Chapter 18
Drawing Curves
So far in this book, you've been using basic lines, arcs, and circles to create your drawings in the Autodesk® AutoCAD® software. Now it's time to add polylines and spline curves to your repertoire. Polylines offer many options for creating forms, including solid fills and free‐form curved lines. Spline curves are perfect for drawing accurate and smooth nonlinear objects.
Introducing Polylines
Polylines are like composite line segments and arcs. A polyline may look like a series of line segments, but it acts like a single object. This characteristic makes polylines useful for a variety of applications, as you'll see in the upcoming exercises.
Drawing a Polyline
First, to learn about the polyline, you'll begin a drawing of the top view of the joint shown in Figure 18...
