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.](https://discourse.vtk.org/t/lesson-2-import-iges-step-files-while-using-vtk-visualization-simple-example/7991)]

Lesson 17  
[[Lesson 17.1: Point Membership Classification with OpenCascade + VTK](https://discourse.vtk.org/t/lesson-17-1-point-membership-classification-with-opencascade-vtk/8009)]

A problem that I solved and have a solution and will upload the solution.  
[[Cascade appanding -TopoDS\_Shape- to -vtkAppendPolyData- or -vtkCleanPolyData- or simply convert -TopoDS\_Shape- to -vtkPolyData- NOT WORKING - #3 by anon41080341](https://discourse.vtk.org/t/cascade-appanding-topods-shape-to-vtkappendpolydata-or-vtkcleanpolydata-or-simply-convert-topods-shape-to-vtkpolydata-not-working/7967/3)]
