Dear @cory.quammen
Is this the Proper way to publish Code ?
Thank You. :pray:

In this example, I am adding Import .Iges file and .Step File to this YouTube Video Example
[Lesson 2: Bring OpenCascade and VTK together - YouTube]

add this to includes

#include <IGESControl_Reader.hxx>
#include <STEPCAFControl_Reader.hxx>

add this to main


//STEP
STEPControl_Reader readerSTEP;
IFSelect_ReturnStatus statSTEP = readerSTEP.ReadFile("C:\\WorkSpace\\prism.step");
IFSelect_PrintCount modeSTEP = IFSelect_ListByItem;
readerSTEP.PrintCheckLoad(Standard_False, modeSTEP);
TopoDS_Shape shapeSTEP = readerSTEP.OneShape();

//IGES
IGESControl_Reader ReaderIGES;
IFSelect_ReturnStatus statIGES = ReaderIGES.ReadFile("C:\\WorkSpace\\prism.igs");
IFSelect_PrintCount modeIGES = IFSelect_ListByItem;
ReaderIGES.PrintCheckLoad(Standard_True, modeIGES);
ReaderIGES.TransferRoots();
TopoDS_Shape shapeIGES = ReaderIGES.OneShape();

fix in the correct line in main

vtkNew<IVtkTools_ShapeDataSource> occSource;
occSource->SetShape(new IVtkOCC_Shape(shapeIGES));//shapeSTEP //shapeIGES

good luck!

Dear @cory.quammen @mwestphal
I know this is the wrong place to send mail.
But, the truth is, that I could not find where to send regular mail, on this Platform.

As you can see, In my Uploaded code, I have connected VTK to one of the Newest and clearest,
Open Cascade on YouTube.

Plus, How to Import .IGES .STEP files,
So an engineer can start work Directly on complex Mesh, at the same level as Solid Works!

Here in Lesson2 from YouTube.
[Lesson 2:Import .IGES .STEP files while using VTK visualization ,simple example.]

Lesson 17
[Lesson 17.1: Point Membership Classification with OpenCascade + VTK]

A problem that I solved and have a solution and will upload the solution.
