Sewing Sheets to Solid body

[mike734]

I've seen this discussed here many times but I'm not having any success sewing together a ton of sheets that are from an imported iges file of a vendor's component. I got the sheets to succesfully sew together using a tolerance of .05 but I still have a sewn sheet. When I look at the section view in modeling and in drafting it is not a solid section it's a section through a hollow sheet body.

Any tips or advice would be much appreciated. I've uploaded the .prt fileI'm using NX7.5 by the way.

Thank you very much,
Mike

If you look closely at your model you have a gap between the sheets. I'm including a picture.

Though I admit the sew function is tricky and finicky, you cannot have any gaps between your sheets for the sew to create a solid.

You're referring to the thin silver sliver/line in between all the red? I'll give it a shot to sew those 2 together.

The smaller surface just needs to be untrimmed using Edit -> Surface -> Boundary. Once it's untrimmed, it will Sew using a much tighter tolerance than 0.05.

This model has many things that need to be done to it before it will Sew into a solid. The bottom pale green surfaces are overlapping the maroon surfaces - they need to share common edges or be trimmed to each other.

Is this a bottle or container? If so, the inner surface is missing and as a result will never Sew into a solid. All surfaces must enclose a volume.

Thank you very much for the help. I'll try and mend that one sliver where there is a gap.

No, this is a handle. Do I need to have the surfaces dual-sided. I figured a surface already has inner and outer surfaces to it.

Thank you.

Not only do you have gaps, you also have self-intersecting faces. To find these, change NX to Modeling and then run...

Analysis -> Examine Geometry...

...and select the 'Set All' button and then select all object on the screen. In addition to some 'Tiny' and 'Misaligned' objects, but the big problems are the 'Face Intersections' and the 'Sheet Boundaries'.

Here is a picture of a cross section of your model showing where these Face Intersections and gaps are located:

Hi mike734 ,
I am attaching a parasolid of the solid (since i am NX8.0 so thought it would be good you can have it in other format.).
Besides this i will be attaching a ppt (i have worked a lot on such stuff in the past and here are some thumbrules).
