Hello,
I have difficulties importing an idf file created with Sketchup.
The import goes mainly well, except for 3 surfaces (2 walls and 1 window, which belong to one of these walls), for which I got the following error message: "adjacent wall not found" and "adjacent window not found".
These walls are indeed interior walls. They are set as "ADJ_WALL", with "Outside Boundary Condition" set as "Zone", with the correct corresponding zone. And in the adjacent zone, the walls have the same construction, and the reciprocal zone set.
All vertices correspond exactly.
