Knitting Issues

Question asked by Raj Deshpande on Feb 9, 2009
Latest reply on Feb 13, 2009 by Jeff Mowry
I imported a legacy part ("Top Housing Before") that I would like to modify (see highlighted "blue" surfaces). Using Import Diagnostics I deleted faces and then tried to recreate new faces by patching the 3D sketches and remaining surfaces ("Top Housing After"). I was able to knit most of the surfaces except the two surfaces highlighted in "red". I tried several methods (tried to split and patch smaller areas) without success. I can see small gaps between the surfaces but I was unable to heal the gaps.

I have had few other issues with surfacing.
1. Once I started adding the features to imported part, I was unable to go back to Import Diagnostics (the option was suppressed) and modify imported surface. I had to delete all the features/changes (suppressing the features or rolling back did not work) before I could go back and modify the imported surface again. It would have saved some time if I could use Import Diagnostic tool interactively.
2. Once I stated knitting the surfaces, other near by surfaces started shifting. Please see screen shots before and after knitting. Is it something typical?
3. How does on pinpoint area or highlight surfaces that are causing problems? (e.g. in Import Diagnostics the invalid faces and gaps are highlighted). I tried using Tools/System Option/Performance/verification on rebuild without success.
4. Is there a simpler or different method one can use to modify imported parts/surfaces?
5. How do I minimize the file size? The file size increased in excess of 60+ Meg in one case.

I would appreciate any help you can provide. Thank you.
