When dimensioning  I would like to know if there is a standard. For example on a large scale unit plan what is commonly dimensioned to for a brick-block cavity wall with steel studs on the interior with drywall. My large scale plan is part of a set of plans for a 6 storey apartment building. I am not sure what I should actually dimension as far as detail in the wall. Is there a standard for this?ChrisH2008-03-18 15:42:19
