Understanding how to nest parts relies on recognizing that height sets the vertical space a part will occupy in the build volume. When parts have different heights, the tallest part determines the maximum build height you can use in a single nest, and shorter parts must be placed with enough vertical clearance so layers don’t collide as the build progresses. In practice, you measure each part’s height and plan placement so the overall height stays within the printer’s limits and any necessary supports won’t interfere across parts. If height isn’t considered, you risk overlaps between parts, misaligned layers, or unstable builds. The other factors don’t affect vertical arrangement: color coding helps organization, scheduling concerns timing, and material finish relates to post-processing.
