# Trim Slice Stack

## About this Block

The Trim Slice Stack Block trims a slice stack with an implicit body. The stack to remain can either be the inside, which are the slices that overlap with the body or the outside, which are the slices that do not overlap with the body. The feature tolerance is the minimum feature size of the trimmed boundary. This might result in open contours.

*This file trims a sliced cube stack with an implicit sphere to only keep the slices within the sphere.*

***

Trims a slice stack to exist only within the bounds of the body. Doing so may result in open contours.
