Composite wall, existing and new construction skin?

[Anonymous]

I'm doing a renovation and there should be thermal insulation added to existing exterior walls. As I have to make two plans - existing and after renovation, the thermal insulation should not be visible in the existing plan, but how to do that using renovation filters?

Please post separate questions in separate post.
I have split them into separate posts.

For this you will need an 'existing' wall without the insulation and a 'new' wall with the insulation.
Use the filterers to "Hide" the existing or new wall as required.

Unfortunately we can not have just a new skin for a wall - you have to replace the entire wall.
