We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

      nOn the Facets tab, use the Separate All button to make a separate facet body for each interior cavity.nSeparate the facet bodies using Components (may be an optional step?).nShrinkwrap each facet body one at a time.nOn the Design tab, use the Combine tool to subtract the interior solids from the exterior solid to recreate the cavities.n

      the seperate all function didn't work when I selected the whole geometry. Once I cut out the bounding faces and then used it, it created individual facets. Not all of them could be shrinkwrapped(those ones I deleted). I converted the remaining shrink-wrapped bodies into solids and tried to subtract it from a cube of dimensions same as the bounding box but it showed errors. n

      the pores don't have any bounding surface. is that the region it wont let me subtract it from a solid? I am very confused regarding how to get this geometry resolved.nn

      nYou can create solid geometry then convert that to a Facet Body.nYou can use a Facet Surface to cut a Facet Body.nYou have to learn all the tools on the Facet tab,nTry to do one pore at a time.nIt is a tedious process.nn
