Description

Three-dimensional modeling system based on building plane design

Technical Field

The invention relates to the technical field of engineering automation design, in particular to a three-dimensional modeling system based on building plane design.

Background

In the field of building design, three-dimensional modeling is a widely used technique, and designers simulate the effect of building by creating a three-dimensional model and solve problems in design. Because the building design industry in China is characterized by short design period and frequent change, the frequent design content modification in the design process is a normal state, and how to efficiently complete the three-dimensional model adjustment under the condition becomes the key for popularizing the three-dimensional modeling technology.

In the prior art, designers input geometric information in a form of graphics or parameters to create three-dimensional members, and then assemble the three-dimensional members into a model. The difficulty of three-dimensional modeling is not only in creating a new three-dimensional model, but in reality most of the design time is not spent on creating a new three-dimensional model, but rather on modifying the model. The conventional three-dimensional modeling system for architectural design in the market comprises Revit, Archicad and the like, and the conventional three-dimensional modeling system for architectural design has more imperfect places due to application function limitation, and has the following main problems. One is as follows: synchronous modification can not be realized under the condition that the floor heights of the same floor model are inconsistent. The second step is as follows: one floor is only provided with a plurality of vertical surface line feet relative to other adjacent floors, but synchronous modification can not be achieved. And thirdly: the synchronous modification can not be realized under the conditions of the same house type model and different layer heights. Fourthly, the method comprises the following steps: if the line foot path difference is large, the contour can not be synchronously modified. And fifthly: the door frame and the window frame with the same outline can not be synchronously modified in outline if the door and the window are different in size. In summary, the existing three-dimensional modeling system software for building design directly applied to building design cannot meet the requirement of efficient modeling.

A wire-frame drawing paper range frame is created and set with a drawing name and a drawing positioning point through a wire-frame drawing paper range frame editing subunit. In the function of creating a new wire frame model in the wire frame model editing unit, the "create a wire frame model" button is clicked, and a single name is input to complete creation of a wire frame model (shown in fig. 3). The 'floor editing subunit' can provide a function of creating a 'floor list' for a page, can create a 'floor list' for each 'wire frame model', and can set a floor height for each 'floor'; the 'floor editing subunit' provides a function of associating 'wire frame drawing' for each floor; one floor may be associated with a plurality of "wire frame drawings" of different "drawing names", and one "wire frame drawing" may also be associated with a plurality of floors (shown in fig. 4, 5, 6).

As shown in fig. 1, 7, and 8, a wall line (representing the position of the actual wall line) is drawn in the page drawing range by the wall editing subunit, and for more intuition and flexibility, the following means are adopted to process the drawing: (1) enumerating the wall bodies with the common widths, setting a layer for each width of the wall body, setting the layers to be different colors, and setting the wall line color drawn on the layers to be set to follow the layer color, so that the wall bodies with different widths can present different colors; (2) the line widths of the wall bodies with different widths are set, so that the wall bodies with different widths have different thicknesses. A window line is drawn on a wall line through the window editing subunit to represent that a window is opened on the wall, the window line needs to be drawn on a window layer, the window line has two attributes of 'windowsill height' and 'window height' (a default value is provided), and after the window line is selected, the attribute can be adjusted in the attribute panel (shown in fig. 9 and 10). A section of door line is drawn on the wall line through the door editing subunit to represent that the door is opened on the wall, the door line needs to be drawn on the door map layer, the door line has two attributes of bottom height and door height (with default values), and the attributes can be adjusted in the attribute panel after the door line is selected (shown in fig. 11 and 12). Drawing a section of hole line on the wall line through the hole editing subunit to represent that a hole is formed in the wall, wherein the hole line needs to be drawn on the hole map layer, the hole line has two attributes of bottom height and hole height (with default values), and the attributes can be adjusted in the attribute panel after the hole line is selected (shown in fig. 13 and 14).

As shown in fig. 1, a floor is represented by drawing a closed multi-segment line in a drawing range of a floor editing subunit, the floor needs to be drawn on a floor designation layer, the floor has two attributes of "slab top" and "thickness" (has a default value), and the attribute can be adjusted in an attribute panel after the floor is selected (shown in fig. 15 and 16). The floor is represented by drawing a closed multi-segment line in the floor range through the descending board editing subunit, the descending board needs to be drawn on the specified layer of the descending board, and meanwhile, characters of the descending board height need to be placed in the descending board range, such as the ascending board 200, the content of the characters is "200", and the descending board 200 is "-200" (shown in fig. 17 and 18).

As shown in fig. 1, in the loft editing unit, a loft refers to a complex three-dimensional entity formed by using a contour as a section of a spatial path, and is mostly used for modeling of a decorative column, a facade decorative stitch, a door frame, a window frame, a bay window, and the like in a three-dimensional design of a building. In the present invention, to reduce the difficulty for the user, we split lofts into three categories: the vertical lofting body is a lofting body with a path being a straight line section and parallel to a Z axis, and is mainly used for decorating columns, special-shaped columns and the like. The horizontal sample body is a sample body with a path plane parallel to the XY plane, and is mainly used for outer vertical surface decoration line feet, convex window modeling and the like. The vertical sample placing body is a sample placing body with a plane where a path is perpendicular to a plane, and is mainly used for door frames, window frames and the like. A closed multi-section line is drawn in a drawing range by a vertical lofting body editing subunit to represent a lofting outline which needs to be drawn on a specified layer of the lofting outline; the lofting outline has two attributes of bottom height and height (default values), and the attributes can be adjusted in the attribute panel after the lofting outline is selected; to improve reusability, we can create the "loft outline" as a CAD block by the creating block function provided by AutoCAD software, copy the vertical loft in a single drawing or among multiple drawings by copying the CAD block, and modify the "loft outline" in other copies of the CAD block simultaneously (fig. 19 and 20).

As shown in fig. 1, a horizontal lofting profile frame is drawn by a horizontal lofting body editing subunit, a "horizontal lofting profile frame" is inserted in a drawing range, and a lofting profile drawn in the range of the "horizontal lofting profile frame" is recognized as a valid horizontal lofting profile; the positioning point is used for expressing the relative positioning relation between the intersection point and the lofting contour on the sectioning surface when the lofting body is sectioned by using a vertical plane relative to the plane of the horizontal lofting path as the sectioning surface; multiple "horizontal loft silhouette boxes" (shown in FIG. 21) may be placed within the same drawing sheet. Drawing a lofting contour through a horizontal lofting body editing subunit, drawing a closed multi-segment line within a range of a horizontal lofting contour frame by using a lofting contour drawing function to represent the lofting contour, wherein the lofting contour needs to be drawn on a specified layer of the lofting contour; the lofting contour in the horizontal lofting contour frame does not need to be provided with attributes; to improve reusability, we can create the "loft outline" as a CAD block by the creating block function provided by the AutoCAD software, copy the vertical loft in a single drawing or among multiple drawings by copying the CAD block, and modify the "loft outline" in other copies of the CAD block simultaneously (fig. 22). And drawing a horizontal lofting path through a horizontal lofting body editing subunit, drawing a section of multi-section line in a drawing range by using a lofting path drawing function to represent the horizontal lofting path, wherein the horizontal lofting path needs to be drawn on a specified drawing layer of the lofting path. The lofting path has two attributes of bottom height and turning path, and the attribute can be adjusted in the attribute panel after the line foot path is selected. The horizontal line leg paths and the horizontal lofting profiles in the same wire frame drawing are matched through colors, so that the situation that one horizontal line leg path corresponds to a plurality of horizontal lofting profiles can exist, the situation that a plurality of horizontal line leg paths correspond to one horizontal lofting profile can also exist, and the horizontal lofting paths and the horizontal lofting profiles are multiplexed through the flexible and visual mode (shown in fig. 23 and 24).

As shown in fig. 1, a vertical lofting profile frame is drawn by a vertical lofting body editing subunit, the vertical lofting profile frame is inserted into the drawing range, and a positioning point is built in the vertical lofting profile frame, and the positioning point indicates an intersection point of a vertical lofting path and a sectioning plane when a lofting body is sectioned by using a vertical plane corresponding to the plane of the vertical lofting path as the sectioning plane, and expresses a relative positioning relationship between the intersection point and the lofting profile on the sectioning plane. Only one vertical loft profile and a plurality of vertical loft paths (shown in fig. 25) can be contained in one vertical loft frame. And drawing a vertical lofting stitch path through the vertical lofting body editing subunit, drawing a vertical lofting path in the vertical lofting outline frame, wherein the starting point of the drawing path should use the positioning point of the vertical lofting outline frame as the starting point. After the drawing is completed, the vertical loft path is selected to set the "bottom height" parameter (with default) of the loft path (shown in fig. 26). The method comprises the steps that a vertical lofting profile block is drawn through a vertical lofting body editing subunit, a closed multi-section line is drawn by using a lofting profile drawing function to represent a lofting profile, the lofting profile needs to be drawn on a specified layer of the lofting profile, and the lofting profile does not need to be provided with attributes; in order to improve reusability, the lofting outline can be created into a CAD image block through a creating block function provided by AutoCAD software, the vertical lofting body can be copied in a single drawing or among a plurality of drawings by copying the CAD image block, and when the lofting outline in the CAD image block is modified, the lofting outline in other copies of the CAD image block can be modified synchronously; placing the CAD graph blocks in a wire-frame drawing range frame for plane coordinate positioning, and placing the same CAD graph blocks and the corresponding vertical lofting paths in the same vertical lofting outline frame; in addition, the CAD graph blocks also need to keep the same color with the corresponding vertical lofting paths; thus, multiple copies of the same CAD block can be provided in different colors and matched to the vertical lofting paths of different colors to form consistent and varying sized door and window frames (shown in fig. 27, 28, and 29).

