Hello All 

can someone please let me know if you can Associate wall heights with cabinets for example i have a wall 2400mm high with a 20mm shadowline so my cabinet from FFL to top of cabinet = Wall height -20mm. when we do site measure  the wall height then changes to 2430mm. im just doing a alot of apartments and need to change to site measures and i find their must be a good way to Associate wall heights into products somewhere with out adding global viables all the time.
