I am trying to adjust the first floor subfloor level as my clients choice of joist supplier could not match my spec of an 11 7/8" joist instead using 14" and guess what, they already poured the foundation and I need to submit updated drawings for the changes. When originally drawn, the first floor subfloor was referenced at 0 above terrain int he settings. The terrain is acutally about 20" lower, however, witht he increased joist height, I need to move that reference up by 2 1/8". When changing the value in the terrain box, I get no change in the main floor subfloor height (still shows as 0.51m above reference grade of 0m, instead of 0.56m). Any clues as to how to move this up? I want the foundation to stay put as it is already in and I can't very well tell them to lower the footings by 2 1/8" can I lol.
Any help on this would be great - for now I think a cross section for the framer manually editing the reference geodetics may do the trick, but I need to get new plans done by the weekend. see the attached screenshot of my cross section and how the change in joist height messed up my footings instead of moving subfloor. (old plan with 11 7/8 joists on right)
