In fact, you not only can zoom and pan in the drawing but also, in most kinds of drawings, you must zoom and pan frequently to be able to draw and edit effectively.

Why do you need to pan and zoom often? For starters, though many architectural drawings plot out at 3 feet by 2 feet, you probably aren’t fortunate enough to own a monitor of that size with sufficient resolution to be able to see every little detail.

Early releases of AutoCAD came with a sample drawing of the solar system done to scale. When first opened, it showed circles for each planet’s orbit. Zooming in revealed the moon’s orbit around Earth, then a crater on the moon, then the lunar landing module, and finally writing on the plaque mounted on a leg of the lunar lander.

In addition, technical drawings are jam-packed with lines, text, and dimensions. As discussed in ssss1, drawing with precision is essential to following best practices for AutoCAD drawings. Frequent zooming and panning enables you to better see detail, to draw more precisely because you can see what you’re doing, and to edit more quickly, because object selection is easier when the screen isn’t cluttered with objects. This chapter describes the most useful display control features in AutoCAD.
