PREFACE

The Pro/ENGINEER User Guides describe all of Pro/ENGINEER’s functionality and how itis used. They have common structure and style conventions, described below.

The manuals are designed with two purposes in mind:• To help you quickly learn to make productive use of Pro/ENGINEER• To describe the more advanced uses of the system

It has been assumed that you are familiar with your workstation, and have some knowledge ofyour operating system.

Pro/ENGINEER DOCUMENTATION

Documentation is divided into several manuals which together comprise a comprehensive guideto Pro/ENGINEER. Each manual deals with a major function of the software, and you can usu-ally find which manual you need by first looking at the title. If not, there are indices correspond-ing to each book, and there is also a Master Indices that indexes the entire Pro/ENGINEER doc-ument family.

A complete list of Pro/ENGINEER user guides can be found in Chapter 1 of the “Fundamentalsof Pro/ENGINEER”.

USING THESE MANUALS

To find information in the manuals quickly, become familiar with the aids provided:Table of Contents - A Table of Contents is provided at the beginning of each document

with all chapter titles and the section headings of each chapter. Use theTable of Contents to familiarize yourself with the layout of eachdocument.

Labels - Interspersed along the left side of pages are labels. They are forlocating information within a general section of the Guide by quicklyscanning the column.

Bleeding Tabs - Chapter headings, on bleeding tabs, are on the right side of each page.These help you quickly locate a particular chapter of the document.

Indices - Indices containing Pro/ENGINEER commands and keywords areprovided for every document.

Master Indices - A master index of commands and keywords is provided showing thedocument and page number where the item is located.

CONVENTIONS

In order to clarify the discussion of various topics, the following conventions have been em-ployed throughout all the manuals:

Boldface Type indicates a menu option (Part). However, only when the namerefers to the actual option will it appear in bold type.

UPPERCASE Indicates the name of a menu (PART).

Page 4: eleclib.pdf

[Bolt] When you need to enter information using the keyboard, it will appear[between two brackets in courier font likethis] . Type everything between the square brackets exactly asshown.

<CR> Words between the <> symbol indicate the name of a keyboard key.Reference When referencing other sections of the document, it will appear in

italics like this.Emphasis When something is being emphasized, it will appear inbold italics like

this.

NOTE: Important information that should not be overlooked willappear in notes like this.

All mouse clicks assume that the mouse has been configured as right-handed.

COMMON TERMS

There are a few very important terms that are used frequently in the User Guide; they are definedhere. A full glossary of Pro/ENGINEER terms appears in Appendix B of “Fundamentals ofPro/ENGINEER”.

Choose - Select a menu option by placing the arrow cursor on the option, andwhen it is highlighted, pressing the left mouse button.

Mode - An environment in which Pro/ENGINEER allows you to perform acertain group of closely related functions (e.g. Drawing).

Model - A part or an assembly.Object - An assembly, part, drawing, format, layout, case study, sketch, etc.Pick - Select an item on the screen by clicking the left mouse button.
