Use of the kill-blend command

[lbw]

Why did kill-blend not take effect, I used the model 0046_boxblend_01_coloured.stp from the example, did a simple test, selected a blend and executed kill-blend, but the model didn't change

It requires face ID as the argument. In that case, it would be

> kill-blend 3

Generally, you may want to try kill-blends-inc to check what this command can and cannot do.

kill-blend 3 also does not work, in fact, I selected the face with id 3 by mouse, execute kill-blend, and directly through the kill-blend 3 specified face id 3 effect should be the same, can not work successfully is it my compilation time problem?

 

[Quaoar]

That's weird. This is how it works for me, and I was pretty confident in this functionality as it has been protected with automatic tests from day one. Do you build Analysis Situs yourself? Can you try it in the latest release after installation?

 

[lbw]

My release version is not fully functional, there are some problems, I debugged the program in debug mode, I found the approximate error of kill-blend, it appeared in the place of recognising the blend,
so I used the recognize-blends command, and sure enough, it can't recognise the blends, here's the configuration of my compilation, do you see any problem with it?

 

[Quaoar]

Do you mean that the recognize-blends Tcl command does not select any faces when you run it interactively? There does not seem to be anything wrong with your cmake configuration, but what I asked is whether this version works for you or not. You may want to dig a bit deeper into the recognition code of blends to see where it actually exits. I can help you with understanding the code.

 

[lbw]

Yes, I'm using the recognize-blends Tcl command .I got inside the recogniser.Perform function.

this is some debugging results, I'm not sure what they mean.



I went into the recognizer.Perform function inside, see the last obtained result id is empty

into the GetFaceIndices function found that m_data is empty,

it should be featureRes caused,

I went into the extractor.Perform(m_aag, featureRes, filter) function, found that all the face into the if ( !aag->HasNodeAttributes(fid) ) judgement, and then execute continue; can not enter the next TColStd_PackedMapOfInteger &
feature = result->FindFeature( type, attr->GetFeatureId() ); function, so there is no data for m_data，but I don't understand what is the direct cause of this problem

Can you try putting a conditional breakpoint here for face 3 and trace forward where it returns false?

 

[lbw]

I set a conditional breakpoint here for face 3, but when face is 1, it executes if ( asiAlgo_Utils::IsPlanar(face) )
and return false; a conditional breakpoint here for face 3 is not executed.

 

[Quaoar]

That's correct, face 1 is planar, and this code is looking for a curved fillet face (it should be face 3). Here is how the first three faces are processed for me:

 

[Quaoar]

a conditional breakpoint here for face 3 is not executed.

Now the question is why face 3 is never passed to asiAlgo_RecognizeEBF::Perform(). I think we can figure it out sooner or later, but it would require some patience and time
