Doubly Nested Contour 2

[felix7502]

I just tried to rebuild a sketch that had previously rebuilt. I received this message, "The sketch contains a doubly nested contour.". I've deleted the highlighted lines and redrawn them, but I can't get rid of the message. Does anyone have a suggestion?
Thanks.

Sylvia,

Can you upload a screen shot to engineering.com?

Had you previously created a feature from the sketch?

When trying to extrude, highlight the Selected Contours section and select the areas (not geometry) you want extruded.

If you redrew the double-nested contour, what was the point in deleting it?

Right--the problem is with the lines being drawn wrong, but with them being drawn at all. Each set of contours creates a nested area--ostensibly to be used to create an area designated for an extruded cut or boss or whatever. If you nest several of these within others, how does SW know which area you're trying to designate as being cut/extruded versus not?

To solve this when I do it, instead of deleting the contour, transform that contour into construction lines. Use a new sketch to convert the entities of those construction lines and a new cut/boss feature with the new sketch. Breaking this into two steps allows SW to understand what you're attempting to do.

CorBlimeyLimey - Thanks, I think that will fix it. My co-worker back engineered a pcb in SW and then went on vacation, so I was left with a small correction that then created the problem. Every line I move takes 65 secs to rebuild and I'm getting pretty frustrated. Thanks again. Sylvia

Theophilus - Thanks for the explanation. Now I understand what the message was trying to tell me. Sylvia

SWX a couple of versions ago (I don't remember when) added a nice ability to easily handle doubly nested contours. All you have to do is say Okay to the warning box and then pick the sections you want turned into the feature. See the attached PowerPoint file showing a quick example. this dramatically sped things up for me since I no longer had to break things into multiple sketches/features.

This is one of the items that is not well identified in SWX help, but it looks like "contour types for features" is the closest thing.
