Is there a simple way to convert a surface model into a solid one? I asked a friend at work and he thought there was a trick involving shelling - any ideas or techniques would be appreciated.

Shelling is for solids. Turning surfaces into solids can be done two ways. You can 'Edit>Solidify' a completely enclosed, "watertight" volume just by picking the quilt (must also be completely merged) and solidifying it. Or you can thicken an open (like a shell or bowl) surface and doing 'Edit>Thicken'. Solidify is the most stringent in its demands on the type and quality of the surface; thicken can be done to almost any surface, providing all patches are merged. If you can't merge the patches to form a single quilt, Pro/e won't let you solidify/thicken it either.

Thanks for the info, didn't help in this case. The file is an imported iges with a single feature, and most options are greyed out
I don't know what the native format of the file was just want to get to something editable to allow extra cuts and protrusions, etc.
The top left is the file in Pro, top right is in Rhino to simplify creating sections/ tool paths.
If you open the IGES file in a text editor, wordpad or notepad, there should be some information in the header section about the originating system.
Looks like both pics are Rhino.
The bad news is; it's a facet rep model, either facet mesh objects (don't ~think~ you're going to work it in Pro/E unless you have REXX, ReStyle, etc.) or a planar surface representation of the mesh model (with a gazillion edges and faces satisfaction won't come easy if at all).
You'd probably be much better off working that in a system intended for mesh modeling.
If you set your selection filter to Geometry or Quilt are you able to select faces (anything?) in the graphics area?
What's listed in Rhino (mesh or planar faces)? If it's mesh objects you can mesh2nurbs (or something like that) to get planar faces, maybe join everything and export or vice-versa.

This is your nice, sweet, innocent, "just inquiring, mildly curious". SOLIDS!?! SHELLS!?! Then, somehow, out of that, we arrive at STLs and Rhino!?! WTF, you ignorant, lying, illiterate SOB (nicest thing I can say about someone who suckers me into a discussion and then tells me the discussion is about something entirely different). If ya got a practical question, like, I'm stuck, trying to get from here to here, we'd be glad to help!! If you got some theoretical "is it possible to....." yada yada yada, who cares and go grank yourself. I'm not answering those dumbass questions anymore, just to be made a fool of. Move on, we have better things to do.

Having trouble coming to grips with the "new" CAD forum model, David? All that's left out here is us hobbyists, school kids, drafters hired in over our abilities and, of course, the out-n-out shills. Or, maybe, it just goes with the new affordable, "easy to learn" Pro/E territory? You have my sympathy, but heck; they gotta learn it someplace. Loosen up, have some fun.
I asked because I don't know, if that makes me a dumbass so be it.
As for ignorant - don't tnink so I'm asking questions trying to learn. Lying????? Illiterate, probably and my mom dresses me funny too.
The question was asked because I know squat about surfaces in any cad program. I do appreciate all the HELP from the various posters, thanks for the info! I'll keep trying on my own.
With regards to being made a fool of ............
Well, I agree, you had the better, more "fun" answer (mesh2nurbs!?!?! how do you come up with this stuff, Jeff?) But, it took two posts to get this simple scenario out of him. He talks about shells, surfaces, iges and apparently knows nothing about faceted solds or STLs. I'm sure you'll be happy to know, we're not done with the fun yet, I'm absolutely certain of that. More dentistry to come. Always more teeth to pull. And, as far as teaching the newbies, I do it every day. They're a talkative bunch; they'll try very hard to describe the problem they're having, or, at least, just enough to get you up out of your chair so you'll come and take a look. And that's my problem (and always has been) with this forum, this pure text methodology: it depends totally on the ability of those who come here to communicate, in writing (no way we can be looking over their shoulders). And
9 out of 10 is horrible at written, verbal communication; and most of those, when you point this out to them, act as if it were a personal insult, really nerdy, social retard behavior. Engineers, no less, the ones whose professional lives are based on presumptions of objective, critical scrutiny, on data and numbers, which seem to hold sway until we examine their participation in this process of obtaining help. Then, I'm the bad guy for insisting that they not mumble, that they stand up straight, that they not stammer and instead, speak in complete English sentences and present a single, coherent, well formulated idea per paragraph. No wonder I scored in the 90th percentile on the CLEP test in English Compostion ~ the doofuses that come here brought the standard way down. Ah, well, that's kind of a come down.David Janes
I understand completely.
"Mesh2Nurbs" (had to look it up) is actually (Rhino command) MeshToNURB. Converts mesh object(s) to planar NURBS surf(s) which, I think, carry around more baggage as it's a more complex definition but at least normal solid or surface functions ~will~ work with it, albeit not very efficiently or effectively. That model (for RC's benefit) is a little over the top for a learning experience or for any "mechanical" or NURBS / Analytic surface based system, though. Maybe worth piddling with if the desires are dirt simple or you're just looking for an alternative to network TV? [Just speaking for myself; I'd rather follow Cliff's Winger bashing on comp.cad.solidworks. ]
