adding more than one assembly to a backplate in visualise standard

  1. I open a new project in visualise 2024 standard.
  2. import a new backplate (a room scene)
  3. I open project, model, import model and select an assembly (this pops onto the screen)
  4. I repeat point 2 to import another model. 
  5. the 2nd model merges with the first imported model and I cant position then in room scene separately.

 

I'm trying to create a room scene where I position multiple items of furniture and hope there is an way around this merging issue.
