The terminal may include a processor, memory, screen, etc. The processor may be a CPU (Central Processing Unit ) or the like, and may be configured to receive instructions, perform related processing such as drawing and labeling, and control the display to perform processing such as display. The memory may be RAM (Random Access Memory ), flash (Flash memory), or the like, and may be used to store read data, data required for a processing procedure, data generated during a processing procedure, or the like, such as information data, system data, control pages, or the like. The screen may be a touch screen, may be used to display control pages, etc. The terminal may also include input means, such as a keyboard, a mouse, etc. of a computer terminal, which may be used for operating the terminal, for example, inputting instructions to the terminal, writing data, etc.
As shown in fig. 1, the process flow of the method may include the following steps:
and step 101, acquiring a three-dimensional model diagram of the civil engineering structure.
In practice, an engineering technician may draw an engineering drawing (i.e., a target two-dimensional representation) of the building structure to be built, and then submit the target two-dimensional representation to a constructor for construction. Specifically, the engineering technician may draw a three-dimensional model of the building to be built (i.e., a three-dimensional model of a civil engineering structure) on a three-dimensional design platform on the terminal, and then obtain the three-dimensional model of the civil engineering structure built in the three-dimensional design platform, for example, the three-dimensional design platform may be three-dimensional design software such as AVEVA-PDMS (factory three-dimensional layout management system VANTAGE Plant Design System), solidWorks, SP3D (SmartPlant 3D), and the like. The method comprises the steps of acquiring a three-dimensional model of a civil structure built in a three-dimensional design platform, and designing and acquiring the three-dimensional model of the civil structure from the three-dimensional design platform, or directly acquiring the three-dimensional model of the civil structure in a related file stored in the three-dimensional model of the civil structure.
And 102, analyzing the three-dimensional model of the civil structure to obtain object information of each object, and storing the object information into a pre-defined data structure according to the hierarchical relationship and the connection relationship of each object and storing the object information as information data of the three-dimensional model of the civil structure.
In implementation, as shown in fig. 2, the three-dimensional model of the civil structure is parsed to obtain object information such as names, sizes and the like of objects in the three-dimensional model of the civil structure, and meanwhile, the object information includes a hierarchical relationship, and the hierarchy of the three-dimensional model of the civil structure includes a civil structure integral set, a civil structure region set, a member, a floor slab and an attachment.
As shown in fig. 3, a data structure including the hierarchical relationship of the above-mentioned civil structure including the axis network information is defined in advance by a program language, the three-dimensional model of the civil structure obtained in step 101 is parsed, and the parsed data is stored in the defined data structure of each hierarchy. The axis net information refers to axis information of x-axis, y-axis, z-axis in the three-dimensional platform and a positioning axis in the three-dimensional civil structure (a center line of a beam, a wall, or a column, or other lines that may be used to represent the positioning axis in the three-dimensional civil structure). The information data of the analyzed three-dimensional structure model comprises shaft network information, integrally combined identification information, integrally combined position information, civil structure area combined identification information, position information and the like, and the identification information and the position information of each level of the civil structure three-dimensional model are included; in addition, the information data of the resolved three-dimensional structure model also comprises the topological relation between the component and the accessory contained in the component and the topological relation between the floor slab and the accessory contained in the floor slab.
After the data structure of each level of the civil structure three-dimensional model is defined by adopting a program language, the concrete process of storing information data can be to sequentially scan the civil structure three-dimensional model according to the levels, acquire related information and store the related information in the defined data structure. The information stored in the data structures of each level of the three-dimensional model of the civil structure in step 102 is stored in an independent database, or may be converted into an intermediate file in the form of an XML file or the like, and the converted intermediate file is stored in the independent database as information data of the three-dimensional model of the civil structure, for example, the database may be an MS SQLSever2015 database. In computers, the data may be stored in the form of a data table, as shown in Table 1
Table 1 tables in database
Taking the three-dimensional model of fig. 2 as an example, the model comprises 4 concrete columns (column-001-column-004), 4 concrete beams (beam-001-beam-004) and 1 floor slab (floor slab-001). 1 concrete bracket (N30-3050) is arranged on each of the column-001 and the column-002, and 1 steel beam (beam-005) is arranged on each bracket; the beam-001 side has 1 lug (TR 250×400); two ends of the beam-004 are provided with 2 horizontal haunching plates, 1 steel plate embedded part (M3520B 2) is arranged in the middle of the beam-004, and a floor slab-001 is provided with 1 hole with the diameter of 1500 mm.
