Making sheets a solid body

[MichEng211]

According to this thread:

http://www.eng-tips.com/viewthread.cfm?qid=287332&page=6

Making a sew of watertight sheets produces a solid. How can I verify that my object is, in fact, a solid?

Also, why is it that when I sew a body together it sews, but when I use the sheets to solids assistant, it is unable to sew with the same tolerance? I can't get the sheets to solids assitant to make my body a solid by any means.

Also, by my understanding, a sheet boundary is a crack in the model between sheets. Is this correct? How can I mitigate/remove them? So far I have been importing my IGS exports to ANSA, fixing the geometry issues, and exporting them back to NX. Is there a better way to fix boundaries in NX?

I am using NX7, by the way.
Thanks for any help!

When you're using the Sew function, after the operation is complete and if a solid was created, in the status line it will state the a solid was created. If you miss the bit of information, you can always just select the model and see if the status line states that a solid has been selected. Of course you could also use the Information -> Object... function and it will will tell you what it is.

Now if it turns out that the model is still a sheet body due to 'cracks' you could open up (set to a larger value) the tolerance used in the Sew command. Or you could try going to...

File -> Export -> Heal Geometry...

...and see if that fixes the cracks (you may have to perform the sewing operation again).

You can also check the mass properties to see if it's a solid. Analysis - Measure Bodies. If you can't select the model then it's not a solid.

Excellent. I can select it and it shows up as a solid.
I really appreciate both of your guys' help.
