dialog also displays an illustration that offers a graphical description of the
selected option:
A - Chord Tolerance This option calculates the number and size of
facets based on a tolerance for how far the flat face can deviate from
the ideal curve.
B - Facet Angle This is a limit on how much the facet can deviate
from the adjacent facet, measured in degrees.
C - Facet Distance Use this option if you want to limit the maximum
width of the facets.
Bend Radius Instead of having a Bend tab in the dialog, the opportunity to
override the default bend radius of the active sheet metal rule appears on the
Shape tab.
Preview Many dialogs include a pair of glasses. When this option is checked,
Inventor previews the geometry as you saw it do in Chapter 2. When you're
doing complex assembly functions or creating diffi cult features on a system with
limited memory or graphics capability, you may want to disable this option to
improve performance.
Now, let's put it to the test and see how it does with your sketches:
1. Restore the home view.
2. Start the Lofted Flange tool, found on the Create panel.
3. Without changing any options, select the Square Sketch for Profi le 1.
4. The program dialog is ready for Profi le 2. Pick the circle. The preview
shows the faceted transition.
5. Change the value of Chord Tolerance from 0.1in to 0.5in. See
Figure 3.5.
6. Switch the Output value to Die Formed.
7. Click OK to create the lofted fl ange.
8. Orbit around your part to see how it's assembled.
9. Select the Back face on the ViewCube. Use the rotation arrows to
properly show the word Back if need be.
10. Right-click the ViewCube, and select Set Current View as Front, as
shown in Figure 3.6.
