How do the FBM assign the color attribute to the recognized features?

Genius

Hello Folks

 

Assuming I have two similar holes to be recognized by FBM as shown below.

 

 

The first hole is assigned with blue(color code=212).

The second hole is assigned with orange(color code=114).

 

How did this happen? It looks like FBM pick different face's color, first hole pick the blue of hole cylinder, second pick the orange of countersink face.

How to change this behavior of FBM?

 

Thanks

Sean

Color in general is not reliable at all, so a better way would be to use face attributes, which are much harder to change by a user, since the color can be changed within a second easily.

What would the colors indicate?

Are there also face attributes holding the same information?

Hello Stefan

 

Thanks for your quick reply, user felt it is too annoying to add face attribute one by one.

 

The color indicates different features.

There are no  face attributes holding the same information

I just found the reason. User have to convert to parasolid then import it back to NX

Is the color applied manually or is it part of the subtracted body?

Do you use Mold Wizard? If yes, then you already have MW_HOLE_... face attributes available, if the standard part is set up correctly. You only need to add them to the STEP class in MKE to use them with your machining rules.

The COLOR attribute is a single value.
If the faces of the feature have multiple colors then the COLOR attribute gets one of these at random. To indicate the value is a random, the minus sign is added.

Thanks, that makes sense.

 

Could Siemens make an enhancement to recognize and pick face color of certain part of a feature?

You can always file an ER.

However generally we do not encourage the use of color to annotate models and often there are better - more persistent - alternatives.

It would be interesting to know what you are trying to achieve.

I strongly support  @SeanHAI  file an ER. I think it's a good way to seperate different machine method. and easy to use . and for complex part of mold, We use color to indicate which should machine and ensure the precision and other part can roughly machine it. you can't assign attribute to thousands of faces. it's not work.

Hi Matin,

Your part got my attention.

How many of your part features can be programmed with FBM?
