To change the position of an object in three dimensions, select the desired element, click the 3D Object Translate tool, and then use your mouse to change the position.
You can move an object by clicking and dragging anywhere other than the color-coded compass arrows. However, you have more control when you move an object one axis at a time. For example, dragging the red arrow will cause the object to move along the x-axis. You can also hold the Command key (Mac) or Control key (Windows) to constrain dragging along the z-axis.
To reset the object to its initial position, go to the Properties panel, and under "Translation, rotation, and scale", set the translation X, Y, and Z values (the first row) to 0.
Local and Global Translation
When you use the 3D Translate tool in local translation mode
the 3D compass arrows stay aligned to the object you're selecting. When you use the tool in global translation mode
, the arrows stay aligned to the stage. To choose your translation mode, select local translation
or global translation
in the tool options bar. You can also temporarily switch to global mode from local mode by pressing the Option key (Mac) or Alt key (Windows).
Absolute and Delta positioning
Absolute positioning is when you measure the change in the position of an object in 3D with regard to the stage. Delta positioning is when you measure the change of position of an element in 3D from where it currently is. In the Properties panel, you can choose to use either Absolute or Delta positioning, or you can switch back and forth as needed to precisely position an element.
Selecting the absolute setting shows how the object is positioned relative to the stage:
Selecting the delta setting shows zero for all parameters between adjustments. When you enter another value, the object will move that amount, and once that amount has been entered, the values will return to zero:
