How to Align Objects in Maya
It is handy to be able to align multiple objects in the scene. By selecting multiple objects and using the Align Objects menu item the process is quite simple.
Add three polygon spheres with different diameters to the workspace (Create > Polygon Primitives > Sphere). Move the objects to random, non aligned locations.
Select all three spheres by shift or marquee selecting.
Choose Modify > Snap Align Objects > Align Objects and include the options.
Click the Min, Mid or Max icon and choose one or multiple axes to perform the operation.
Click the Align or Apply button to accept the settings.
