Dassault to develop a new generation of computer-aided "The 3DEXPERIENCE Company", is a European multinational software company that develops 3D design, CAD/CAM software.

1. Solid work modelling

2.  INTRODUCTION:-
• Computer-aided design (CAD) is the use of computer systems to aid in the creation,
modification, analysis, aor optimization of a design.
• In mechanical design it is known as mechanical design automation (MDA) or
computer-aided drafting (CAD)

3.  Commercial Software's
 Autodesk AutoCAD
 Autodesk Inventor
 Dassault CATIA
 Dassault SolidWorks
 PTC Pro/ENGINEER
 The Importance of CAD Models in Manufacturing:-
• Before CAD, designers used paper, pencils, rulers, compasses, and other tools to go about
their drafting. It was cumbersome, time consuming, and a nuisance at times especially when
there were changes being made to the design.
• During the 1960s CAD was eventually developed originally for the purpose of designing
automobiles.
• After great success, the technology spread to other sectors in the manufacturing industry,
and soon reached the electronics and aerospace industry.

5.  Dassault Systems: 3D Software Company
• Dassault to develop a new generation of computer-aided "The 3DEXPERIENCE
Company", is a European multinational software company that develops 3D design,
CAD/CAM software.
• Dassault Group created in 1981 by Avions Marcel
• 1997: Dassault Systems acquired SolidWorks, a developer of mechanical design
solutions

6.  SolidWorks:-
• SOLIDWORKS is a solid modeling computer-aided
design (CAD) computer program. SolidWorks is
published by Dassault Systems.
• SolidWorks Corporation was founded in
December 1993 by Massachusetts Institute of
Technology graduate Jon Hirschtick.
• SolidWorks released its first product
SOLIDWORKS 95, in November 1995.
• According to the publisher, over two million
engineers and designers at more than 165,000
companies were using SolidWorks as of 2013.

12. Dimension constraints
 Define size
 Define location
Needs more information to control the
geometry
 Sketch can have three states
• Under defined
• Fully defined
• Over defined
o The color blue: means under defined

13. oBlack color: indicates fully defined
Solid work has all the information it need for the geometry.

14. oOver defined
 Solid work has too much information and is confused
Yellow :- indicates over defined
