Chapter 28. Drawing in 3D in AutoCAD > Using Object Snaps and Point Filters

Using Object Snaps and Point Filters

Drawing a line in three dimensions is relatively easy if you type in the coordinates for the end points of the line, rather than picking those points with a mouse. However, typing in points is not overly intuitive and can become tedious very quickly. To get around this, you need to make use of AutoCAD’s drawing aids—in particular, object snaps and point filters.

Object Snaps

As you already know, an object snap is used to accurately input a point based upon an existing piece of geometry. Using object snap modes makes it easy to draw a line from the endpoint of one line to the endpoint of another. When you consider this concept from a three-dimensional perspective, object snaps become almost critical to the drawing process.
