We can’t create spheres in the same way that we create cubes, but we can create a shape that appears to be a sphere. You can play with the opacity and color of the sides and/or add virtual lights to give the shape some definition. Then parent each of the sides to the null object and use it to position your cube in 3D space. Create a null (from the top menu, Layer>New>Null Object) and turn on its 3D property in the timeline window. You can do this by parenting the sides to a 3D null object. Once you have your cube or box created, you may want to move it around your scene. If your layer needs to move forward by 250 pixels, you can click on number you want to change and type “+250” after it. You can make this process more streamlined by actually doing simple math within the timeline. If, for example, you want to create a cube with sides that are 500 pixels, each side needs to be 500 pixels away from its opposite side. Switch the layers to 3D and adjust the orientation (or rotation) and position of each side so that they line up. Construct your shape using solids – when you create a new solid, you can specify the size, so you can create a cube fairly quickly by creating six square solids (one for each side of the cube). Making a 3D cube in After Effects is quite simple, although the process can be a bit tedious. We can, however, create or simulate simple 3D shapes such as cubes and spheres. As I previously mentioned, After Effects can be used to place 2D layers in 3D space, but it can’t be used for advanced 3D modeling.
