modeling thick walls

[RiffRap]

I think this is a skeinfox/forge question, but maybe a question about
Sketchup. Sketchup always makes "hollow" walls, because it only thinks
about edges and surfaces, right? So if I make an object with thick
walls, they are empty and then they print out like that. Is there an
option in Sketchup or one in Skeinfox to have the walls be filled in
so they are stronger/thicker/watertight? I tried messing a little with
the "Fill" settings, but didn't seem to have any effect.
thanks

Look for settings related to "number of shells". Don't remember where
exactly they're found; increase them to 2 or 3 shells.

yeah it's the extra shell settings like Andrew said. it's in the Fill
tab.

if you are changing a setting and it is not carrying over then make
sure you save in skeinforge (writes the file) and then click save
changes in the skeinfox window (commits the file to the version
tracking repo). are the setting changes you made showing up correctly
the next time you launch skeinforge (i.e. were they saved?)?

This isn't really true. It's a trick of the way sketchup draws it.

Basically, if you make an enclosed object shape that is "water
tight" (referring to it's flat surfaces have no gaps between them, not
that the resulting solid object would hold water) then the walls are
"solid."

Notice how in sketchup there are two different sides to each flat
face, and that one is drawn darker by default? The darker is an
"inside" side and the goal is to make all of those invisible when
"looking" at the object in sketchup.

I like to use the CADSpan plugin (http://www.cadspan.com) for it's
visualizer style. It makes the outsides darn tan and the insides red.
That way, if you see red (and aren't in x-ray mode) then something
needs fixed.

Does that make sense?

I use Solidworks and I'm getting hollow walls on thin objects too. I've messed around with shells and have had no luck. I've used 1 extra shell and solid infill. no luck. I'm going to try 0 shells and solid infill tonight and see what happens. It's probably one of those '% of wall thickness over base material overlap integer shell %' type settings that are indecipherable.

please post your stl models to thingiverse and provide screenshots of what you are talking about. maybe i'm misunderstanding.
