Hello  
I have a CFD postprocessing task with \*.plt file as surface data source. After the surface data was imported via vtkTecplotReader, I tried to cut a slice at the symmetry boundary plane (Y=0 ) with “vtkCutter”. However, the slice turned to be empty with no point or cell data. Should I try another interpolation algorithm to get correct slice data at that boundary plane?

This is my code:  
:

> vtkNew\<vtkPlane\> plane;  
> plane-\>setOrigin(0,0,0);  
> plane-\>setNormal(0,1,0);  
> vtkNew\<vtkTecplotReader\> reader;  
> reader-\>setFileName(“xxx.plt”);  
> reader-\>Updata();  
> vtkNew\<vtkCutter\> cutter;  
> cutter-\>setCutFunction(plane);  
> cutter-\>Updata();

Thanks !  
Best Regards
