Portico created from arrays of columns
With gmax, you can quickly create multiple versions of one or more selected objects. You do this while you move, rotate, or scale the selection.
The general term for duplicating objects is cloning. This section presents all the methods and choices available for cloning objects. In addition to the transform method, the tools include the following:
Array lets you set all three transforms, in all three dimensions, at the same time. The results are precise linear and circular arrays in 2D or 3D space.
Mirror produces a "reflected" clone about one or more axes. If you mirror an object without cloning, the result is a "flip" to a new location.
Snapshot lets you create clones equally spaced over time or distance, based on an animation path.
Spacing Tool distributes objects based on the current selection along a path defined by a spline or pair of points.
Any of the cloning techniques can be animated. These topics supply overview information, as well as specifics of animation for each of them:
