In the loft editing unit shown in fig. 1, the loft refers to a complex three-dimensional entity formed by taking a contour as a section of a space path, and is used for modeling decorative columns, outer-elevation decorative line feet, door frames, window frames, protruding windows and the like in three-dimensional design of a building. In the invention, in order to reduce the difficulty of a user, the lofting body is split into three types: the vertical lofting body refers to a lofting body with a straight line section and parallel to a Z axis, and is commonly used for decorative columns, special-shaped columns and the like. The horizontal lofting body is a lofting body with a path plane parallel to the XY plane, and is mostly used for outer elevation decorative line feet, protruding window modeling and the like. The vertical lofting body is a lofting body with a plane where a path is located and perpendicular to the plane, and is mainly used for door frames, window frames and the like.

The lofting path has two attributes, namely a bottom height attribute and a flip path or not (with default values), and the attributes can be adjusted in the attribute panel after the terminal path is selected. The horizontal line foot paths and the horizontal lofting outlines in the same piece of line block paper are matched through colors, so that the situation that one horizontal line foot path corresponds to a plurality of horizontal lofting outlines can exist, the situation that a plurality of horizontal line foot paths correspond to one horizontal lofting outline can also exist, and the mutual multiplexing of the horizontal lofting paths and the horizontal lofting outlines is realized in a flexible and visual mode (shown in fig. 23 and 24).
In fig. 1, a vertical lofting outline frame is drawn by a vertical lofting body editing subunit, a positioning point is inserted into a drawing range, and the positioning point represents an intersection point of a vertical lofting path and a section surface when the lofting body is sectioned by using a vertical plane relative to a plane where the vertical lofting path is located as the section surface, so that the relative positioning relation between the intersection point and the lofting outline on the section surface is expressed. Only one vertical loft profile and multiple vertical loft paths can be included in a single vertical loft frame (shown in fig. 25). And drawing a vertical lofting line foot path through a vertical lofting body editing subunit, drawing a vertical lofting path in a vertical lofting outline frame, wherein the starting point of the drawing path takes a positioning point of the vertical lofting outline frame as a starting point. After the drawing is completed, the vertical loft path is selected to set the "bottom height" parameter (with default value) of the loft path (shown in fig. 26). Drawing a vertical lofting outline block through a vertical lofting body editing subunit, drawing a section of closed multi-section line by using a function of drawing the lofting outline to represent the lofting outline, wherein the lofting outline is required to be drawn on a designated layer of the lofting outline, and the lofting outline is not required to be provided with attributes; in order to improve reusability, the "loft profile" can be created into a CAD block by a creation block function provided by AutoCAD software, the vertical loft body can be copied in a single Zhang Tuzhi drawing or among multiple drawings by copying the CAD block, and when the "loft profile" in the CAD block is modified, the "loft profile" in other copies of the CAD block can be synchronously modified; placing the CAD graph block in a line block paper range frame for plane coordinate positioning, and placing the same CAD graph block and a vertical lofting path corresponding to the same CAD graph block in the same vertical lofting outline frame; in addition, the CAD image block also needs to keep the same color with the corresponding vertical lofting path; thus, multiple copies of the same CAD block may be provided in different colors and matched to different color vertical loft paths to form uniform contoured, different sized door and window frames (shown in fig. 27, 28, 29).
As shown in fig. 1, a "stair" is created by a stair editing unit, all parameters of a "stair" can be completely set in a stair parameter editing window, first a "floor bench" is created according to a "floor height" and a "floor sequence", and then a series of parameters such as step height, step width, kick face thickness, tread face thickness, step number, step width, step well width, platform width, step beam position and the like are set for each "floor bench"; after the storage, a section CAD graph block of the whole stair and a plane CAD graph block of each floor bench are created in the CAD model file. When the stair is required to be edited, the stair parameter can be edited in the popped stair parameter editing window by double-clicking the profile CAD block or the plane CAD block of the stair or by selecting the profile CAD block or the plane CAD block of the stair, and the stair parameter can be edited in the popped stair parameter editing window after clicking the stair editing button on the drawing panel. When the "stair parameter editing window" is closed and saved, the profile CAD image or the plane CAD image of the stair in the CAD model file is updated according to the parameter changes (shown in fig. 30, 31, and 32). The stair editing unit is used for realizing the positioning of a stair, a first-layer (1-floor) plane CAD (computer aided design) block of the stair is copied into a line block diagram paper corresponding to the first layer to be positioned, after a stair refreshing positioning button is clicked, the stair plane CAD block of the corresponding floor can be automatically inserted into the corresponding position in a line block drawing of other floors, and if the relative positions of the upper layer and the lower layer of the stair plane CAD block in the line block drawing are found to be incorrect, the positioning of the stair plane CAD block in the line block drawing can be automatically adjusted (shown in figures 33 and 34).

The advantages of the invention are embodied as follows. (1) In the case where a plurality of floor models are identical in one model, the same "line drawing" is not required to be drawn repeatedly, and only one "line drawing" is required to be bound to a plurality of "floors" at the same time when the "floor" is bound to the "line drawing" (shown in fig. 35 and 36). (1.2) a model has a plurality of floors which are the same as one touch, but only under the condition that L layers are more than a plurality of facade loft bodies as decorative modeling, in order to realize multiplexing to the greatest extent, the L layers of the facade loft bodies can be independently used as a piece of wire frame drawing 'standard layer drawing', and other reusable parts can be used as a piece of wire frame drawing 'L-layer facade line foot drawing'. When the floor is bound with the wire frame drawing, the standard layer drawing of the wire frame drawing is bound with the same floor, and the L layers are simultaneously bound with the standard layer drawing of the wire frame drawing and the L-layer outer elevation line foot drawing of the wire frame drawing; by dividing the same part into different parts in this way, the modification linkage of the same part can be ensured to the greatest extent, and the reusability of the drawing (shown in fig. 37 and 38) can be improved. (1.3) in the case that a model with the same floor profile is present in one model, but the floor heights are different, in the modeling method, the floors are firstly bound with the same wire frame drawing, and then the floor heights are set to different height values, so that the situation that the floor profiles are the same in one model but the floor heights are different can be realized (shown in fig. 39 and 40).
