Dear Milinda,

As far as I know, WNT_GraphicDevice is no longer part of the package TKService in OpenCASCADE 6.6.0. I would suggest you to read the release notes of OCCT 6.6.0 here:

Page 31 describes shortly how to initialize a graphic device in the new versions.

If you want to see how it works in practice, you can check the sample project in the "Samples" folder of your OpenCASCADE package.

Best regards
