some faces in my part are transparent, can this be fixed?

some faces in my part are transparent, can this be fixed?

some faces in my part are transparent, can this be fixed?

(OP)
I've converted a file from probably catia, successfully.  It actually came in as a solid part file, but a few faces on the part are transparent, and stay transparent while the rest is solid looking.  I've sectioned the part view with no problem, and made a drawing out of it, with a successful section view, with hatch lines and everything, but the transparent faces wont behave.  I've saved it as parasolid, and converted with no change.  I've made a block around it, subtracted the part body from the block body(making a cavity mold if you will), then made a second block body around that and subtracted the cavitized block body from the new fresh block body, and end up with the exact same original looking part with transparent faces still there.  Any ideas will be helpful (short of the VAR's standard answer "have you updated your video drivers lately".

What version of SW?  Have you tried to remove the face's appearance callout?

#1)  I running 2008 sp 4.
#2)  I think I have, but I'm going to detail that process so you can tell me if I really have or not.  with the part file open, I click on the part name at the top of the design tree, the click the edit colors button.  the color and optics box comes up and under selection 3 of the four buttons are not greyed out, the select surfaces, select faces, and select bodies.  the select features button is greyed out.  In the selection box it says Imported1, and below that I click the remove all colors button.  Then I click the checkmark and go back to the same model, then I hit the ctrl q with still no change.  Is that the correct process?  If so then the answer to your question is yes.   

RE: some faces in my part are transparent, can this be fixed?

Sounds like some of your faces are facing the wrong direction.  I've seen this with imported stuff before.  Try turning on "Verification On Rebuild".

Is it possible to post your file?

Also, try Insert->Surface->Offset.  See which direction it offsets on your transparent faces.  If the new, offset surface is inside your model then the faces are definitely facing in the wrong direction.

Someyimes invisible faces are a sign of corruption during import or export.

RMB the import feature and do "Import Diagnosis", the repair faces.

Well I've tried 3 times to upload it, but apparently it's to big or our security geeks are working ot.  I tried the verification on rebuild, but dont really know what I should be looking for with it turned on.  And I tried to offset the surface, and it wont do it any direction at any distance.
 

RE: some faces in my part are transparent, can this be fixed?

(OP)
The Diagnosis turned up 11 faulty faces, and I repaired all but 2.  but still have the issue.  Keep the ideas coming.   

RE: some faces in my part are transparent, can this be fixed?

Try zipping the file for uploading. Are you uploading via the ENGINEERING.com link below?

What format is the file?  IGES? STEP?  If you open the file in Notepad you should see the originating program in the header.

As indicated, right click on the file name in Windows Explorer and select Send to Compressed (zipped) Folder and then try attaching the resulting *.zip file here.  If still too large there are several file hosting sites where you could post the file and supply the url here.
