- Click to select the lower curved face as shown in the following image.
As you select faces, the preview shows the model state that results by unrolling the selection.
- In this exercise, we straighten the tube completely. Click the upper curved face (not the preview graphic) to select the second rolled face.
Once the second rolled face is selected, the model again previews the unroll results.
- Click Apply in the Unfold dialog box to straighten the model as shown in the preview and to reset the dialog box for the next round of unfolds.
Next, you unfold two of the 90 degree bends which form the square tube.
