Learning how to use Computer Aided Design (CAD) is more than a challenge for a lot of the population. In the era of website builders that take the need for programming knowledge out of the picture, those who lack technological savvy are becoming even more allergic to learning the ins and outs of computing. CAD is not something that can be learned in a short space of time but it is of fundamental importance when it comes to designing projects and coming up with construction plans. A CAD system is a combination of hardware and software which enables architects and engineers to design objects like airplanes. CAD is used to create 2D and 3D objects along with additional details.

Drawing Tools
Thankfully, AutoCAD is here to help and there are a number of relatively straightforward tips for you to follow. The first thing to do is become comfortable with the interface. Become familiar with the various drawing tools and open a sample file. It’s very important to get to grips with the navigation tools as this simplifies things when you start drawing. The drawing tools are pretty easy to remember. The line tool creates lines, rectangle tool creates rectangles and so on. Each tool has various steps however which is why you also need mastery of the command tool.

The AutoCAD tells you what to do after you have activated the tools. It’s up to you to specify the first point. Click in the drawing area and AutoCAD will ask you to specify the next point. For example, if you wanted to draw a circle, you enter the command: ARC and specify the starting point of the arc or the center C point. Once you have activated a circle, AutoCAD will ask you to specify a starting point but you could specify a center point instead by entering ‘C’.

Being Precise
Familiarity with the drawing tools is just a starting point. The next step is precise input. This involves a command of geometry but it will help you to create more precise drawings. Modify tools are not difficult to master either. Like the drawing tools, each symbol is representative of what the tool does. You should also press F1 after activating a tool as this gives you a help menu with the related topic already there. Object selection is the next step after learning modify tools.

At this stage, you should be able to create reasonable drawings but it’s the ability to master annotation that defines your efforts. Annotation refers to non-geometrical elements of the drawing such as dimensions and tables. You can choose between the various styles on offer to decide what the annotation of your drawing looks like. This can be a tricky time because you may become confused by the wide variety of options. For example, you may think a certain sized text looks perfect when in actual fact, it’s unreadable in its final form.

Once you have become used to following the above steps, you should have an excellent knowledge of CAD training and will hopefully be able to produce drawings of stunning quality.
