region of faces-solid

[Nic65]

Good morning, everyone, how are you? I haven't written a bit, but I'm constantly following the forum. before I ask you my question I take the opportunity to thank you for all the tips you make available to the nx prophans as the undersigned.:finger:

Here's my problem. I have to cut a solid with a region of faces. Unfortunately, there are incongruent areas with the operation and I am obligated to have them going for attempts as the only message that appears warns only that double solids cannot be created. This involves a considerable loss of time.
I kindly ask if someone is aware of a command/system that allows nx to highlight the areas for him "difettose" during cutting a solid with a region of faces. The system I use is nx5.

Thank you in advance for your attention.

Hi:

 

[IPdesign]

try instead of cutting it to divide the solid
I think with the 5 you generate more solid deparameterized
at that point check which solids the system has created and directs you to conseguneza

But be careful not to save after deparameterization, otherwise the grape no longer works and you will not be able to return to the starting point

thanks for the answer ipdesign :finger:

I tried to follow your advice, but unfortunately I can't divide it. the problem I believe is that many edges of the surfaces coincide with the edges of the solid and, despite the setting of the tolerance is 0.025, nx also hears the openings/dissections between curves/sprays of 0.001 and beyond.

On three working days, I lost half of her looking for these, so let's say, modeling defects. when working with catia v4 I remember that if you could not divide a solid with a skin the system indicated with triangles the opening zones. This led to make targeted changes and avoid wasting time. I don't mean that v4 is better than nx, indeed. I was convinced that there was a similar solution.

hi, from what I know, there is no possibility of distinguishing 'defects' from errors: in the first of the images that place you, the error message that signals is reproduced. In this case it might be that the intent is wrong and not the model (I don't know if I was clear). in the second image there is the same operation made with nx 7.5: Here the situation is worse because the trim does the same to you and so, in case of microimperfections, you don't even notice.
p.s. can you post maybe a parasolid of a little bit that makes you mistake so I'll take a look?
Hi.

Hello baskets, thank you for the answer.

I also thank you for being offered to analyze the problem, but (finally) the model I have completed. Anyway, the problem is exactly what you're talking about. I attach images of the model. in image 1, 2 and 3 I indicated some of the areas where the model had problems. They are all edged areas. image 4 to show that it gave problems even in relatively simple areas, like just intersection between two floors. The problem is that all those surfaces have been extruded by the edge of the solid so I find it difficult to understand why it did not complete the cutting operation. in many areas I have obvious to the problem by entering with the surface in the solid of some tenth or offsetting the surface of 0.001 :biggrin:
Sure that if, as you say, the 7.5 completes the cutting operation by ignoring any errors (which then errors, in my case, are not) I can't wait to buy it:biggrin:
sin that there is no possibility in the command to select the margin of error to be ignored.

in my post I told you that the situation is worse and not better with nx 7.5, because you can find yourself with microsolids around that could give you trouble.
I didn't understand one thing anyway: error message can also appear in case the cutting surface has problems. for this you can use the geometry analysis (there are posts around) where you go to analyze how many boundaries the surface has (if it has an infimo hole e.g.).

no no, cutting surfaces have no problem. of this I am sure as they are surfaces from areas of faces obtained from solid. the problems encountered them at the intersection between the region of faces and the solid to be cut.
