This document introduces AutoCAD software. It defines AutoCAD as a software program used to design 2D and 3D images that provides tools for detailed product design and layout. AutoCAD can be used by designers to visualize imaginary product views and make changes before finalizing a design. It offers flexibility for implementing ideas and presenting designs to clients. AutoCAD is popular among architects, engineers, and builders for developing project layouts. It replaces traditional drafting methods and offers benefits like time savings, increased productivity, and quick 3D prototyping.

1. Introduction of AutoCAD

2. WHAT IS AutoCAD
AutoCAD is a software program built to design and shape
the 2-D and 3-D images. It provides the tools by which a
detail design of the product can be done. It also has the
option to create detailed design layout, which can be
automatically drawn by using source model.
OR
Another definition for it would be the use of computer
technology to aid in the design and particularly the
drafting of a part or product. It is both visual (or drawing)
and symbol-based method of communication whose
conventions are particular to a specific technical field.

3. USES OF AutoCAD
AutoCAD can be used by the designer to visualize
the imaginary view of the product on a computer
system. In AutoCAD, it is possible by the drafter to
make the changes in the product before it gets
finalized for design. It also gives the freedom for the
designer to implement their various ideas and
represent them to the suppliers or their clients.
AutoCAD is more popular among the architects,
engineers and builders for developing their project
layouts.

4. Benefits of Using AutoCAD
AutoCAD has replaced the traditional method of
drafting and designing which was made by pencil,
drafting boards, triangles and compass with just a set
of a computer program. The benefits are immense like:
• Saves time and helps to increase the productivity.
• It helps to streamline your design and documentation
workflow.
• Physical ‘3D’ prototype of the design can be quickly
created by using AutoCAD.
• Tedious work of drafting can be done easily and you
can design and re-design the product in short span of
time.

5. Features Under AutoCAD 2D
Drafting
• Drawings simple Sketches
• Line & Line type, Arc, Circle, Polygon, Draw & redraw & Modify
• Co-ordinates System
• Limits, Units
• Dimension, Layer
• Text, block, import & Export
• Complete 2D CAD Drawings
• Overview of Plotting etc.
Productivity Tools
• Group, Block & W-block, Insert, m-slide ,V-slide, Run
• Script filter, external reference, view port & layout
• M – insert , OLE object, Plots, DB-connect, e-transmit public to web
attribute.

6. Basic Shortcut of AutoCAD
 F3 for Object Snap - When set on, an osnap icon appears at the cursor
pick box .
 F6 for Allow/Disallow Dynamic UCS - Used when constructing 3D solid
models.
 F7 for Grid Display -When set on, a series of grid points appears in the
drawing area .
 F8 for Ortho Mode - When set on, lines etc. can only be drawn vertically
or horizontally.
 F9 for Snap Mode - When snap is on, the cursor under mouse control can
only be moved in jumps from one snap point to another.
 F10 for Polar Tracking - When set on, a small tip appears showing the
direction and length of lines etc. in degrees and units.
 F12 for Dynamic Input - When set on, the x, y coordinates and prompts
show when the cursor hairs are moved.
 Show/Hide Lineweight : when set on, lineweights show on screen.When
set off, lineweights only show in plotted/printed drawings.