As shown in fig. 1, a stair is created by a stair editing unit, all parameters of the stair can be completely set in a stair parameter editing window, a floor bench is created according to the floor height and the floor sequence, and then a series of parameters such as the step height, the step width, the tread thickness, the step number, the bench width, the shaft width, the platform width, the beam position and the like are set for each floor bench; after storage, the CAD model file is used to create a whole set of profile CAD blocks of the staircase and plane CAD blocks of each floor ladder. When the 'staircase' needs to be edited, the profile CAD graph block or the plane CAD graph block of the staircase can be double-clicked, the 'staircase' parameter is edited in the popped 'staircase parameter editing window', or the 'staircase' parameter is edited in the popped 'staircase parameter editing window' after the profile CAD graph block or the plane CAD graph block of the staircase is selected and the 'staircase' button on the drawing panel is clicked. When the "stair parameter editing window" is closed and stored, the profile CAD blocks or planar CAD blocks of the stairs in the CAD model file are also updated according to the parameter change (shown in fig. 30, 31, and 32). The stair positioning is realized through the stair editing unit, the plane CAD graphic blocks of the first floor (floor 1) of the stair are copied to the corresponding wire frame drawing of the first floor for positioning, after the stair refreshing positioning button is clicked, the stair plane CAD graphic blocks of the corresponding floors can be automatically inserted into the corresponding positions in the wire frame drawings of other floors, and if the relative positions of the upper layer and the lower layer of the stair plane CAD graphic blocks in the wire frame drawing are found to be incorrect, the positioning of the stair plane CAD graphic blocks in the wire frame drawing can be automatically adjusted (shown in figures 33 and 34).

As shown in fig. 1 to 34, under the combined action of the related unit modules, the invention can modify floor models with the same shape but different floor heights in batches, house models with the same shape but different floor heights in batches, vertical lofting bodies with the same lofting profile in batches, horizontal lofting bodies with the same lofting profile in batches, and vertical lofting bodies with the same lofting profile in batches. The advantages of the invention are embodied as follows. (1) The method includes the steps that (1.1) under the condition that a plurality of floor models are identical in batch modification scene, wherein the floor models are identical in shape and different in floor height, (1.1), identical 'wire frame drawings' do not need to be drawn repeatedly, and only one 'wire frame drawing' needs to be bound to a plurality of 'floors' when the 'wire frame drawings' are bound to the 'floors' (shown in fig. 35 and 36). (1.2) a plurality of floors exist in one model, the same floor is achieved, but only under the condition that a plurality of outer vertical face lofting bodies are added on the L level to serve as decorative models, in order to achieve multiplexing to the maximum degree, the outer vertical face lofting bodies added on the L level can be independently used as a wire frame drawing (a standard layer drawing), and other parts which can be multiplexed are used as a wire frame drawing (an L-level outer vertical face line foot drawing). When the 'floor' is bound with 'wire frame drawings', wire frame drawings 'standard layer drawings' are bound on the same floor, and wire frame drawings 'standard layer drawings' and wire frame drawings 'L-layer outer vertical face line foot drawings' are bound on the L layer; by distinguishing the same part from different parts in this way, the modification linkage of the same part can be ensured to the greatest extent, and the reusability of drawings (shown in fig. 37 and 38) is improved. (1.3) in the case that a model with the same floor contour exists in one model but the floor heights are different, in the modeling method, the same wire frame drawing is firstly bound to the floors, and then the floor heights are set to different height values, so that the case that the floor contour is the same but the floor heights are different can be realized (shown in FIGS. 39 and 40). (2) The vertical loft bodies with the same loft profile modify the loft profile scene in batches. (2.1) under the condition that a plurality of vertical lofting bodies are the same as the lofting outlines in a 'wireframe drawing', in order to ensure that the plurality of vertical lofting bodies which are the same as the lofting outlines in the 'wireframe drawing' can keep synchronization when the lofting outlines are modified, the 'lofting outlines' can be made into CAD (computer aided design) blocks, and then the CAD blocks are copied; when the lofting outline needs to be modified, if only the lofting outline in any CAD image block is modified, other same CAD image blocks can be modified synchronously. (2.2) under the condition that a plurality of wire frame drawings in one CAD model file share the modification scene of the vertical lofting bodies with the same lofting outline, in order to ensure that the vertical lofting bodies with the same lofting outline can be kept synchronous when being modified in the plurality of wire frame drawings in one CAD model file, the lofting outline can be made into CAD image blocks, and then the CAD image blocks are copied; when the lofting outline needs to be modified, as long as the lofting outline in any CAD image block is modified, the same CAD image blocks in other wire-frame drawings in the same CAD model file can be simultaneously modified. (3) Under the condition that a plurality of CAD model files share the vertical lofting bodies with the same lofting outline, in order to ensure that the vertical lofting bodies with the same lofting outline in the CAD model files can keep synchronization during modification, the lofting outline can be made into a CAD outline file, and then the CAD outline file containing the lofting outline is externally added into the CAD model files; when the 'lofting outline' needs to be modified, only the CAD outline file containing the 'lofting outline' needs to be modified, and all 'lofting outlines' in the CAD model file externally referring to the 'lofting outline' file can be simultaneously modified.

