Summary0023950: Names and visibility of points not saved when writing XCAF Document into STEP
DescriptionAs stated in the subject the visibility and the name (located at the corresponding label) of points is not written into the STEP file when using STEPCAFControl_Writer.

This happens if points are located in the assembly structure (i.e. "SimpleShape is not FreeShape").

In case of edges and other shapes this problem does not occur. Only points seem to be affected.
Steps To Reproduce//test_point_assembly.step
TopoDS_Shape s6 = BRepBuilderAPI_MakeVertex(gp_Pnt(75,0,0));
gp_Trsf t0;
TopLoc_Location location0(t0);

TDF_Label lab1 = XCAFDoc_DocumentTool::ShapeTool (aDoc->Main ())->NewShape();
XCAFDoc_DocumentTool::ShapeTool (aDoc->Main ())->SetShape(lab1, s6);
TDataStd_Name::Set(lab1, "Point1");

TDF_Label labelA0 = XCAFDoc_DocumentTool::ShapeTool (aDoc->Main ())->NewShape();
TDataStd_Name::Set(labelA0, "ASSEMBLY");
        
TDF_Label component01 = XCAFDoc_DocumentTool::ShapeTool (aDoc->Main())->AddComponent(labelA0, lab1, location0);
        
Quantity_Color yellow(1,1,0, Quantity_TOC_RGB);
XCAFDoc_DocumentTool::ColorTool (labelA0)->SetColor(component01, yellow, XCAFDoc_ColorGen);
XCAFDoc_DocumentTool::ColorTool(labelA0)->SetVisibility(component01, 0);

STEPControl_StepModelType mode = STEPControl_AsIs;
STEPCAFControl_Writer writer;
if ( ! writer.Transfer (aDoc, mode ) )
{
    cout<<"The document cannot be translated or gives no result."<<endl;
    return;
}

IFSelect_ReturnStatus stat = writer.Write("test_point_assembly.step");
=========================

The name "Point1" cannot be found in the resulting STEP file. "INVISIBILITY" does not occur either.

Dear Pawel,

According to issue OCC725 (Storing all free vertices of STEP into one SHAPE_DEFINITION_REPRESENTATION), all free vertices are exported like one geometric curve set, so a single vertex can't has its own color, name etc.

Dear ika,

if this behaviour is desired, please leave it as it is and close the issue.

Unfortunately, I don't have the access to the issue 725. Why is it desired to always have all free vertices as one SHAPE_DEFINITION_REPRESENTATION?

Issue #725 gives no explanation, it was just request to have all free vertices in one SDR :)

I deem that names of the points can possibly be encoded in their corresponding entities. Regarding colors, visibility, and other attributes, it would be worth checking current status of relevant Recommended Practices at CAX-IF web site to see whether this is supported for points by STEP APs or not, and how to encode it if supported.

New mode of vertices writing was added, but old behavior is default.
A parameter "write.step.vertex.mode" was added to switching between these two modes:
0 - "One Compound" - old behavior (by default),
1 - "Single Vertex" - new behavior.

Branch CR23950 is ready to be reviewed.
Dear GKA,
Please review.

Dear MKV,

As I wrote before, old behavior is default, and new vertex writing mode is additional and switch on by parameter write.step.vertex.mode. So BAD result in default mode is correct. To get IMPROVEMENT result this parameter should be 1 (0 by default).

I correct test script by switching ON/OFF this parameter. Now the result of test case is IMPROVEMENT.