Its table and header in the database is shown in table 2:
table 2 tables and headers in a database
The civil structure three-dimensional model comprises 1 whole collection table (comprising 1 data record), 1 region collection table (comprising 1 data record), 1 component table (comprising 9 data records), 1 floor table (comprising 1 data record), 1 bracket table (comprising 2 data records), 1 ear picking table (comprising 1 data record), 1 haunching table (comprising 2 data records), 1 buried table (comprising 1 data record), and 1 hole table (comprising 1 data record).
And step 103, importing the information data of the three-dimensional model of the civil engineering structure into a drawing platform.
In practice, the drawing platform may be opened and then the information data of the three-dimensional model of the civil structure stored in the database is imported into the drawing platform. For example, as shown in fig. 4, the import process of the model is that a three-dimensional model of a civil structure generated on a three-dimensional design platform AVEVA-PDMS (or a three-dimensional drawing platform such as SP 3D) is stored in a data structure defined by c# or c++ language or pml.net language, etc., then information in the data structure is stored in a separate database, or is converted into an intermediate file such as an XML file to be stored in the separate database, a CAD (computer aided design ) is opened, and then information stored in the database is imported into the CAD through a model conversion interface.
Alternatively, the drawing information of the drawing plane of the drawing platform may be determined after the information data is imported into the drawing platform, and the specific process may be as follows: and determining drawing information of the drawing platform, wherein the drawing information comprises an effective display range and an effective drawing range of the target two-dimensional expression drawing on the drawing platform.
In implementation, the engineering technician can set or select the drawing information such as the dimension (i.e. the effective display range) and the effective dimension (the effective drawing range) of the drawing by displaying the drawing setting interface, for example, the page type or the effective proportion can be displayed, the user can set the drawing information by inputting the relevant dimension, the paper types A3, A4 and the like can also be directly displayed, and the user directly selects the paper type to obtain the corresponding drawing size. The effective display range is slightly larger than the effective drawing range, so that drawing staff can intuitively know the size of the target two-dimensional expression diagram on a drawing in the drawing process or the labeling process, and further the target drawing range or drawing information is adjusted.
And 104, acquiring two-dimensional symbol and legend information corresponding to intersection content in the drawing platform.
In the implementation, after the information data of the three-dimensional model of the civil structure is imported to the drawing platform, the data in the information data and the database of the drawing platform can be searched, and two-dimensional symbols and legend information (the two-dimensional symbols and the legend information are also collectively called as two-dimensional legend symbols in engineering) corresponding to object information in the three-dimensional model of the civil structure are obtained, wherein the two-dimensional symbols are representation symbols when the target object in the three-dimensional model of the civil structure corresponds to the two-dimensional platform; the legend information value refers to annotation information including information of names, lengths and the like corresponding to the object. For example, a column in a three-dimensional model of a civil structure may correspond to a double vertical line of 3 lbs. of two-dimensional symbol in two-dimensional space, and the legend information obtained may be a column, 5 units. The resulting two-dimensional symbol and legend information is stored in object information in the information data. The two-dimensional symbol and legend information on the drawing platform can be preset and stored by engineering technicians, for example, the two-dimensional symbol and legend information can be divided into a plane view style sheet, an X section view style sheet and a Y section view style sheet according to different view directions, and the content of the style sheet is shown in table 3. Wherein the object types include: axis, concrete beam, concrete column, girder steel, bracket, picking ear, haunching, embedded part, hole, etc.
TABLE 3 mapping style sheet Classification and header
That is, the two-dimensional legend symbol designates the corresponding color, line width, line type, etc. for the object in each three-dimensional model of the civil structure.
