Lesson 11: Guidelines and Splines
Now we're moving into the more advanced aspects of basic AutoCAD. If you're not comfortable with the first two parts of our text ( AutoCAD 2005: One Step at a Time Part I ), it might be a good idea to spend a couple hours going over the less familiar portions before continuing.
Lesson 11 will familiarize you with AutoCAD's version of guidelines a tool missing through the first twelve releases and welcomed by many when it first appeared. We'll also cover the use of the Spline command to draw contour lines like those found on topographical maps.
11.1 Contour Lines with the Spline Command
In Lesson 8 (Section II), we studied polylines and the PEdit command. I'm sure you found them as complicated as most people do the first time.
We learned how to make a spline (a contour line) from a polyline using the PEdit command. Here we'll see how we can draw a spline more easily and in a way that shows a contour line as you draw it. Additionally, you'll see that a spline drawn using the Spline command takes up much less drawing memory and thus reduces the size of your drawing.
The command sequence for the Spline command is
-
Command: spline (or spl )

Specify first point or [Object]: [pick the starting point]
-
Specify next point: [pick the second point]
Specify next point or [Close/Fit tolerance]
