> Making a segment that has fractured, discontinuous boundary and holes inside to be a simple solid object is a quite common task for segmentation. For example it is needed for creating simple solid bone models from CT images, extracting skin surface, segment thin surfaces, such as orbital bone wall, measuring brain volume, or volumes of various cavities. Slicer now has a tool for all this: “Wrap Solidify” Segment Editor effect, provided by [SurfaceWrapSolidify extension](https://github.com/sebastianandress/Slicer-SurfaceWrapSolidify) and contributed by Sebasti…