And 105, determining the drawing range of the target object to be drawn and the three-dimensional model of the civil structure based on the information data in the drawing platform, and acquiring intersection content of the target object and the drawing range.
In an implementation, after the information data of the generated three-dimensional model of the civil structure is imported to the drawing platform, an information list of the imported information data may be opened, for example, a pull-down list of the information data in a hierarchical relationship is opened. The information list may further include two-dimensional symbols and legend information corresponding to the object information obtained in step 104, and for example, the two-dimensional symbols may be displayed after the names of the object information, and the legend information may be displayed in the list corresponding to the object names. The engineering technician selects a target object and a drawing range of a target two-dimensional expression diagram (namely, a two-dimensional diagram in a two-dimensional drawing which is finally needed) from an information list displayed in the terminal through the operation terminal, wherein the target object is a target object to be drawn selected in the information list by a user. And then, the technician can also input coordinate information in the interface, and set a drawing range by taking the input coordinate point as a vertex, wherein the drawing range can be an area where a target object to be drawn is positioned in the civil structure three-dimensional model. The specific method for selecting the drawing range may also be as follows: opening a civil structure three-dimensional model in a drawing platform, and then selecting a proper three-dimensional space bounding box from the civil structure three-dimensional model by a user as a drawing range. The target object also comprises building structure axis information in the civil structure three-dimensional model.
After the drawing range and the target object are determined, the target object in the drawing range and the partial content of the target object in the drawing range can be obtained, and the partial content of the target object and the target object are used as intersection content. Specifically, when the drawing range is relatively large, the target object is in the drawing range, and at this time, the intersection content is the determined target object; when the drawing range is smaller, part of the target objects or part of one or more target objects is out of the drawing range, at this time, the intersection object is the part of the target object in the intersection range and one or more target objects in the drawing range, and the part of one or more target objects in the drawing range still retains the same information data as the target object corresponding to the part, so that the same-size same-type target object can be conveniently marked as the same-type object in the marking process.
And 106, determining the drawing type of the target two-dimensional expression diagram of the target content, the expression pattern of the intersection content and the drawing angle of the target two-dimensional expression diagram.
In practice, after determining the target drawing range information in step 105, a setting interface may be opened in the drawing platform to display all drawing types, and the user may select or input the drawing type of the target two-dimensional expression drawing according to the displayed drawing type, for example, set a front cross-sectional view and a cross-sectional depth, that is, a front cross-sectional view of a certain member, and a corresponding cross-sectional position at the current front (for example, 5 holes are provided in front and rear of the member at a front view angle, and a cross-section is determined at the position of the 3 rd hole). In addition, colors of different target objects and contents in intersection contents may be set at a setting interface of the objects, and an expression type of the objects in the target two-dimensional expression map, for example, a single line with a line type of 5 is used as a beam in the target two-dimensional expression map.
Specific examples are shown in Table 3:

Setting a reference angle, namely a drawing angle, of a target two-dimensional expression diagram to be drawn on the basis of coordinate axis information in axis network information at a drawing angle setting interface, wherein the drawing angle can be adjusted by rotating a compass, and related angle parameters can be input at the setting interface. For example, when the drawing angle is set to 90 degrees, when drawing a top view of the target two-dimensional expression map, the target two-dimensional expression map of the top view rotated by 90 degrees clockwise on the basis of the front top view is drawn.
The specific procedure for obtaining the drawing range of the plan view can be as follows: according to the target information data, the elevation of the position where the intersection content of the civil structure is located (namely the longitudinal height of the intersection content in the three-dimensional model of the civil structure) is obtained, the default view is a top view, the given upper and lower lateral offset of the elevation of the layer is obtained, and the drawing object in the target two-dimensional expression graph is determined according to the elevation of the structural layer and the upper and lower offset. The offset may be offset data preset in the drawing platform by an engineering technician.
