Reference and Constraints with AutoCAD - Section 3

13.1.4 Zoom zoom in and out

The “Enlarge” and “Reduce” tools are the simplest to use, but also the most limited. When we press “Enlarge”, the objects on the screen are redrawed at twice their current size without further ado and respecting the existing frame.
Needless to say, “Reduce” presents objects at half the current size and also without changing the frame.

13.1.5 Extension and All

In many cases we get into the details of the drawing and use the different zoom tools to improve the visualization of different parts of our work. But there always comes a time when we need, once again, a total view of the result. To do this we can use the "Extension" and "All" zoom tools. The difference between one and the other is that “Extension” zooms in on the screen showing all the drawn objects. While "All" shows the area defined by the limits of the drawing, regardless of whether the drawing is too small for the limits.

13.1.6 Object

“Object Zoom” or “Enlarge Object” is a tool whose operation the reader can easily guess. It involves activating it and then selecting one or more objects on the screen. At the end of the selection with the "ENTER" key, the selected object(s) will take up as much space as possible on the screen.

13.2 Back and Forward

This pair of tools in the “2D Navigate” section simply allow us to move between the views established by any Zoom and/or Pan tool, which implies that Autocad registers them in memory to facilitate navigation.

13.3 Additional Navigation Tools

The navigation bar, which by default is to the right of the drawing area, has three more tools that we will simply mention here, but we will use it more extensively when studying the 3D working environment. It is the navigation wheel or SteeringWheel, the Orbit command and ShowMotion.
The navigation wheel allows you to move very nimbly in a drawing of 3 dimensions once the user gets used to its use. However, it has integrated several versions of it, including a basic version for navigation 2D.

For its part, Orbit is a command clearly designed for 3D models, despite the fact that it is not only found in this toolbar, but also in the “Navigate 2D” section, so it works in this environment anyway. . I invite you to use it, subject to the fact that we will study it in detail later.
