Now, you’ll begin to draw the inside of the tub, starting with the narrow end. You’ll use your offset
lines as references to construct the arcs that make up the tub. Also in this exercise, you’ll set up some
of the Osnap tools to be available automatically whenever AutoCAD expects a point selection. Here
are the steps:
1. Choose Tools  Drafting Settings, and click the Object Snap tab. You can also type Os↵ or rightclick
the Osnap button on the status bar and then choose Settings from the shortcut menu.
2. Click the Clear All button to turn off any options that may be selected.
TIP Look at the graphic symbols next to each of the Osnap options in the Object Snap tab. These are
the Osnap markers that appear in your drawing as you select Osnap points. Each Osnap option has
its own marker symbol. As you use the osnaps, you’ll become more familiar with how they work.
3. Click the Endpoint, Midpoint, and Intersection check boxes so that a check mark appears in
each box, and make sure the Object Snap On option is selected. Click OK.



You’ve just set up the Endpoint, Midpoint, and Intersection osnaps to be on by default. This is
called a Running Osnap; AutoCAD automatically selects the nearest Osnap point without your
intervention. Now, let’s see how a Running Osnap works:
1. In the 2D Draw control panel, click the Arc tool or type a↵. See Figure 3.9 for other Arc
options available when you choose Draw  Arc.
2. For the first point of the arc, move the cursor toward the intersection of the two lines, as indicated
in the top image in Figure 3.10. Notice that the Intersection Osnap marker appears on
the intersection.



3. With the Intersection Osnap marker on the desired intersection, click the left mouse button.
4. Move the cursor to the midpoint of the second horizontal line near the top. When the Midpoint
Osnap marker appears at the midpoint of the line, click the left mouse button.



5. Use the Intersection Osnap marker to locate and select the intersection of the two lines at the
upper-left side of the bathtub.
