someone of you have some way to do the export in an objet to use in powerpiont
If you mean as interacting with a 3D object? If you make segmentation and export your segmentation as PLY/OBJ/STL, you should be able to import that model into newer versions powerpoint.
If you mean 2D capture, you can either use the screen capture or scene view tools of Slicer (the little camera icons on the toolbar) and save them as PNG/JPG etc…
You may find documentation of Screen Capture module useful: https://www.slicer.org/wiki/Documentation/Nightly/Modules/ScreenCapture
