Hi Andras,  
I am saving PLY file but it is still saving STL file.

I am saving the segments using

```
slicer.modules.segmentations.logic().ExportSegmentsClosedSurfaceRepresentationToFiles("/home/saima/2021_5_28/slicer work/modelFiles/", segmentationNode, None,"PLY", True, 1.0, False )

```

The function saves as stl not ply

This method supports STL and OBJ - see [documentation](http://apidocs.slicer.org/master/classvtkSlicerSegmentationsModuleLogic.html#a4b5328985b2d98cbbc93a5b2ae7fde6b). You can export to PNG by exporting the segmentation to model nodes and then save the model nodes to files.
