Eagle for 3D Laser Embedded Crystal - Polyloop

When the manufacturer images this file the interior shapes are imaged as well. Much like an Xray. I tried removing via boolean commands but the resulting objects are even more confusing.

Any suggestions?

You have to make your model "Water tight" to help with these kind of things. I've done 3d printing before and there seems to be a single difference to what you're doing, it is just tracing the hull of the object described by the mesh polygons(visible to us or not). Export your bird as an .obj and then use Amapi or Hexagon to perform boolean unions for each part. They must intersect at some point to form a manifold volume. I've attached a screenshot of your wing/torso boolean unioned in Hex and Amapi. One problem I saw was your head mesh is open around the neck feathers and does not intersect the torso mesh. Close the neck of the head then union it to the torso.
To speed it up I would ungroup all your wing feathers and get them all as a single vertex object. Also make your feet as separate meshes from the torso or model them from the torso to get rid of all the polys stuffed inside the bird. What the goal is to have just the hull without any polys inside the bird.
You avoid all of this if you model it all from a single mesh.

Can I hire you to make this a "watertight" model? I don't have the time or the extra software applications to pull this off.

Thank you for looking and posting a response.

Joe, give this a try.

Perfect!

Thank you so much!
Who is "Grendal"? Are you married with 3 children? If so, no wonder 30 days on a rig can get old!

I am married to the best woman in the world with two beautiful daughters. I work as an engineer for a oil drilling company responsible for the well architecture on the seafloor. Currently I am in 100 miles off the coast of Nigeria. Started 3d two years ago with a free version of Realsoft3D from Computer Arts magazine with a dune buggy tutorial. I am glad it worked out for you.
