Convert fixed tilted table into domes in 3D scene

[Toni]

Hi,

 I am struggling with a rather simple problem but is it possible to convert a field with fixed tilt tables directly into domes or tracker ?

When I change from fixed tilt to domes in the orientation menu and afterwards try to fill out the zone in the 3D scene, the zone is again filled with fixed tilt tables, even if I change the orientation in the 3D workspace.... Is there another approach how to? 

When I do the changes in the 3D scende first, I get the error that there's no field 

Any helping advice would be welcome 

Kind regards, Toni

P.S.: I am using PVsyst vers. 8.0.13
