If all the dimensions are on the plan somewhere, in some form, then the contractor has all the necessary information. There are Different Types of Construction Drawings in construction serve as the guide to the site engineer in charge and give detailed information like size, dimensions, material, and location of a component of the structure. But avoid setting a BIM dimension style that automatically rounds your dimensions to, say, the nearest inch. Dont get me wrong: I think Revit is a wonderful modeling software that does amazing things. Dimension lines are lighter than line weights used for walls and structural elements. Column Lines General Drawing Layout Dimension lines Dimension lines are used to indicate the distance between two points.
