# Chain
## Chain
The chain command allows us to select and copy a chain link using a curve, changing parameters such as rotations, copies, etc. This can be very useful for calculating the necessary links in a chain, even for chain rendering.
This command requires two elements: the link and the curve. For example, the link can be a single object or multiple objects, such as in cases where you want links with diamonds.
In the parameters, we'll define the number of copies and whether we wish to rotate the links. Note that we can rotate the even and odd links together or independently to achieve the desired effect.
The following image shows the difference between the **Include Ends** options**.** The first image shows the option enabled, while the second image shows it disabled.