The specific procedure for obtaining the drawing range of the sectional view may be as follows: the spatial cutting position of the sectional view is determined according to the axis, the view direction of the sectional view is designated, the offset of two sides of the given axis is determined, and the drawing range of the sectional view is determined according to the given axis position and the offset of two sides.
Alternatively, the specific process of determining the drawing type of the target two-dimensional expression map of the target content, the expression pattern of the intersection content, and the drawing angle of the target two-dimensional expression map may be as follows: displaying a parameter setting interface and acquiring a setting instruction of a user; specifically, a drawing type selection instruction of a target two-dimensional expression diagram is obtained, and the drawing type is determined; acquiring an expression pattern of intersection content, and determining the expression pattern; and acquiring a target axis network information selection instruction of the three-dimensional model of the civil structure, and determining a drawing angle. The target axis network information refers to information of building structure axes selected from building structure axes in a three-dimensional model of the civil structure for display in a target two-dimensional expression map; and acquiring a drawing angle setting instruction and determining a drawing angle.
In implementation, a parameter setting interface can be displayed, input operation of engineering technicians is detected, setting instructions related to the engineering technicians are obtained, selection instructions for selecting drawing types of target two-dimensional expression graphs by the engineering technicians can be obtained, and the drawing types selected by the engineering technicians are determined, for example, the engineering technicians can select sectional views or projection views and the like on the setting interface; the method comprises the steps that an instruction for selecting an expression pattern of intersection content by engineering technicians can be obtained, and the obtained expression pattern of a certain object set by the engineering technicians is determined to be the expression pattern of the object in a target two-dimensional expression diagram; the method comprises the steps that a selection instruction of engineering technicians on a building structure axis in the shaft network information of a three-dimensional model of the civil structure can be obtained, and the obtained building structure axis selected by the engineering technicians is determined to be target shaft network information required to be displayed in a target two-dimensional expression diagram; drawing angle data input by engineering technicians can be obtained, and the drawing angle can be determined based on the coordinate axes of the axis network information. Namely, in the parameter setting interface displayed on the interface, engineering technicians can select front view, side view, top view and other views, and select display modes such as projection view, cross-sectional view, semi-section view and the like; setting a specific expression mode of an object or content to be drawn, for example, setting a column in a target two-dimensional expression diagram as a line No. 3, setting a color of the column as red, and the like; selecting a portion of the building structure axis to be displayed; an angle of the selected projection or cross-sectional view in two-dimensional expression is set, for example, a top view on the right side, i.e., a top view with an angle of 90 degrees.
And 107, drawing a target two-dimensional expression diagram in a drawing platform according to a preset drawing rule according to the drawing type, the expression pattern, the two-dimensional symbol, the legend information and the drawing angle.
After the drawing type of the target two-dimensional expression diagram, the expression pattern of the intersection content and the drawing angle of the target two-dimensional expression diagram are obtained, drawing the target two-dimensional expression diagram according to the set expression pattern of the intersection content at a proper position in a drawing area displayed on a drawing platform, wherein the proper position in the area can be a coordinate origin of a drawing space defaulting.
And step 108, acquiring target annotation information corresponding to intersection content in the information data and preset annotation information of the drawing platform, and adding the target annotation information and the preset annotation information into the target two-dimensional expression graph according to a preset annotation rule.
After the two-dimensional target expression graph is drawn, marking information selected by engineering technicians in marking information such as size, name and the like corresponding to intersection content in the information data in the imported two-dimensional platform, namely target marking information, preset marking information such as all marks of preset intersection content (namely default drawing marking information in the drawing platform) is obtained in the drawing platform, and the obtained target marking information and the preset marking information are marked on the two-dimensional target expression graph according to preset marking rules. The labeling rule can be to label a lead from the center point of a line in the target two-dimensional expression diagram, and corresponding labels are added to the unit length position at one side of the line.
