The top level is occupied by IGES (Initial Graphics Exchange System). … This standard governs the exchange of CAD objects between application specific databases, allowing an object created on one system to be transferred to another (otherwise incompatible) CAD system for processing.
What are graphic standards?
Graphic standards provide a sound, flexible structure for using logos, color and typography. Consistent brand application is essential. The logos must appear the same in every instance. They must have the proper color selections, be in the proper proportions and be used in appropriate contexts.
What is the need of graphic standards in CAD?
Standards for computer graphics-Need for graphic standards • Need for portability of the geometric model among different hardware platforms. Exchange drawing database among software packages. Need for exchanging graphic data between different computer system.
What are the types of standard used in CAD system?
AEC (Architecture Engineering and Construction) standards
- CAD layer standards.
- Text and dimension.
- File naming standards.
- Model-based definition.
- Geometry quality.
What is CAD CAM exchange?
CAD data exchange is a modality of data exchange used to translate data between different Computer-aided design (CAD) authoring systems or between CAD and other downstream CAx systems. Many companies use different CAD systems internally and exchange CAD data with suppliers, customers and subcontractors.
What is graphic standardization?
Agreed specifications which define the common interfaces between computer systems or subsystems. Standards, if they are generally observed by manufacturers, promote the interchangeability of computer equipment.
What are the types of computer graphics?
Types of Computer Graphics
- Raster Graphics: In raster graphics pixels are used for an image to be drawn. It is also known as a bitmap image in which a sequence of image is into smaller pixels. …
- Vector Graphics: In vector graphics, mathematical formulae are used to draw different types of shapes, lines, objects and so on.
What is full form of phigs?
(Programmer’s Hierarchical Interactive Graphics Standard) A graphics system and language used to create 2D and 3D images. Like the GKS standard, PHIGS is a device-independent interface between the application program and the graphics subsystem.
How many types of graphical interfacing standards are there?
There are three de facto GUI-standards that are the basis for all GUIs. This section reviews the common definition of GUIs, the history of GUI development, and GUI standards in the marketplace. A GUI is a type of computer human interface on a computer.
What is GKS?
GKS (the Graphical Kernel System) is an ANSI and ISO standard. GKS standardizes two-dimensional graphics functionality at a relatively low level. The primary purposes of the standard are: … To aid in the understanding of graphics methods by application programmers.
What are CAD standards and its need?
According to Wikipedia, CAD Standards are “a set of guidelines for the way Computer-aided design (CAD) drawings should appear, to improve productivity and interchange of CAD documents between different offices and CAD programs, especially in architecture and engineering.” And that’s exactly it.
What are CAD requirements?
- Operating System: Microsoft Windows 10 (64-bit only), 8.1 (32-bit & 64-bit), or 7 SP1 (32-bit & 64-bit)
- Processor: 2.5 GHz (3+ GHz recommended)
- Memory: 8 GB (16GB recommended)
- Disk space: 6.0 GB.

Which is better IGES or STEP?
Why is STEP better than IGES? STEP is newer technology, where IGES which is older 1990’s technology, that has not been updated in over 20 years. STEP files tend to be solid models, where IGES files are more often surface models, which could have gaps and missing faces.
