Windows Based CAD Systems

• PC Hardware has become incredibly fast and powerful.

• Software developers have begun Producing good software

products taking advantage of the MS-windows graphics

environment since 1996.

Windows Based CAD Systems..Common Features

• Use the functions provided by MS windows 2000 look similar to other MS Programs users feel comfortable, learn to use them fast.

• Have Object Linking and Embedding capabilities

….. More ……

Windows Based CAD Systems..Common Features

• Use “Component technology” i., e; the best key software elements are selected from among available software.

• Employ Object-Oriented technology: guides the user to give necessary input, save memory ( all data

associated with a part stored in one file.

….. More ……

Windows Based CAD Systems..Common Features

The only difference is whether the constraints are solved sequentially or simultaneously.

….. More ……

• Provides capability of either ‘parametric modeling’ or ‘variational modeling’.

both approaches allow a user to define

a shape by using constraints instead of manipulating the shapes of elements directly.

Windows Based CAD Systems..Common Features

• Internet support which allows remotely located users to communicate regarding the same part while marking up the part model on their screens.
