People,

am guessing this is going to be 'simple'
using NX7.5 ... can someone share the process from taking a complex shell and making it a solid ...

many thanks .... just the commands I should be looking for would be a good start

regards ... gary

Look into synchronous modeling, copy face feature. Then use mesh surface to close it, and sew it all together?

Best regards,

There's no quick, one-hit button for this, as it depends on the geometry and circumstances. In general, you need to use Analysis > Examine Geometry to determine any openings in the body, fill those surfaces manually, then sew it all together.

thanks for the heads up.
I now have what I consider to be a 'sewn-up' volume, would I have expected it to have become
a solid body on completion or is there a further discrete command that says make this volume a solid

regards
 
There are at least 2 things that may prevent a sewing operation to produce a solid body:
[ol 1]
[li]there may be gaps between edges that are not easily visible but are larger than the modeling/sew tolerance[/li]
[li]the original sew operation had gaps/holes which you later filled in and added by editing the existing sew operation[/li]
[/ol]

In the case of (1), you can use the 'examine geometry' command to help find 'sheet boundaries'.
In the case of (2), a sew operation that creates a sheet body cannot be later edited to create a solid body. If the original sew had gaps/holes, simply create another sew feature to add the necessary sheets and it will create a solid.

You can do any of the following:

1. Hover your mouse over the body until you see 3 dots next to your cursor (...) then select the body and there should be a small box pop up called Quick Pick with a listing of features and geometry. See if Solid Body is in there somewhere. If it is, you've successfully sewn the sheets into a solid. If not, then you need to delete the Sew feature, find where the gap is at, repair it and recreate the Sew. See #3 for some tips on checking for a successful Sew into a solid.

2. Set your Preselection Type to Solid and hover your mouse over the body - if it highlights, you have a solid.

3. Delete your Sew feature and pay close attention to your Cue/Status line as well as the graphical feedback as you recreate the Sew. Any unjoined edges will highlight in red after you press OK/Apply. The Cue/Status line will flash something to the effect of "Solid Body created" very quickly.
