Does the engineer draw on cad? I beleive that it is the responsibility of the one who modified the cad file to place the rev. cloud around the area of change, if it is on a set issued after the construction set. Does the engineer tell the draftsman what layer to draw objects on, or is it a given?
Our office is a bit differnt, we are all designers, we design, draft and redline, and do a bit of light engineering, then our 2 architects review, and comment or stamp. We send it out of office to be engineered, if it's not straight foward.
