| Nonmanifold parts enclosed in manifold parts? [message #45905] Sat, 24 March 2012 09:16 UTC |

How does the printing software handle nonmanifold items, like details, that are enclosed in manifold objects?
here is an example of what i mean:
The cube is fully manifold, though the dome doesn't have a face on the bottom.

It will get rejected. Each shell needs to be manifold and watertight.
At least for this simple of a model, you are not "Required" to boolean the shells together, but it becomes a good idea as the complexity of the model increases

Interestingly, Shapeways accepts such a model and fixes is correctly, see http://shpws.me/4V9u - I don't know what might happen with a more complicated model of consisting of many closed and open shells though.
NetFabb Cloud service also accepts such a model. The service booleans the closed and open shells together quite nicely which gives scope for a more complicated model using the service to join parts in stages.
