Doors

 Doors are generally classified by their action,as illustrated in and whether they are interior or exterior units.Although a wide variety of styles exists within these general classification,it is difficult to denote the specific style in a plan view.Refers to chapter 10 for the most common door types,their operation,styles,hardware,and other features.Doors are drawn in plan view as a hardware ,and other features.Doorsare drawn in plan view as a heavy line in small-scale drawings,or as a double line,to indicate their thickness,in larger-scaled plans.A swing door has a thinner curved line drawn to denote the direction of its swing.In small projects (particularly residential work) the door size is noted on the plan. 

   In larger and commericial projects,openings that are to receive doors can be addressed by two methods.The first and simplest is to treat openings generally.Doors might be labeled "A," for example and all be of the same type.Finish frame,and hardware."B" doors would represent another group.The other method is to address each opening as a unique design feature and deesign each door its own independent number,as shown in it.A circle is drawn withine the door swing,and the door number is placed withine it.In trun,this number is referenced to a door schedule that provides the details for that distinct door.This information is then cross-referenced to a door schedule,as explained in last blog.

  Doors and windows in plan view are generally dimensioned to the centerline of the door or window and frame unit,as shown in it.This method allows the designer to locate the door fairly accurately,leaving the actual rough opening,trim,and other   

                                                    

                          

clearance details to the builder.In masonry,the door or window assembly (which has an exact unit size )is listed.The builder provides (in both cases ) a slightly larger size,to set and shim the unit to fit the opening.The rough opening size is listed on the plan or in the schedule and abbrevlated "R.O." This R.O. includes the door,frame,and proper clearances to install the unit within the frame wall,as illustrated in it.In many cases where a door hinge is close to an adjacent wall,it is not necessary to dimension the center of the door (or frame).The builder knows the door is to be located light to the wall and will allow the proper exact clearances for opertaion and trim work,as shown in above figure.     

Other dimension noted on the plan will govern the size of the rooms,as it controls the exact placement of the studs.The finishes placed over the studs reduce the dimensions of the room by the material thickness.Some materials such as ceramic tile have an uneven base,which varies the rooms dimension slightly.

  Various notes are also added to the floor plan to convey specific information to the client or builder.These items might include handrails on stairs,soffits above,floor-level changes,and so forth,as shown in it.However,these notes are kept to a minimum in order not to clutter the drawing and are lettered at a smaller height than the room names.Shows an example of how notes might be added to floor-plan drawings.