Specifically, the obtained target labeling information and preset labeling information of the drawing platform may include a size labeling style, an object labeling style, and related information of a frame signature column, as shown in table 4 (size labeling style), table 5 (object labeling style), and table 6 (frame and signature column style):

TABLE 5 object markup style sheet Classification and header
Table 6 frame and sign column style sheet classification and header
Optionally, the object labeling process for the target two-dimensional expression graph may specifically be as follows: the labeling rules comprise a merging principle and an overlapping principle; the merging principle comprises the following steps: if the marked object is a mergeable marked object, the marked objects with the same type and the same model are obtained from the target drawing range information based on the drawing parameters, and the marked objects are marked by the same lead; the overlapping principle includes: if the marking range of the mark is overlapped with the existing content of the drawing, detecting the content of the drawing by taking the centroid of the mark object as a pole and n times of the height of the mark word as a pole diameter; if no other content exists in the marking range, the marking is successful; wherein n is an integer greater than 0.
In implementation, the labeling rule may include a merging principle and an overlapping principle, and in the labeling process, if the types and the types of the labeled objects are the same, the labeled objects with the same types and types may be used as the mergeable labeled objects, and the same lead is used for labeling during labeling, i.e. the merging principle. If the marked range is overlapped with the content existing in the drawing, the centroid of the marked object is taken as the polar center, the content of the drawing is detected according to the clockwise or anticlockwise direction by taking n times of the height of the marked font as the polar path, and the marking is successful when no other content in the marked range is detected, namely the overlapping principle. Wherein n is an integer greater than 0.
Alternatively, when labeling is performed by adopting the merging principle, the following may be specifically mentioned: and acquiring a preset merging range, wherein the merging range is used for determining the mark objects which are the same in size and the same type in the merging range as the mergeable mark objects.
In the implementation, in the process of marking the target two-dimensional expression graph by adopting the merging principle, a merging range can be preset, namely, the merging mark objects in a certain range are led out by adopting the same lead, one mark is used for representing the merging mark objects in the merging range, the merging mark objects outside the merging range can be marked by adopting a simplified marking method, for example, the merging mark objects outside the merging mark range only mark names, models and the like, and the marks of the objects which are identical with the merging mark objects in the merging range can be determined.
The method for determining that the same mark is used for marking the mergeable mark object can be to uniformly mark the mergeable mark object in a circular range by taking the centroid of any mergeable mark object as a circle (or other geometric figures) and taking the preset length as a radius. The process of merging the ranges with the rectangle can be as follows: and uniformly marking the mergeable mark objects in the rectangular range by taking the centroid of any mergeable mark object as the centroid of the corresponding rectangle, taking the preset length as half of the diagonal line of the rectangle, and determining the rectangular range according to preset rectangular information (for example, the rectangular information is the rectangle with the hook ratio of 3:4, or the square and the like).
It is also possible to uniformly mark only the mergeable marker objects in the merging range where the mergeable marker objects are most, and to simply mark the mergeable marker objects outside the merging range.
Alternatively, the specific process of marking by using the overlay mark rule may be as follows: if other contents exist in the marking range of all the detected marks in the effective drawing range of the drawing, the effective drawing range of the drawing information is enlarged, and then the marked objects are marked.
In the implementation, in the process of marking the target two-dimensional expression graph according to the overlapping rule, if other contents exist in all detected marking ranges to be marked in the current graph, namely, the current graph does not have a position capable of being marked, the effective drawing range of the graph information can be enlarged, the marking object is marked, the effective drawing range of the graph information is enlarged, and for example, the terminal can automatically switch the paper type with the size which is one number larger than the current selected paper size to be used as the effective drawing range.
Or if other contents exist in all the detected marking ranges to be marked in the current drawing, namely, when the current drawing has no marking position, displaying an interface for setting the object, namely, an object setting interface, and through the displayed object setting interface, a user can reset the target object and the drawing range, determine a new intersection object slightly smaller than the previous intersection object, redraw the target two-dimensional expression diagram and mark the two-dimensional expression diagram.
Optionally, the labeling of the intersection content includes: axis information in the target axis network information is obtained, and axis sizes and axis numbers are marked on the left side and the lower side of the target axis network of the drawing according to the axis information; acquiring layer height information in the information data; and marking the layer height on the left side of the target two-dimensional expression graph of the graph according to the layer height information.
