P3D v4 Object placement tool for p3dv4

Hi, is there available a visual object placment tool for P3d v4? Good old Whisplacer worked well in p3d v3, but now the whisplacer says it cannot connect simulator something ipv6 is not compatible. Now i need same type program for p3d v4 so i can keep building my own city sceneries, Whisplacer was good, because i could visually add buildings into sim for their right places etc.
At this moment we are using P3DV4.5.

When I chokes Scenery, I am Gatting the subcategories. However, nothing is showen in the Showing window below it.
I can see the objects in the main window...

Am I doing something wrong ?

Advice is appriciated.

Thanks, Gerard
