The Flex Tool: TWIST

1. Start with the vase you created in the previous exercise.

6. The twist axis is shown as a dashed blue line.
7. You can use the triad (three rings) to rotate the twist axis, but you probably don't want to do this.
8. Click on the red trim plane and drag it to apply a twist of about 120 degrees. You can read the twist angle in the parameter box on the left.
9. Click OK to complete the twist action.
10. Edit the feature again and try some other twist values: 180 degrees, and 520 degrees.

The Flex Tool: BEND

1. Create another Flex feature.
   • If you don't have Flex in your Features toolbar, you can add it by selecting Tools from the top pulldown menu, then click on "Customize"; select the "Commands" tab; click on the "Features" menu item; and finally, drag the Flex icon onto the Features toolbar. Then click "OK".
2. Click anywhere on the case.
3. Select the Bending radio button.
4. The bend axis is shown as a dashed red line.
5. Move the bottom trim-plane one third of the way up the vase.
6. Right click on the Triad and select "Move triad to Plane 1" (the bottom plane).
7. Click on the red trim plane and drag it to bend the vase to about 75 degrees.
8. Click OK.
9. If you get a self-intersection error, move the trim plane down or reduce the bend angle.

More Flex Tool

1. Make a new part.
