I'm not sure what you are referring to. Is this a question about the FSDT Honolulu scenery running in FSX/P3D ? There's no way the FS9 version will ever run under it, but it's not an issue, since we have a native FSX/P3D version available.
If, instead, you are referring to the old AFCAD utilities by Lee Swordy, and are asking if they could be used in FSX/P3D, I'm not sure how this question has any relationship to the FSDT Honolulu for FS9 support forum...
However, in FSX/P3D, people use ADE (freeware) or AFX (commercial), to edit AFCADs.
