7.2 Types of Lines

  The linetype of an object can also be changed by choosing it from the corresponding drop-down list in the Properties group on the Home tab, when the object is selected. However, Autocad's initial setup for new drawings only includes a solid line type. So, to begin with, there is not much of ...

7.1 Color

  When we select an object, it is highlighted with small boxes called grips. These boxes help us, among other things, to edit the objects as will be studied in chapter 19. They should be mentioned here because once we have selected one or more objects and, therefore, present “grips”, it is possible to modify their ...

CHAPTER 7: PROPERTIES OF THE OBJECTS

  Each object contains a series of properties that define it, from its geometric characteristics, such as its length or radius, to the position in the Cartesian plane of its key points, among others. Autocad offers three ways in which we can consult the properties of the objects and even modify them. Although this is a topic ...

6.6 Regions

  There is yet another type of composite object that we can create with Autocad. It's about the regions. Regions are closed areas which, due to their shape, have physical properties calculated, such as the center of gravity, so in some cases it will be convenient to use this type of object instead of polylines ...

6.5 Propellers

  Propellers in Autocad are essentially 3D objects that are used to draw springs. In combination with commands to create solid objects, they allow you to draw springs and similar figures. However, in this section dedicated to 2D space, this command is useful for drawing spirals. If the starting radius and the ending radius are equal, then ...

6.4 Washers

  Washers by definition are circular metal pieces with a hole in the center. In Autocad they look like a thick ring, although it is actually made up of two circular arcs with a thickness specified by an internal diameter value and an external diameter value. If the internal diameter is equal to zero, ...

6.3 Clouds

  A revision cloud is nothing more than a closed polyline created by arcs whose purpose is to highlight parts of a drawing on which you want to draw attention quickly and without much concern for the precision of its parts. Among your options we can modify the length of ...

6.2 Splines

  For their part, splines are types of smooth curves that are created based on the method chosen to interpret the points that are indicated on the screen. In Autocad, a spline is defined as a “Non-uniform Rational Bezier-Spline Curve” (NURBS), which means that the curve does not ...

6.1 Polylines

  Polylines are objects made up of line segments, arcs, or a combination of both. And although we can draw independent lines and arcs that have as their starting point the last point of another line or arc, and thus create the same shapes, polylines have the advantage that they all ...

CHAPTER 6: COMPOUND OBJECTS

  We call "compound objects" those objects that we can draw in Autocad but that are more complex than the simple objects reviewed in the sections of the previous chapter. In fact, these are objects that, in some cases, can be defined as a combination of simple objects, since their geometry is a combination of the ...

5.8 Points in object perimeters

  Now let's go back to the topic with which we began this chapter. As you may recall, we create points simply by entering their coordinates on the screen. We also mentioned that with the DDPTYPE command we can select a different point style for display. Now let's look at two more options for creating points on the perimeters of other objects. These points usually ...

5.7 Polygons

  As the reader surely knows, a square is a regular polygon because its four sides measure the same. There are also pentagons, heptagons, octagons, etc. Drawing regular polygons with Autocad is very simple: we must define the center point, then the number of sides that the polygon will have (obviously, the more sides the ...

5.6 Ellipses

  Strictly speaking, an ellipse is a figure that has 2 centers called foci. The sum of the distance from any point of the ellipse to one of the foci, plus the distance from that same point to the other focus, will always be equal to the same sum of any other point of the ellipse. ...

CHAPTER 3: UNITS AND COORDINATES

  We have already mentioned that with Autocad we can make very diverse drawings, from architectural plans of an entire building, to drawings of machinery parts as fine as those of a clock. This imposes the problem of the units of measurement that one drawing or the other requires. While a map can ...

2.12.1 More changes to the interface

  Do you like to experiment? Are you a bold person who likes to manipulate and modify your environment to drastically personalize it? Well, then you should know that Autocad gives you the possibility to modify not only the colors of the program, the size of your cursor and the selection box, as we just mentioned, but ...

2.12 Customizing the Interface

  I'll tell you something that you probably already suspect: the Autocad interface can be adapted in various ways to customize its use. For example, we can modify the right mouse button so that the context menu no longer appears, we can change the size of the cursor or the colors on the screen. However, this is a ...

2.11 Workspaces

  As we explained in section 2.2, in the quick access bar there is a drop-down menu that switches the interface between workspaces. A “Workspace” is actually a set of commands arranged on the ribbon that is oriented towards a specific task. For example, the workspace “2D Drawing…