In the implementation, the building structure axis information and the layer height information of the whole civil structure three-dimensional model where the selected target object is located can be obtained from the target axis information, the dimension of the central axis of the target axis is marked on the left side of the building structure axis, and the axis number of the axis information is marked on the lower side; the left side of the target two-dimensional expression graph on the graph plane is marked with the layer height. When marking the layer height and the size of the target object in the intersection content, the target object in the two-dimensional expression diagram can be positioned first, the size information is marked on the left side of the target object, and the layer height information is marked on the left side of the size information of the target object.
Alternatively, the marking of the level and size in the intersection content may be performed using other marking rules that may be implemented, for example, marking the right side or the upper side of the marked object.
Alternatively, the labeling principle of the object image positioning size can be as follows: (1) preferentially adopting positioning labeling with the nearest axis; (2) If other target objects which are marked and positioned exist between the target object and the nearest axis, the positioning mark of the other similar target objects is adopted as the object mark of the target object; (3) If there is another object that has been marked and positioned between the target object and the nearest axis, marking is performed with the nearest axis within or outside the mark of the other object, for example, the target object is a column, there is another member on the column, and when the positioning size is marked, the positioning size of the column is marked outside the mark of the other member.
Alternatively, the object dimensioning principle may be as follows: (1) Objects of the same type are marked only once, and the other objects are marked only with codes. (2) The model or size of the object is expressed in the label of the object, and the object size may not be marked, for example: the label Z800x1000 represents a column with a cross-sectional dimension of 800 mm wide and 1000 mm long, which does not require labeling of the object dimensions.
The frame and the icon can be displayed according to preset contents after the labeling is completed, for example, when a target object is selected, the selection of the frame and the icon can be increased, so that the designated position (generally the position at the lower right corner) in the drawing after the labeling is completed.
Alternatively, as shown in fig. 5, the drawing process on the drawing platform may be as follows:
step 331: reading information of a three-dimensional model of the civil structure from a third-party independent database;
step 332: acquiring a setting instruction of a user, and determining a drawing range in a target two-dimensional expression diagram;
step 333: according to the determined drawing range, determining target axis network information and a target object to be drawn;
step 334: determining a drawing proportion and an expression pattern of each target object according to a setting instruction of a user;
step 335: and circularly selecting each target object of each type, and sequentially drawing according to the determined expression patterns until the drawing of the two-dimensional expression graph is completed.
Alternatively, as shown in fig. 6, the labeling process for the object in the two-dimensional representation may be as follows:
step 41: according to the target shaft network information, sequentially drawing the size label and the axis number of each axis in the target shaft network according to a rule determined by a setting instruction;
step 42: according to the layer height information, dimension marking and elevation information of each layer are set in sequence according to rules determined by the setting instruction;
step 43: sequentially setting the size labels of the target objects according to the information data of the three-dimensional model of the civil structure and the rule determined by the setting instruction;
Step 44: sequentially setting marks of the target object according to the information data of the three-dimensional model of the civil structure and rules determined by the setting instruction, and processing the merging of the marks and the overlapping problem of the marks;
step 45: drawing a picture frame and a picture label according to a rule determined by the setting instruction and according to the effective drawing range of the picture.
Alternatively, as shown in FIG. 7, the automatic labeling process using a computer program of step 108 may be as follows:
step 441: sequentially drawing information marks of various model objects according to the information data of the three-dimensional model of the civil structure and the setting of engineering technicians or programs;
s442: if the marked object is a mergeable marked object, executing S443; if no merging is required, S444 is executed;
s443: according to a merging principle set by engineering technicians or programs, guiding a plurality of objects to preset positions by using the same lead wire for unified marking;
s444: if the mark overlaps with the existing drawing content, S445 is performed; if not, executing S446;
s445: processing the label overlapping problem according to the setting principle of engineering technicians or programs to finish the object label;
s446: if all the object markers are not completed, S441 is executed; if so, the process ends.
