Greetings: I have updated to X17 from C10 recently after using C10 for over 20 years. Most of my designs are on pilings set at 96" height with a 12" girder on top. I use 14" floor trusses on top of the girder so the first finished floor is 122.75" from grade. The problem I am encountering is the siding for the first floor stops at the finished floor. I am trying to extend the siding down 14.75" to cover the floor trusses. I was chatting on open AI last night but could not find the resolution to filling the open gap for the floor truss location. From what I gathered this is a common problem when importing files from older versions of Chief. Any help or suggestions are greatly appreciated. Thank You! Glenn Willis
