Plinth Beam Layout Dont get me wrong: I think Revit is a wonderful modeling software that does amazing things. Even a plan that follows all the above tips can still look ugly and messy. For instance, a C with an L through it is a center line, and describes that a window is centered, with equal distance on either side. Numbering the grid line by a,b,c.. or 1,2,3.. Serially. You can read the description as circled in red as the electrical panel number and the circuit in that panel, such as; P5-16 (Panel 5, Circuit 16).This indicates that VAV 1-5 has electrical conduit and wire coming from panel 5 and circuit #16 in that panel.

Column center lines are the starting points for all strings of dimensions [3]. The purpose of dimensioning, like every other aspect of the construction drawings, is to give the contractor just enough information to build the project, andideallynot a bit more than that. Single lines are used for displaying the interior part of the walls, while external walls are drawn as thick and weighty double lines. Elevation marker labels can be number or letters, or relate to the orientation of the elevation, ie north south east or west. Gridlines align to the outer edge of external wall framing, to the center of internal wall framing, to the center of primary columns, and may align to the edge of slab. In most cases, they arent, so just locate one face of each partition to its nearest column line. Two cases where clear widths are often critical: (1) means of egress (e.g., stairs and corridors), which are governed by building codes; and (2) toilet rooms, where accessibility dimensions are governed by ADAAG or building codes. Always keep in mind, annotation and labelling are to ensure clarity of the drawing. Most important dimensions, the ones that really matter, are nice round numbers, usually to the nearest inch.
