There are two parts of this video. Part1 ( between 0 to 1 mins 13 sec) shows that you can export the wall type information in CSV(Excel) file. If you change the wall type and import back the excel file, it will automatically highlight changed walls.
Part2 (between 1min 13 secs to end) shows that you can export the wall structure information. This will export the layer thickness in excel file. If you make changes in wall layer thickness and import back the original excel file, it will highlight those walls which have different layer thickness as compared to the excel file.
