drawing view update fail nx9

[carliro]

Hi Guys,

Lately in several models I have such an error while updating view in drafting... What I did I've replaced component which is similar under drafing cad file and then wanted to update the views as long I need the same views ... but for just some of them update fails.

Anyone knows how to fix that? I see what that errors says just it is impossible to change anything in the model, it looks it is fine.


View Update Report
------------------

View name: SX@28
View type: Section view
Error: Unable to subtract solids for sectioning.

A solid could not be sectioned.
Part "108T5522G0001.prt" may have some invalid
geometry along the cut plane that is causing
operation the sectioning to fail.

what happens when the view fails to update ?
do you get a message ?

Make 108T5522G0001.prt your displayed part and run Analysis -> Examine Geometry on the solid to verify that there isn't anything wrong with the topology of the model. Sometimes how it looks isn't enough. Also, confirm that the solid belongs to all the correct reference sets.

You can verify if the error message is giving you the true cause. Switch to the model and run the "examine geometry" command: Menu -> analysis -> examine geometry, body checks: turn on all the options, face checks: turn on self-intersection and spikes/cuts (smoothness is optional). Window select around your model and press "examine geometry". If it fails any of the checks, that is probably the cause of your problem.

Other things to try:
[ul]
[li]Make sure all the section lines are associated to the model (none are in the 'retained' state).[/li]
[li]Make sure the cut lines are in sensible locations (none are tangent to a hole in the model, for instance)[/li]
[li]Try moving the cut plane a small distance from its current position[/li]
[/ul]

Jerry,

this is the message I receive.

 

[jerry1423]

I have a feeling that you need to re-associate your section (cutting plane) lines to the new part.
I am not certain how to do it in NX9, but basically you need to re-pick the points in the drawing view that are linked to the part and section lines.

Jerry I have added new section view exactly the same as one I need and the same situation so that may not be the re-picking the points? I am trying the examin geometry.

Cowski in the past yes it worked on different model that I move section plane a little bit from center point.

This is the report, I dont know what I can fix as I am working on assembly drawing and all components are released (no modify posibility)

Yep, bad geometry.

It might take a revision, but any part can be modified. If it has been released recently and is not yet in production, the "approvers" may be able to roll it back for modification.

It is my opinion that an "examine geometry" check should be part of the release process.

[carliro]

But, why I can have it shown with intersections shown on my view?

 

[carliro]

why it works (section updates) when I cut model not exactly through the center?

 

[Toost]

The things in your examine geometry test to bother about are the:

Consistency

Self-intersecting geometry detected
Please replace incorrect geometry

Face Self-intersection

Self-intersecting face detected
Please replace incorrect face

The other objects in that report should not affect the section view.

When you have executed the test, there are tickboxes you can toggle to highlight the erratic faces.
Correct these, and revise the parts.

Regards,
Tomas

as an comaprison, it this model also bad geometry?

[carliro]

Ok Toost, so it means that smoothness and tolerances at edge checks/post check status are possible.

 

[carliro]

You guys say that inteference is making troubles.
What if I want to show interference in the section view?
What to do if I have a bolt and threaded hole where interference is not possible to omitt because it is always showing engagement?

Is it really intereference issue?

 

[carliro]

Guys,

I have suppressed some operations that were making consistency error and the view has updated ... I need to figure out how to model similar geometry just with no cosistensy issue

 

[jerry1423]

to show interferences go into
View style -> hidden line tab -> check yes, with interference curves
