INTRODUCTION & INSTALLATION

WORKING MODEL - FAST AND POWERFUL ENGINEERING ANALYSIS FOR 
DESKTOP PC'S 

Working Model is a powerful tool for engineering analysis, 
animation, and prototyping. It saves time and money in the 
design process by allowing you create and analyze dynamic 
physical systems on the computer prior to building costly 
prototypes. 

OPERATING CONCEPT

The operating concept of Working Model is straight-forward. 
First, define a set of rigid bodies and constraints (e.g., 
motors, springs, and joints) by drawing them with a mouse. Then 
set your system into motion by selecting "RUN" -- there is no 
pre-processing or post-processing. You immediately receive 
accurate results.

With Working Model, you create systems that are driven by 
physical laws. You can test, re-design, and re-test your 
mechanical system, speeding your time to market by seeing which 
designs work better before you build them. Working Model allows 
you to fine-tune simulation parameters. You can define 
controllers to adjust properties of objects. You can create 
meters to plot the data that is taken during a simulation. You 
can design a model in your CAD program and import the data into 
Working Model. You can even use another application such as 
Excel or MATLAB to control your simulations.

DESIGNED WITH EASE-OF-USE IN MIND

Working Model was designed to be an integral tool in the design 
and analysis process for engineers of all types. Its highly 
intuitive interface makes it useful for engineers of all 
levels. An engineer can quickly test the performance of a shock 
absorber with a simple model, or create a highly complex 
dynamic model of an automobile engine. With its high degree of 
accuracy, Working Model can simulate almost any mechanical 
system.

SMART EDITOR

Working Model features the unique Smart Editort. The Smart 
Editor shortens the design process by making it extremely easy 
to build and maintain complex designs as well as check for 
clearances, mechanism functionality, and tolerances. 
Interconnected objects can be moved by simply clicking and 
dragging-the Smart Editor automatically moves each object based 
on existing constraints. 

IMPORT / EXPORT

Working Model includes import/export options. With Working 
Model, users can import CAD drawings in DXF format from popular 
applications such as AutoCAD, CADKEY and Vellum and use them 
immediately in simulations.

INTER-APPLICATION COMMUNICATION

Working Model uses Dynamic Data Exchange (DDE) on Windows and 
Appler Events on Macintosh to communicate with other 
applications during a simulation.   With this feature, users 
can specify physical models of real-life mechanical designs and 
then control them externally through other programs.   For 
example, Microsoftr Excel can be used to calculate control 
signals.   Data from Working Model is sent to the spreadsheet 
which calculates the control signals based on the current state 
of the system. New control information is then received by 
Working Model and used to calculate the next simulation frame.

ABOUT THE DEMONSTRATION VERSION

These demonstration package includes a limited version of Working 
Model along with numerous example files. You will be able to 
build models, simulate their behavior, make measurements and 
interact with systems using the revolutionary Smart Editort. 

Several features, however, have been disabled in the 
demonstration version. In particular, file saving functionality 
has been removed (Save, Save As, Print, Export, Cut, Copy, 
Paste and Duplicate). This version also limits the number of 
measurements and bodies that can be created to one meter and 
five bodies per document.

THE DEMONSTRATION GUIDE & TUTORIAL

The guide will provide you with information you will need to 
evaluate Working Model. It covers the Working Model tool 
palette, its menus, and a short overview of its powerful 
function language.

Also included are two tutorials that will step you through how 
Working Model can be used to analyze real-world problems. The 
tutorials will show you how to build and analyze a mechanism 
and import geometries from a CAD file.

SYSTEM REQUIREMENTS

Working Model versions are available for both Macintosh and 
Windows personal computers. The following system configurations 
are needed to run Working Model:

Windows: A 486 microprocessor or better is required, Windows 
version 3.1 or greater, minimum of 8 megabytes of RAM and 8 
megabytes of available hard disk space. More than 8MB of memory 
is strongly recommended for optimum performance. We also 
recommend a floating-point math co-processor.

Macintosh: A 68020-based computer or higher (Mac II or above) 
is required. Macintosh Plus, SE, Portable, Classic and 
Powerbook 100 are not supported. Working Model requires System 
7 or later, approximately 8 megabytes of RAM and 8 megabytes of 
available hard drive space. A floating-point math co-processor 
is highly recommended. Working Model is compatible with 
PowerPC-based Macintosh computers.

INSTALLATION

The demonstration disk contains an automatic installer. To 
install: On Macintosh: simply double-click on the icon named 
Double-Click Me to Install.

On Windows: run SETUP from within Windows.
