Setting preference for which surface gets displayed when surfaces intersect

[MichaelkSA]

Using NX 9.

When I do boolean operations to add components like windows onto a body for visualisation purposes, there seems to be conflicts in which of the components actually gets displayed, which results in 'ugly' surfaces, as seen in the attached image.

Is there a way to set which component gets displayed when two surfaces are exactly overlaid? Something like the layers capability in a photo editing program.

I know NX uses layers, but I haven;t used it before and don't think it is the right workflow for this situation.

Thanks in advance.

Hi,
You can use COLOR FILTERING for enabling selections for some particular colors only while leaving the rest.

Hi Kapil,

Thank you very much.

Firstly, I am not really managing to understand how to implement the filters, it seems like even though I select different colours, they are taking no effect in the assembly.

Secondly, I am not sure it is the correct approach because I actually want both colours (in my attached image) to display, I just want the one to show above the other where they overlap, if that makes sense?

Since all shaded objects are in reality faceted models, what you're seeing is that since the facets are not identical on both sheets there is going to be interferences between them. What you should do is rather then creating separate sheet bodies is to create a single surface with subdivided regions, which as individual faces, can then be assigned whatever color that you wish. The Divide Face operation is like 'trimming' except that we don't throw away any parts of the surface. BTW, this also works when working on the face of a Solid body.

See the attached sheet body with a subdivided region.

That works perfectly.

Thank you very much.
