I’m doing a sculpt that will be printed out and therefore want to make it hollow. I’m using the Create Shell function which s great. However, is there. Way to know What the number means when setting the thickness? I want to be abe to know what thickness I’m setting it to, knowing what sze the modell will be when printed. Is it a percentage or based on some weird ratio? Or what.
Anyone? Especially someone from Pixologic?
Is there really no one that will answer this? Someone from Pixologic perhaps, or someone with experience of using it?
I’m surprised you haven’t gotten an answer to this yet. The one time I have a posted question, I got a quick response.
It may be because the thickness is relative to your output. You haven’t told the zplugin “3D Print Exporter” what size the object is yet.
What I would like to know is…is there a non-destructive method for creating a hollow mesh with a hole? Even if you still wont be sure of how thick it is 
Dynamesh’s “Create Shell” is awesome in that this internal shell is not just extruded faces that can overlap, but is an averaged result, that produces no overlapping faces and requires little to no clean up. Bravo.
But, its remapping of polygon placement is destructive in that it can change the shape.
I know that higher value create tighter geometry which is less destructive, but my iMac w/16gb ram cant handle a value higher than 1300 in the Dynamesh resolution slider. And that is not enough mesh density to reduce its destructiveness to acceptable workable levels on models with tight corners.
Is there a way to create a hole, and hollow out geometry, that is currently arranged as GroupsLoops, in a non-destructive manner?
Groupsloops allows me to get the density where I need it, which translates well when Decimating, as Decimation respects that density. Dynamesh does not.
Creating a duplicate object, using negative Inflate, is just like a negative extrude and introduces overlapping geometry that need further cleanup.
Unless I am missing something, we could really benefit from an “Extrude to Shell” tool, that calculated a result similar to Dynamesh’s “Create Shell”, but was non-destructive. (of the exterior geometry, I dont much care if the internal geometry was changed as it wont be seen)
And, maybe, when you enter a numerical value for “Create Shell”, or “Extrude to Shell”, you would enter a “Intended size” value for the overall sculpt, therefore, the thickness slider would adjust itself to correspond the that measurement system/range. Hence, you will have certainty that the mesh you plan to export at 7 inches tall, now has a 1mm thick shell wall.
