Welcome to the WORLD of AutoCAD

Who is Mr. AutoCAD?

The Word AutoCAD is made up of two words “Auto(logo of company)”and CAD “(computer aided design)”.

Engineering Designing Software.• 2D and 3D computer-aided drafting software.

Useful for Mechanical, Civil and Architectural Fields.

Use to Create Blueprints, Floor Plans, 3D models, and Detailed Construction Drawings and Documents.

Initial CAD Software

• Designed to take basic geometric shapes and manipulate them into a specific design.

• Launched first in 1957 by General Motors and other in 1960 by McDonnell Douglas Automation Company.

Difference Between CAD & AutoCAD

AutoCAD Software

• Designed to take complex and detailed designs.

• Developed by Autodesk,

Inc., in 1982, to aid programmers in all aspects of 2D and 3D design.

LAYERS and LAYER PROPERTIES

• The concept of Layers is very important in AutoCAD and the correct use of layers can make your drawing much easier to work with. Basically, layers are the computer equivalent of tracing overlays on a drawing board. However, layers are much more powerful because you can have many layers in a single drawing and you can control the visibility, color and linetype of layers independently.

This makes working with very complicated drawings much more efficient. Layers are effectively a way of ordering your drawing.

• Write LA on Command Line.
