First of all, sorry for that title. I really couldn't find something better, how to describe my problem in short.

I've drew a lock, you can see it on image:

enter image description here

I would need to create a frame animation, so the lock will end like this:

enter image description here

So the final animation will be similar like this one: dribbble.com/shots/1141621-Lock-Icon-Animation-GIF

Here's my problem: I cannot draw the "bend" on the top of the lock (the U shape). If I distort it in PS, it's just like a paper, it flips, and there's no thickness of the metal "U". And when it comes to drawing, I don't know the angle in which I have to "bend" the "U" shape correctly, so I can't even do it by hand.

How could I draw it, so the final animation would look like the one I've described?

Thanks.

  • Wow, that's exactly what I need. I don't have Illustrator, but the image given by me in main post is 1:1 (real size which I need). – BlackJack Sep 14 '16 at 18:11
  • Its not that i couldn't do this in Photoshop but its a bit tedious as i need to use a calculator while in illustrator i dont. – joojaa Sep 14 '16 at 18:13
  • I can install free version of Illustrator for this case. – BlackJack Sep 14 '16 at 18:14

Ok, i did this image for fun. Though I used Illustrator, because it felt more handy fr the task at hand (not perfect mind you). Since there is a limited amount of frames. The result can be seen below:

enter image description here

Image 1: after 9 copies and one mirror about the dashed line

This is the process.

  1. Draw the initial shape. I suggest using a grid as we need to align the shapes later.

  2. apply a effect 3d rotate effect on your shape set values to 0 0 0

  3. copy shape. then increment the z axis by say 10 degrees. copy again increment until you have done a 90 degree turn. Note the 90 degree shape has to be hand drawn.

  4. Swap stroke and fill, then expand the shapes. (otherwise the flatness will become visible)

  5. Ungroup all shapes and delete the bounding box.

  6. Swap stroke and fill again

  7. align items on one spot then distrubute them side by side.

  8. mirror about the mirror plane for the next 90 degrees.

all in all it takes about 7-10 minutes to do, yeah there is a faster way to do this but its easy enough to do manually. To export the sequence see this post

If you dont have illustrator you can instead of rotation use a 100*cos(angle) as scaling factor per frame on a path and then stroke later.

  • Thank you. I'll try it once I will get Illustrator working. Hope I will pass through your great step-by-step tutorial without problems (because I'm not much good with Illustrator), but you described it very well so :) – BlackJack Sep 14 '16 at 18:38
  • Got stucked on 3. . Where is Z axis box? I see only X Y W H on the top. – BlackJack Sep 15 '16 at 16:35
  • @BlackJack in the effects palette under the 3d rotate effect. – joojaa Sep 15 '16 at 16:52
