    Building a shell on a thin stl import

    AbnRanger- here is a Jing video- http://www.screencast.com/t/06vh6YTWf I was worried that small exterior holes might be messing things up so I cut off a small portion and capped it with a primitive. You can see, as Carlosa mentioned, if fills a few random bits but not the whole thing.

    Aarg! AbnRanger- I closed all the exterior holes and followed your directions but it would not work! I thought maybe I hadn't closed the form so I also did the process with a small section (capped with a primitive) and still no luck. Could the difference from yours be that it was not made in voxels, merely imported? Sigh! I have spent way too many hours on this... I think it might be time to give up.. gulp! Thanks for all your help everyone!

    Yes, it is big... But you should be able to download it from here: http://digimorph.org/specimens/Elephas_maximus/skull/

    Building a shell on a thin stl import

    carlosa- thanks but that didn't do the trick, my skull file, while solid has too many interior spaces and they would intersect. AbnRanger- thanks for the info on Jing! As you can see from my attached screenshot( a cross section for clarity) that I can do as you suggested but the problem is all the time it would take to mine out the interior forms. I tried doing this but it was very labor intensive and I often marred the structure I was trying to get. I only want to make the interior spaces positive- think filling a skull with a material and they removing all the bone. I only want the spaces that once held soft tissue (very halloween!) My idea was to add a greater thickness to the exterior thus giving more room to place my voxel object made from a primitive. This didn't seem to work because whenever I tried to add material to the exterior of the skull it distorted the interior spaces. Another idea was to make a solid voxel primitive that was exactly (or just slightly smaller) than my stl and doing the same "subtract from" with layers but I can't figure out a good way to make it exact. I am thinking that the orifices on the skull (nasal cavity, brain stem opening, etc) are making this even trickier? I could probably go into Rhino and close them if that would help. I don't know if then the "Fill voids" command would work?

    Building a shell on a thin stl import

    t complete image & cross-section Thanks but that didn't do anything. The file is an stl from a scan of a real skull. It is a closed form with many voids, many of which interconnect to exterior openings. I'd like to apply a thick shell that conformed to the exterior (exactly) as well as covered the orifices. Filling it exactly would work too because then I could subtract the stl from the solid form. any other thoughts?
  6. I am new and have chosen 3d coat to try and do a specific thing: I have imported an stl of a skull into voxels. What I would like to do is fill the interior spaces to study and extract them (ultimately with 3d printing). I have tried subtracting it from a cube but the is too much exterior material to try and remove without damaging the interior forms. Ideally I'd like to add to the surface thick enough to cover the cube. I have tried clay, extrude, etc in Voxels but it distorts the interior spaces of the skull. I have also tried extruding and building in Surface but I still get distortion and it has trouble revoxelizing. I am sure there is a simpler way to do this but I need some suggestions. Any ideas?

    Castinga void?

    I have not purchased yet so I am a super- newbie. I want to seeif this program can do a very specific operation... I have an stl file (a crocodile skull) from which I'd like to extract the negative space inside. Basically fill it up and then delete the original so I can see (and print) the shapes of the spaces. Someone suggested this could be done in Voxels. Can this be done without being too complicated?
