SO long story short, there's a random glitch that occurs when I subctract two solids from each other...
And then, THIS DONUT appears!
Has anyone else had something similar? We can not get rid of it.
If anyone has experienced similar, we'd like to hear.
Solved! Go to Solution.
So you are subtracting solid B from solid A
I'm suspecting solid B has a "hole" in it.
If you do a "modeling" section of solid B (before the subtract), is the cross section "solid" or is there a "hole"?
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
Hope this helps visualize...
The green part is B
Cross sectioned, it is solid.
This yellow block is A
When Cross sectioned, it is also solid.
Now, Subtracting B from A looks like...
Final product is this... with a floating donut shape... where does this come from?!
I'm guessing that one of the blends is ignoring its trim boundaries after the subtract command.
I've seen something similar when a blend face ran amok. I ran the "examine geometry" command and found that one of the bodies had some geometry errors that needed to be fixed. After the corrections, the part behaved in the expected manner.
Were both of these parts created from scratch in NX? If they weren't you could try using the Optimize Face command to clean up the geometry and as @cowski1 suggests, use Examine Geometry to locate any potential issues. I've seen similar issues that were sent to the Parasolid development team to review, so if you're not able to resolve the condition please consider opening a new IR with GTAC.
You tagged this NX10, but are you using the latest version; NX10.0.3? Do you have NX11 available to test the same boolean? I'd be curious to know if it's something that occurs in newer versions.
We use both NX8 and 10 at the moment. We have an available upgrade to 11... In this long process of transitioning over.
Our license server currently does not have 11 available.
I will try Optimize Face and Examine Geometry.
