AutoCAD: Isometric view

Working in 3D with AutoCAD has its own uniqueness. Because the program starts working in a 2D viewpoint from the top (Top view), i.e., only sees only 2 axes of work, namely X and Y from looking down at the workpiece.

Therefore, if you want to work in 3D with AutoCAD, you will need to change the default view to the view showing the Z axis. making it inconvenient to use in addition, to really work We tend to use repeated angles.

The program therefore increases convenience by adding a tool, the Views group, to meet the needs and increase the speed of work as shown in the Figure 1.

Figure 1

Tool details, this group of Views, the first part will be a 2D view in various aspects consisting of Top, Bottom, Left, Right, Front, Back.

Followed by a 3D Isometric Projection or a technical 3D image that can measure the width, length, height, like a 2D image, consisting of

SW Isometric / SE Isometric / NE Isometric / NW Isometric

You may be wondering, right? Isometric abbreviation for each view? what does it mean Let’s see the description.

Four directions of view

In order for us to communicate with others about the direction of looking at any object, we must find references to be used to achieve the same understanding first, for example, we tell people to look to the right. Everyone will understand the same. And turn to look in their own right direction at the same time, saying that we are looking at a 3D object, therefore referring to what people have the same understanding that is the direction itself.

Suppose we place the workpiece and look down from the top plane. (Top view) indicating the direction will be as shown in Figure 2.

Figure 2

That means that the Isometric abbreviation is the name of each direction that is a 45 degree diagonal view toward the workpiece. I tried to create a 3D part, then go to the Views group tool and select each view to start with.

SE Isometric

SW Isometric

NE Isometric

NW Isometric

It was found that the change of perspective works according to this principle. Can make us change perspectives quickly. But it will be an angle that is already set (preset), always at an angle of 45 degrees with the XY plane. There will be other tools to help, which will be discussed in the next chapter.
