Description of the different steps

1. Use the Translate tool:
   1. Select your part, go to the Tools ribbon, and then click Translate.
   2. Either enter the resulting coordinates, or the relative translation value; and click on Apply.
   3. As an alternative, use the interactive translation tools. The red, green and blue arrows move your part along the X, Y, and Z axes, respectively.
   4. Use the To default position and To default Z buttons to quickly place a part on these locations.
2. Use the Automatic Placement tool:
   1. Part interval: The distance between your parts
   2. Platform margin: Te distance between the edge of your platform, and the parts.
   3. Make a choice to Nest all parts, or only the Selected parts.
   4. Make a choice to translate all parts to the default Z-height, or keep the current Z-height.
   5. If you have too many parts to fit into a platform, you can enable multi-platform placement.
   6. Bounding box: Takes the bounding boxes of a part into account.
   7. Geometry: Considers the original shape of a part.
   8. Placement solution: Make a choice to stop at the first solution, or when the minimal surface area, X-dimension or Y-dimension is reached. You can also place the part in the platform center.
   9. Part placement: Set the automatic placement tool to only translate, or translate and rotate your parts with degree intervals you specify.
