See figure 1 for a general frame diagram. The method is characterized in that floor room information is acquired from a Revit floor plan, is stored in a database, and is marked by utilizing a coordinate matching algorithm in a three-dimensional model room. The method comprises the following specific steps:
step one: accessing building elements through a Revit API interface in a Revit floor plan, creating a filtering collector and filtering conditions, and storing a Room into the collector;
step two: converting the Transform function coordinates into a unified model coordinate system by each floor ROOM primitive component, positioning the Revit.location function coordinates to obtain coordinate data of the boundary outline of the ROOM area, and obtaining the ROOM NAME and ID character string information by using the Revit API built-in parameter building InParameter ELEM_ROOM_NAME;

Mode two: the Element Geometry function is used to obtain the point, plane and line space positioning of complex graphic primitives. For example: stairs, roof, inclined wall.
In a second embodiment, parameters identifying the room and the coordinates of the boundary of the closed room are obtained through the Revit API in the Revit floor. The primitive component element is a condition of a room boundary, and for the element of the model curve, the class of the primitive component element is building InCategory; for other elements, such as walls, columns, their ROOM boundary (buihinparameter. WALL_ATTR_ROOM_BOUNDING) parameter must be set to True.

in the Revit three-dimensional view, model annotation information is obtained through a Revit coordinate data matching algorithm, and the coordinate data information algorithm in the middleware is matched: determining a model room to be marked, taking any point A in the model room, and obtaining a spatial coordinate system (x i ,y i ,z k ) Let z k Representing the height of the floor (x) i ,y j ) Representing the position in the floor room, according to z k Judging the floor range in the floor plane to which the floor ID belongs, thereby obtaining the floor ID; and then respectively making x-axis and y-axis vertical lines on the point A in the xy plane according to (x i ,y j ) The range of the rectangular coordinate system for obtaining the floor ID can be accurately judged by matching with the data in the middleware file, so that the name and ID of the whole model room can be obtained.
