Thank you but unfortunately that doesn't solve the issue, I probably should have been more clear on my first post. The issue is the detail at low level in 2019 and 2020 are completely different. Is there any way to change this and keep wall components hidden without having to change each door? (areas that have changed indicated by red arrows) We would like to be able to replicate 2019 low level detail in 2020, at the moment we are having to export back to 2019 just to achieve this.
