Exporting a model for space claim

[brianlynn]

I need to create a model to put on our web site to use for space claim in
other software (Revit).

I have tried using shrinkwrap, but I think that it was not built with my
situation in mind.

I have an assembly with a mix of different kinds of parts, sheet metal,
plastic, purchased parts that are cast and electronic components.

We are using WF 3.m050.

We use relative accuracy, out of the box.

I have tried several ways of making shrinkwrap work so I could just have
the outside shape of the assembly, and Pro/E unexpectedly exits during the
Merged Solid "refining analysis" stage of the creation. Faceted Solid
gives me something, but Marketing doesn't want that ugly thing on our
web-site. Surface Subset either fails to generate or gives too much
detail, and I am uncertain how well it will work in the other software.

I have tried to export to a couple of different file formats, but most
results have too much of the guts of the assembly.

I finally exported to IGES and then opened the IGES file in Pro/E. I was
able to remove a lot of the guts manually then without blowing up the
assembly, a few of the parts I had to replace with the origins because the
IGES ones were just a surface of the model that I couldn't do much with.

I tried shrinkwrap again with this newer stripped down assembly with
similar results.

Maybe I just don't understand shrink wrap well enough, does anyone have a
best practices document for shrinkwraps?

We don't use simplified reps so I do not know that much about those.
Should I be using some kind of simplified rep?

Thank you for taking the time to read this, if you have any ideas of how
to get this thing in a usable format with as little internal detail as
possible, please respond.

Would using copy geom get you just the surfaces you want?

Presently we use shrinkwraps for customers without many problems (except file size).

The method is as follows:

- create a solid part which fills the interior of the assembly (e.g. by using the inner sides of the sheetmetal housing) and assemble this as one of the first components

- hide or suppress any components You don't need

- save a copy as shrinkwrap with the following settings: merged solid, quality 3 (our parts are about 150 mm square), no automatic hole filling.

Sometimes it proves necessary to explicitly add some smaller components manually, but only because they have been missing in the result, not because the shrinkwrap fails.

This method has worked so far (Wildfire 2, M230)

Here is the summary of responses I received, including the original
e-mail. Thank you to Arnold, David & Martin. I still do not have a solid
solution, but I think I am a lot closer than I was.