As shown in fig. 1-34, all "horizontal swatches" that are the same for (3) "loft profile" modify the scene in bulk. (3.1) under the condition that a plurality of different horizontal lofting paths in one drawing share the same lofting contour, in order to ensure that the plurality of horizontal lofting contours in one drawing are the same, but the horizontal lofting paths are different, and the horizontal lofting bodies are kept synchronous during modification, the horizontal lofting paths and a specified horizontal lofting contour can be set to be the same color; thus, the horizontal lofts comprising these "horizontal loft paths" share the designated "loft profile" which changes as the "loft profile" is modified. (3.2) under the condition that a plurality of drawings in one wire-frame model share the same lofting outline, in order to ensure that a horizontal lofting sample body with the same lofting outline can be kept synchronous when the lofting outline is modified in the plurality of drawings in one CAD model file, the lofting outline can be made into a CAD pattern block, and then the CAD pattern block is copied; when the lofting outline needs to be modified, as long as the lofting outline in any CAD graph block is modified, the same CAD graph blocks in other wireframe graphs in the same wireframe model can be simultaneously modified.

(4.2) under the condition that a plurality of wire-frame drawings in one wire-frame model share one lofting outline, in order to ensure that the same lofting outlines can be kept synchronous when being modified in the wire-frame drawings in one CAD model file, only the CAD image blocks containing the lofting outlines are copied; when the lofting outline needs to be modified, as long as the lofting outline in the CAD image block is modified, the lofting outlines in other same CAD image blocks can be modified synchronously. (4.3) under the condition that a plurality of CAD model files share one set of lofting outline, in order to ensure that the lofting outlines in different CAD model files can be kept synchronous during modification, CAD image blocks containing the lofting outlines can be made into one CAD outline file, and then the CAD outline file is externally added into the plurality of CAD model files; when the lofting outline needs to be modified, the lofting outlines in all CAD model files can be modified synchronously as long as the CAD outline files are modified.

(5.2) under the condition that a plurality of user-type blocks in a plurality of wire-frame drawings in one wire-frame model are shared and assembled, in order to ensure that a plurality of identical user-type blocks can be kept synchronous when being modified in a plurality of wire-frame drawings in one CAD model file, because the user-type blocks are already made into CAD image blocks or external reference files, only the CAD image blocks or external references are required to be copied; when the 'house type block' needs to be modified, the same 'house type block' in other 'wireframe drawings' in the same CAD model file can be simultaneously modified. (5.3) under the condition that the 'house type blocks' among the CAD model files are shared and spliced, in order to ensure that the 'house type blocks' in different CAD model files can keep synchronous during modification, the content of the 'house type blocks' can be made into a CAD house type block file, and then the CAD house type block file is externally added into the CAD model files; when the 'house type block' needs to be modified, as long as the content of the 'house type block' in the external reference file is modified, the content of the 'house type block' in the CAD model file of all the external reference CAD house type block files can be synchronously modified.

(6.1) under the condition that one 'wire frame model' contains a plurality of same 'stairs', placing a CAD (computer aided design) graphic block of a first-layer stair plan of the 'stairs' into a 'wire frame drawing' corresponding to the first layer of the 'wire frame model', if the 'stairs' have a plurality of same stairs in the 'wire frame drawing', only copying or mirroring the CAD graphic block of the first-layer stair plan and then placing the CAD graphic block at a corresponding position; when the stairs are modified, all the same stairs are modified synchronously. (6.2) under the condition that a plurality of CAD model files share a stair, in order to ensure that the stairs in different CAD model files can be kept synchronous during modification, the stair can be made into a single CAD stair file, the CAD stair file is externally added into each CAD model file, the positioning operation of the stair is completed in a wire frame drawing of each CAD model file, and once the content of the stair in the CAD stair file is modified, the stairs in all the CAD model files can be automatically updated.
