![]() ![]() If you selected the red arrow, you were translating the cube along the X axis. The technical term for moving an object in a 3D application is translating. If you let go of the left mouse button, you will release the 3D manipulator and the cube stops wherever it happens to be. The cube will follow you along the axis as you move your mouse. Left-click one of the arrows on the 3D manipulator and hold the button down while you drag on the arrow. Select the cube by right-clicking it if it's not already selected. The bottom left corner will also show you the name of the currently selected object. You can see the current orientation of the screen in the bottom left corner of the workspace as a miniature version of the three axes. You may remember the X and Y axes from high school plotting points on a graph 3D applications use those axes plus a third axis, the Z axis, which represents the third dimension and allows us to represent 3D objects using the 2-dimensional surface of the screen. Different applications orient these axes differently, but the meanings remain the same. The colors have a fairly standard definition across 3D applications: red is the X axis, green the Y axis, and Z the blue axis. If you select the other objects, you'll notice that it follows you around, allowing you to move anything in the scene. ![]() ![]() The 3D manipulator is used to transform, or move, rotate, and scale, objects. In the middle of the cube is the 3D manipulator widget it looks like a group of red, green, and blue colored conic arrows radiating at right angles from a white central point with a white ring around it. ![]()
