How to Copy in 3ds Max?

The quickest way to copy objects in 3ds Max is by using the Shift key while performing a transform operation (Move, Rotate, or Scale). This process is generally known as cloning.

Cloning Objects in 3ds Max

With 3ds Max, you can rapidly create multiple versions of one or more selected objects during a transform operation. Instead of using a specific "copy" command from a menu, you incorporate cloning directly into your workflow as you position, orient, or size objects in your scene.

This method allows you to create copies, instances, or references in a single action, offering flexibility depending on your needs.

Step-by-Step Cloning Process

Here's how to duplicate an object using the Shift key:

1. Select the object(s) you want to copy.
2. Activate a Transform tool from the main toolbar (Move, Rotate, or Scale).
3. Click and hold down the mouse button on the selected object(s) or their gizmo.
4. While still holding the mouse button, hold down the Shift key on your keyboard.
5. Perform the transform operation (move the mouse to move the copy, rotate to rotate it, or scale to scale it).
6. Release the mouse button.
7. The Clone Options dialog box will appear.
8. In the dialog box, select the Object Type you want:
   • Copy: Creates a completely independent duplicate.
   • Instance: Creates a duplicate linked to the original, where modifications to one affect the other (though some properties can be independent).
   • Reference: Creates a duplicate where some properties (like mesh data) are linked to the original, but modifiers applied to the reference clone are unique.
9. Specify the Number of Copies you want to create.
10. Click OK to create the clone(s).

By holding down the Shift key during a move, rotate, or scale action, 3ds Max understands that you intend to duplicate the selected object(s) at the new position, rotation, or scale.

Understanding Clone Types

The Clone Options dialog gives you three distinct choices: Copy, Instance, and Reference. While the basic cloning method (Shift + Transform) is the same for all, the resulting duplicates behave differently.

• Copy: Best for creating independent duplicates that you plan to modify separately.
• Instance: Ideal for elements you need to duplicate many times (like chairs, trees, etc.) where you might want to make global changes later.
• Reference: Useful when you want variations of an object based on the original's base mesh but with unique modifiers.

Using the Shift key during a transform is the fundamental method for creating any of these types of duplicates in 3ds Max.
