> ## Automatic Part Placement

> The Preview window includes two tools for automatically arranging parts. Use either one to automatically rearrange all of the parts in your print job.

> - Part Placement: This tool arranges parts for optimal build speed by moving the parts in the X and Y axes and rotating them around the Z axis, if needed. Since it does not rotate parts around the X or Y axes, the original upward-facing surface remains.
> - Quick Build Placement: (STL only) This tool will rotate parts in all axes to achieve the smallest possible Z height, as well as moving them in the X and Y planes. It may change from the original upward-facing surface.

> To use either tool, click its button on the tools toolbar or select its option from the Tools menu.

> NOTE: Quick Build Placement is not available for SLC files.
