Can't do anything with facet feature 1

[treddie]

Howdie.
Have been attempting to export out a facet feature as anything that would work...Wavefront, IGES, STL,...but nothing works. All I get as output are files with nothing in them.
What I did was this. I had this Wavefront file (created from a ProE file) that is to be imported into a renderer. I reimported it into ProE to clean up the facets. Once I did that, I had a nice clean file, but can't export out to anything.
Looks great, but not much use sitting up there on the screen with nowhere to go.
I guess I could try cleaning it up in Rhino, but was just trying to figure out what is wrong with ProE (or me!).
Thanks,
treddie

Is it a tesselated / facet object or NURBS / Analytic surface representation? How did you modify the objects? REXX or ReStyle?

If it's a Facet Feature an STL export should(?) work. I just did one a couple of weeks ago (to Rhino for conversion to NURBS planar surfs so I could get section curves from it).

Hello Jeff.
Nice to hear from you.

This was originally the Famous Old Helmet From Hell, as you might recall. I had made some mods to the shape and the ProE model is sweet. Have been exporting out just the pure ellipsoid to do render checks for refraction issues. But when exporting out to Wavefront .obj the conversion left some ripples at the poles of the ellipsoid. It's not an issue with the ProE model as far as I can tell; curvature analysis indicates everything is very smooth with no discontinuities. So I imported the Wavelength .obj file back into ProE, did Right-Click > Edit definition and then did Facets > Clean > Mechanical to do an automatic clean-up. This very definitely flattened out the "rough" edges. But when attempting to export out again, I come up with empty files.

I forgot to mention that I actually did try STL, but it looked like it was interpreted by the renderer as two infinitely thin bubbles, one inside the other, instead of one bubble, with a thick surface. Weird. So this morning, I thought maybe recalc'g the normals in my renderer would fix it, and it did. So STL DOES work.

As for the other export options:
Exporting out as STEP crashes ProE to the desktop.
Zero files for all other applicable formats.

So...did a test render, and even after cleaning up the model via ProE, still ripples, but less pronounced where they were originally, new ripples elsewhere.

I think I'll live with the ripples. They're not THAT bad and they ARE only at the poles of the ellipsoid. At least I know that it's not a problem with the solid model in ProE, so I feel confident completing the revised model. I'll deal with the export problems in the
far and distant future when PTC fixs their export filters, we all live in air-conditioned domed cities of zero pollution and everyone (including all the animals) live in perfect peace.

;^) Sounds like a Eisenhower industrial military entertainment complex vision from the '50's.

Glad you got it working.

LOL!
I like that...Industrial Military Entertainment Complex. Eisenhower no less. 50s definitely.

Where is military entertainment when you need it?
