Introduction of AutoCAD
- 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.
- 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.
- 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.
- 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.
- Basic Shortcut of AutoCAD –
ØF3 for Object Snap – When set on, an osnap icon appears at the cursor pick box .ØF6 for Allow/Disallow Dynamic UCS – Used when constructing 3D solid models.
Ø F7 for Grid Display –When set on, a series of grid points appears in the drawing area .
Ø F8 for Ortho Mode – When set on, lines etc. can only be drawn vertically or horizontally.
ØF9 for Snap Mode – When snap is on, the cursor under mouse control can only be moved in jumps from one snap point to another.
ØF10 for Polar Tracking – When set on, a small tip appears showing the direction and length of lines etc. in degrees and units.
ØF12 for Dynamic Input – When set on, the x, y coordinates and prompts show when the cursor hairs are moved.
ØShow/Hide Lineweight : when set on, lineweights show on screen.When set off, lineweights only show in plotted/printed drawings.
0 – Creates exploded dimensions. There is no association between the various elements of the dimension. The lines, arcs, arrowheads, and text of a dimension are drawn as separate objects.1- Creates non-associative dimension objects. The elements of the dimension are formed into a single object. If the definition point on the object moves, the dimension value is updated.
2 -Creates associative dimension objects. The elements of the dimension are formed into a single object, and one or more definition points of the dimension are coupled with association points on geometric objects. If the association point on the geometric object moves, the dimension location, orientation, and value is updated.
