Creating Tubes with the Sweep Tool
One more element needs to be taken care of before your chair is complete. The legs are currently
simple lines with sharp corners. In this section, you'll learn how you can convert lines into 3D
tubes. To make it more interesting, you'll add rounded corners to the legs.
Start by rounding the corners on the lines you've created for the legs:
1.
Use the Explode tool near the middle of the Tool Sets palette to explode the 3D polyline
legs into simple lines.
2.
Choose the Fillet tool from the Tool Sets palette, or enter
F
↵ at the Command prompt.
3.
Enter
R
↵ to set the fi llet radius.
4.
Enter
2
↵ for the radius. Metric users should enter
5
↵
5.
Enter
M
↵ to select multiple pairs of lines, and then select pairs of lines to fi llet their
corners.
6.
When all the corners are rounded, press ↵ to exit the Fillet command.
7.
Delete the two polyline splines you used to form the sides of the seat. Your drawing
should look like Figure 20.41.
The chair is almost complete, but the legs are just wireframes. Next you'll give them some
thickness by turning them into tubes. Start by creating a set of circles. You'll use the circles to
defi ne the diameter of the tubes:
1.
Draw a
3
⁄
8
˝ (19 mm) radius circle in the location shown in Figure 20.41. Don't worry if your
location is a little off; the placement of the circle isn't important.
2.
Use the Array command to make 15 copies of the circle. In Figure 20.41, a 4-
×
-4 array is
used with the default 1˝ spacing. Metric users should use a spacing of about 30 mm.
