Introduction to Drawing in AutoCAD
Being a computer-assisted drawing software program, AutoCAD allows us to create drawings with precision in both 2D and 3D. In this article, we will focus on the basic functions to make construction designs and manufacture objects. By learning the main functions of AutoCAD, you can start creating scale drawings for uses as diverse as manufacturing equipment, planning construction projects, and electrical circuits.
Tips on the AutoCAD Toolbar
The first thing you should do is familiarize yourself with the AutoCAD interface. This is accompanied by a toolbar that has tools for drawing, modification, and controls.
Before anything else, make sure you use the right units of measurement. You can go to the big A in the upper left corner to open the AutoCAD menu. Select “Drawing Utilities” and “Units.” There you have the option of choosing measurements based on the metric or imperial system. Thus, you can use the unit that suits you best, meters, feet, millimeters, etc. The other icons on the toolbar are organized in a simple way, all being related to similar functions.
After installing AutoCAD, you will notice that there are not many toolbars that you can activate.
It is important to take into account that it is problematic to have all those bars together. That is why you must select those you require for your project.
Avoid having all toolbars activated at the same time since that can saturate your screen. Focus on knowing all of them but try to have the least possible.
You can activate the bars through any other bar that has already been activated. Go to your context menu with the right-click button, right in the wide part of the bar. There you will see the names of all available tools. Once this is done, choose the ones you want to activate or deactivate.
On the other hand, when you want to deactivate a toolbar, you simply need to follow the previous method and choose those that you will no longer use. Some of the tools on this list include rendering, maps, inserting, layers, etc.
Taking Accuracy Into Account
When using AutoCAD, it is important to pay full attention to design accuracy. As soon as you use AutoCAD, you will realize t
hat many of the tools require start and end points. In some cases, you can specify these points just by clicking. However, in other cases, you must specify points by using coordinates. This is crucial, especially for professionals such as architects and engineers, who rely heavily on precision.
This is why you should familiarize yourself with the three AutoCAD coordinate systems:
- Absolute coordinates are the entry points specified when using standard Cartesian coordinates.
- Relative coordinates can be entered later and require specification of the coordinate that follows, and that must be relative to the first point.
- Polar coordinates are used when you need to draw the next point at a specific angle and/or distance.
The Use of Basic Geometry
AutoCAD has a great variety of geometric shapes in 2D. These objects range from lines to circles and shaded areas.
Here is a list of the main ones:
- The Line command draws a straight line from point A to point B.
- The Circle command draws a circle based on a radius and a center point.
- A polyline is a connected sequence of line or arc segments created as a single object.
- The Rectangle command is used to draw a rectangle with vertical and horizontal sides.
- A shadow is an object that covers an area with a pattern of lines, dots, shapes, solid fill color, or gradient fill. When you choose this command, you can choose from a variety of shading patterns.
Likewise, we have some slightly more advanced tools such as the following:
- The Cloud command, which you can use to highlight some elements of our drawing and, therefore, make revisions.
- Elliptical Arc Tool, used to make the arc.
- Ellipse command, used to create an ellipse in the program from the command line.
- Auxiliary lines, which are widely used because almost all drawings begin marking the List (Model) space of the future part, and then segments, arcs, and other objects surrounding it.
When you know the basic drawing tools, the next logical step is the modification tools. This includes deleting and splicing sections. So, if you are not satisfied with how the drawing looks, you can use some tools to improve it.
AutoCAD has a number of options that include “move,” “copy,” “rotate,” and “delete.” All these are self-explanatory.
Furthermore, AutoCAD offers a series of commands that allow you to work more easily:
- REG: Allows you to create region geometry.
- CO: Copy objects.
- ARRAY: Create rectangular, polar, or path matrices.
- TR: Trim a geometry.
- OP: Open settings window.
- SC: Change the scale.
- B: Make a block.
- I: Insert existing block.
- ST: Open the text style window.
- X: Explode objects.
- F: Add rounded corners to sharp edges of any firm.
- CHA: Similar to the previous one, add slanted edges to sharp corners.
- LA: Open the layer properties management palette.
Without a doubt, knowing AutoCAD is a long and challenging process. Although it is initially difficult to use AutoCAD, the practice will help you improve your skills. In this short article, we have covered the most basic AutoCAD tools. Once you have understood these basic concepts, experiment a little and get to know the other tools.
