SU Fundamentals 10-3 Autofold

0:03 Autofold is a lesser known aspect of the move tool but it comes in handy when needed.

0:10 A few simple examples will show how it works.

0:15 I’ll start by offsetting the tops on these three objects.

0:20 Then, if I try to move those new surfaces, I can only do so in the same plane they were created in.

0:29 We can’t move any of these shapes upward in the blue direction.

0:33 To move these shapes up, would require additional edges to form the surfaces needed.

0:39 For example, on this box I could draw in four more edges to connect the corners.

0:45 Now I can move this rectangle in the blue direction, because the additional edges allow the surfaces to fold.

0:53 Creating these additional edges, so you can move shapes in any direction, is what autofolding with the move tool will do.

1:02 To see this, select the inner circle, then start to move it.

1:08 We can’t find the blue axis but tap the ‘Alt’ key on Windows, or the 'Command’ key on a Mac to toggle auto-folding.

1:17 Now you should be able to find the blue axis and move this circle upward, creating a cone.

1:26 Do this again on our 3rd example, select the inner shape, start moving it...

1:32 ... and tap the ‘Alt’ key on Windows, or the ‘Command’ key on Mac to toggle auto-folding.

1:38 You don’t need to hold the modifier key down, just tap it once to toggle autofold on.. or off.

1:51 Rectangular shapes tend to fold pretty well.

1:54 The more complex your shape is, the more likely the autofold results will be messy, so do keep that in mind.
