I’ve been taking my first tentative steps into the world of worksheets. I’ve made a worksheet that reports on material quantities in walls using the COMPAREABYNAME function. In the case of timber cladding/siding I then convert the sqm total into a linear metre value based on the type of cladding/siding being used. So in the case of 200mm featheredge board (bevel edge siding) I multiply the sqm in a separate cell by 5.71 which gives me the total linear metres for the cladding. Hurrah!
