Hi eric, one quick note - one thing that really helps with figuring out what area is open is to set up a shortcut key with the following as the command part:

script: /* highlight naked edges */ var gd = moi.geometryDatabase; gd.deselectAll(); var breps = gd.getObjects().getBreps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getNakedEdges().setProperty( 'selected', true );


For example I have my N key set up with that script so that when I push N all naked edges in the model will be highlighted and you can see what areas are not fully closed.
