Creating solid from surfaces
Creating solid from surfaces
(OP)
I know that if you 'sew' different surfaces together and if they form a water-tight body, the resulting 'sew' should be a solid.
The problem is, even though the surfaces I sew together seem to form a water-tight body the result I get is still a sheet body and not a solid, no matter how high I make the tolerance.
is there a function to test the water-tightness of a body?
I will really appreciate it if someone can give me a hand. The part file is attached.

Also, if you press Apply in the "sew" dialog, NX will highlight the open edges. ( Pressing OK does not.)

I did indeed increase the value of the distance tolerance. I even increased it to a ridiculous large value and it would still not stitch it to a solid.

I am on NX7.5, which is older than the part file was posted.

For starters, the base surfaces are not up to par - they "look" fine, but aren't G1 or G2 and 3 sided surfaces are used intermittently. Those issues may compound with the Patch Openings that are being used downstream. The base surfaces need to be extracted, untrimmed or Delete Edge used and recreated with a minimum of G1 where applicable. The cockpit area will get messy because the untrimmed edges won't line up.
Prime example where the underlying curve network was not up to par, therefore the resulting surfaces wouldn't Sew together. Take the time to clean up these areas and you'll end up with a nice fuselage.
Window and door openings need to have the edge curves extracted and can be projected onto the base fuselage to trim out. Same with areas where graphics are to be applied.

Cowski, I did indeed change the tolerances after creating the 'sew', so I will try to redo that process although from the comments after yours it seems like I still have some work to do on the geometry before that will work.
Tim, the stuff you propose is a bit advances for me as a new NX user but I will give it a try. Thanks.
A final question on the topic. After I have created a solid body. Is it possible to save that body as a single part file without all the part 'history' going along with it? Basically so that i can have a 'clean' part that i can pass along to other people without them needing to see exactly how I got the part to be as it is.

Notice if you create a solid block and use the fuselage faces to trim that block into a tube it works fine as long as the block starts aft of 130 and forward of 1020. Use this method to subtract a solid from the trouble spots and remove the parameters and see if deleting the faces of the block you subtracted from the sheets to heal the face.
Let us know how it goes.
