convert a plain surface type to a plain surface 2

[uwam2ie]

I'm fighting with convert to sheetmetal in nx 8.5. After hours of analysing I found out, that at the imported models some plain faces at flanges are b-surface types what will later after thickening fail on convert to sheetmetall. Can I convert them to planar faces or do I have to receate them?
thx in advance

What version of NX?
NX8 has the synchronous command "optimize face" which might help.

Note that with NX 8.5 there are a new Sheet Metal option when it comes to converting an existing solid into a Sheet Metal model. I would try the new 'Convert to Sheet Metal Wizard' first. It's similar to the older 'Convert to Sheet Metal' function except that we've now includes the option to perform a 'clean-up' as part of the conversion workflow and if it still has problems it actually recommends that perhaps using the Optimize tools mentioned by cowski might be a good place to start this process.

... all you tipps, thanks, don't work
I've attched theexample

ThThe best that I could do and still get a model that looked decent was getting it down to only 14 b-surfaces (there were 78 to start with) which means it still can't be converted 100% to a Sheet Metal part. What was the original system that the model was created on?

catia v5 when it helps

In nx2 or nx3 I remember there was a recreate face command- where is it gone?
THX in advance

I have also looked at this model and try to fixed it. Well, Wizard has showed, where the problematic areas are. I have subtracted those areas, then used the wizard and recreate three missing flanges.
I have attached the ppt, that may better explain, what I have been doing. Hope, that this helps somehow.

 

[uwam2ie]

thank you SvenBom,
yes, I did as you discribed - I have a lot of models to fix.
The thing is, the flanges doesn't look complex there are some complex faces look plain - doesn't work in conversion...
thx

 

[SvenBom]

Glad that I could help.
And about the flanges. I guess that it is not the problem with the main section of the flange. I guess, that it is the problem with the bend (transition from the main body to the flange). If you check closely, you will see, that the surfaces there are quite complex. And after the translation, those surfaces are not just simple blends anymore and therefore they can not be converted to the sheet metal.

The multi-armed "sheet metal monster" is starting to rear its ugly head. Thanks for the new "convert to sheetmetal" tool Siemens......please keep working on it.

[green]To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?[/green]

I posted some code a while back that would color B-surface faces of a selected body to yellow. It won't solve your problem, but it will help quickly identify the potentially problematic faces.
