    Rotating 3D Object

      I am creating an animation of a screw with a key on the top of it rotating. The only part of the screw that will appear to rotate will be the key on the top moving around the screw. I clicked on the 3D box to get the z axis rotation. I then changed the x axis rotation to 360 degrees. It rotates but when it does it remains 2D. Is there a way to keep the shape and fill of the screw as it rotates? Sorry if this is confusing. Hope someone can help.

          3D in AE is actually 2.5d (billboards). They have no depth. If you want a 3d object with depth, you need to model it and render it rotating, or import via ps:e cs4 and ae cs4, or 3rd party plugin (3d invig).

            As David said: "True 3D" in AE is only possible by using Photoshop Live 3D in CS4. Everything else labeled 3D in AE is fake or at least specific to plugins using their own little internal 3D universes Depending on what version of AE you use and what additional plugins you have, you could possibly retain the illusion by e.g. using a cylinder created from 3D layers for the head and body and then "texturing" it in combination with animated layer styles and the wrench by using Jerzy's CE Shape Extruder (www.maltaannon.com), but that mostly covers it...

              Can you explain how I would create the illusion? How do I create a cylinder? I know how to make it a 3d layer but not sure how to do a cylinder, just a shape. If you could explain what you mean by texturing it with animated layer styles that would be great. Sorry for asking so much. Hope you can help me. :)

                Apply the CC Cylinder effect to a 2D layer.
                Effect > Perspective > CC Cylinder

                  Lauren, I've re-uploaded my 3D-layer primitives setups to my website (sorry that the latter is in such bad shape these days, I simply do not find enough time for the next step in its evolution). They are all rigged with expressions and only require you to duplicate layers or replace the solids. Maybe this gives you some ideas. Also do not forget that pre-CS3 the 3D Assistants Lite were included in AE which also would allow you to create such shapes.

                    Steve- I don't have the CC Cylinder effect. I am using Adobe After Effects 5.5. Was it not offered in that version? Any other suggestions?

                    Mylenium- thanks for all the links. I could only get the first one to work. There is no shape in the file. It just looks like filters and effects but no shape or anything showing up on the preview. ???

                        The "Controller" at the bottom controls the radius and so on. You need to clone the "Side" layer above it to see a cylinder. You can replace this layer with anything you like. The objects will look flat at first, because there are no 3D lights in the scene, so add some as you need.

                          Hey Lauren.
                          I don't remember if the Cycore effects shipped with 5.5.
                          If they did, they were probably shipped as a separate installer (didn't install automatically with AE). In the more recent versions of AE, the Cycore effects have been absorbed into the Professional version, and install automatically with the software. You may want to check your install disk to see if you have a separate installer for the plug-in package. Otherwise, I'm sure Mylenium's links will do you justice.

                            Cycore FX (CC) weren't included with AE 5.5. They were introduced with AE 6.5.

                            They can be purchased directly from Cycore as well, but probably wouldn't work with AE 5.5 anyway, sorry.

                              Mylenium, thank you VERY much for providing these primitives. Would have saved me hours of screwing around many months ago an a couple of terrible rojects form hell but I've got them now.
                              Oooh, got a sphere?

                                  Mylenium- I am just now getting to your cylinder project and trying to substitute your "side" layers with mine. I am not a pro at After Effects (obviously) Is there any way you can walk me through the steps of what to do with your project and how I can take my layer (from another project) and make it 3D? I just used your first file (cylinder). Thanks so much!!!!

                                    Import the project into the cylinder project and then Alt+drag the layers onto the solids in the timeline. The width of the elements is determined by the calculations, so the more layers you have, the thinner they get. You may turn this behavior off by disabling the scale expression. Beyond that it should be pretty straightforward.

                                      I have gotten as far as replacing the layers. I have a flat cylinder (which looks like a rectangle). I replaced the first 36 layers. Am I supposed to replace the bottom two layers with the same file of the rectangle or do I need to somehow create a circle to fit on the top and bottom. I would love to send you the old animation so you can see exactly what I am trying to do. Is there a way to upload that or email it to you? Sorry I'm being such a pain, I just really need to figure this out and I'm about to quit.

                                        You can send any examples and links to mylenium|-|at|-|mylenium.de. I would love to help and adjust the project for you, but I no longer have 5.5 on my systems, so this would be a one-way trip.

                                          did you get my email? I sent it around 3:00 today to mylenium@mylenium.de
                                          is that correct?

                                            Your mail has arrived safely and I will take care of the matter. Just be aware that, as I'm in Germany, there is a considerable timezone shift and actually when you are at the height of the afternoon, I usually go to bed, so naturally there are delays. ;-)
