There are three ways to copy an object.
Copy Using the Context Menu
Select the object by double-clicking it.
Right-click the object.
Select the Copy tool in the Context Menu.
Right-click anywhere else in the scene and choose the Paste button.
Note: This also works with CTRL + C or V. Use Paste In Place (CTRL+Shift+V) to paste an object exactly where it was copied from.
Copy Using the CTRL Key
Select the object by clicking it (double-click to select a whole body or everything attached).
Press and hold the CTRL key and start dragging the object, or start moving the object and then tap CTRL
Instead of moving the object, you'll now be moving a copy of it.
Note that Ctrl-copy does not currently work when Touch Mode is enabled.
In Touch Mode, you'll need to use the copy/paste tools in the Context Menu (press and hold) or use Ctrl+C and Ctrl+V, then place the object down, and reposition it as needed.
Copy Using the Array Tool
Select the object by double-clicking it
Right-click the object and select the Array tool
Select the number of copies you want to make
Choose whether the next drag will define the distance between two objects or the total length of the array.
Click OK .
