From Basics to Mastering AutoCAD

Posted by: Hi-Tech | Posted on: February 7th, 2013

CAD (Computer Aided Designing) Software can be used for creating 2-D drawings and 3-D Models for visualization of structurally viable Modeling Curves, Surfaces, Solids, and Assemblies etc. When any one value in these plans and construction drawings is changed, all the other interdependent values automatically change.

CAD and CAM: CAD is also known as CADD (Computer Aided Design and Drafting). Advanced CAD programs offer features such as animation and rendering of the design.

Computer Aided Manufacturing (CAM)is done after your CAD Model is ready.

Learning AutoCAD: The CAD Applications from Autodesk Inc. are widely used and their DWG format is quite common.CAD Data is exchanged using DXF format.

First and foremost you have to decide as to what project you are going to use AutoCAD for. There are specialized programs pertaining to architectural, civil, aeronautical, mechanical or electrical drawing.

Have basic knowledge initially so that there is less confusion. Get familiar with the Interface. Try to open any drawing or you can start with a sample file. To learn various navigation tools, try to navigate through your drawing by zooming in, zooming out etc. which will help later while drawing. You can create a new drawing using a new template.

For instance, if you activate a drawing tool, like a line, specify first point and after clicking in the drawing area, specify next point. You don’t have to worry about precision initially.

Once you snap to geometry, you will be able to draw precisely. Modify tools are much like drawing tools. Object selection, annotation and styles can be used to modify your drawings. So, the styles will define how your annotations will look like. For this, you can use annotation scale or simply use a template that already has all the styles.

You can create a library for some objects like symbols and standard parts and manage them as reusable content. Learn about creating, modifying, using blocks and pallets. Always compile your drawings in your templates. Make use of cad standard as it will be convenient for everyone working with you.

Divide your design into separate files so that each of these can be opened separately and you can work simultaneously with your partners.

The units (e.g. inches, mm or feet) can be selected by using UNITS command.

Using short cuts will make your work easier. For instance, by pressing ENTER key, you can repeat your last command.

Save your work periodically by clicking on the “A” icon and then selecting ”Save”(Ctrl+S).

If you intend to plot your drawings, click on “A” icon and select ”print”. Do ”preview” your drawing. For ending the program, click on ”A” then ”Exit AutoCAD”.

Practising regularly and using the right tools will gradually make you conversant with AutoCAD.
