Fig. 1 is an optional flowchart of an architectural design drawing importing method provided in an embodiment of the present disclosure, where the method in fig. 1 may include, but is not limited to, steps S110 to S180, and specifically includes:
s110, acquiring a two-dimensional drawing file of the architectural design;
s120, carrying out format unified processing on the architectural design two-dimensional drawing file to obtain architectural design two-dimensional drawing information;
s130, obtaining packaging characteristic information of the initial building information model;
s140, identifying drawing type information in the two-dimensional drawing information of the architectural design, and performing layer analysis processing according to the drawing type information and the component layer characteristic information to obtain layer information corresponding to the drawing type information;
s150, performing line reading processing on the two-dimensional architectural design drawing information according to the layer information to obtain a target line;
s160, carrying out line relation analysis on the target line according to the component specification characteristic information and preset simulated manual image reading rule information to obtain line combination relation information, and carrying out association processing on the target line according to the line combination relation information to obtain a component section;
s170, generating a target component according to the component segment;
and S180, importing the target component into the initial building information model according to the component association feature information to obtain a target building information model.
In step S110, the two-dimensional architectural design drawing file is a two-dimensional electronic drawing file to be read, such as a drawing file in dwg format.
In step S120, information such as image blocks, line segments, arcs, multi-segment lines, ambiguous lines, padding, single-row characters, multi-row characters, labels, and the like in the drawing is read from the two-dimensional drawing file of the architectural design, and the information is processed in a unified format, for example, the information is converted into two-dimensional drawing information of the architectural design such as line segments, arcs, characters, and the like, and the information is processed according to the identification requirement, so as to improve the identification efficiency of the subsequent identification process, simplify the identification process, and unify the formats of the two-dimensional drawings of different sources.
In step S130, an initial building information model is first obtained, where the initial building information model is a model already created in the BIM, then, component feature analysis is performed on the created BIM model, so as to obtain all features included in different types of components, and finally, component attribute encapsulation processing needs to be performed on the component feature information, so as to encapsulate the component feature information into limited important features, that is, encapsulation feature information. Specifically, the package feature information at least includes component layer feature information, component specification feature information, and component association feature information.
The component layer feature information represents a corresponding relationship between drawing type information and layer information, and is used in the layer analysis processing process in step S140; the component specification characteristic information represents a specification data index of the component, and is used in the line relation analysis process in the step S160; the component-related feature information characterizes a relationship between the target component and the built model component, and is used in the component importing process of step S180, and is also used in the support relationship analysis processing process of step S410 and the chamfer relationship analysis processing process of step S510.
In step S140, obtaining layer information according to drawing type information in the two-dimensional drawing information of the architectural design to be identified, if the drawing belongs to a floor plan type; the component layer feature information contains the layer name of each drawing type information, so that the required layer can be screened out according to the drawing type and the component layer feature information, and the required layer is the layer where the information such as lines and the like required by the identification component is located.
Specifically, in order to realize passing through the feature recognition means, it is necessary to complete recognition of the drawing type information, and the drawing type information of the drawing is analyzed first to confirm the type of the drawing. For example, the drawing is a wall column positioning drawing, and the drawing mainly relates to a concrete wall, a hidden column and a connecting beam, so that the characteristics of the drawing are analyzed in the analysis process according to the modes of the concrete wall, the hidden column and the connecting beam, and the relevant line drawing layer of the corresponding component is obtained; for another example, when the drawing type information is a floor table type, the position and lines of the floor table are analyzed through character features in the floor table, and corresponding floor table data are analyzed from a large number of drawings.
In step S150, a line reading process is performed from the drawing according to the layer information obtained in step S140, so as to obtain a target line, where the target line is a line to be identified.
In step S160, the component specification characteristic information is a specification data index of the component, for example, the width design requirement of the concrete wall is generally between 200mm and 600mm, and a certain modulus requirement is satisfied; the simulated manual drawing rule information is a drawing rule simulated according to the steps of looking at the picture by a professional, and is used for line relation analysis, for example, in a concrete wall, if two parallel lines are found within a certain width, whether the two lines can be combined into a section of the concrete wall is judged according to the width design requirement of the concrete wall; if 4 parallel lines are found and the distances between the 4 lines are relatively close, whether the parallel lines can be combined into 2 sections of parallel concrete walls needs to be judged. And after obtaining the line combination relation information, combining the found associated lines into the component segments needing to be identified.
The building design drawing importing method provided by the embodiment of the disclosure improves the accuracy of drawing identification through an intelligent analysis method, adopts a mode of simulating professional reading in the drawing identification process, analyzes relevant information in the design drawing, analyzes correct information in complex design drawing information, then processes the drawing information by utilizing the information in the drawings, reads the drawing content according to lines and characters, and analyzes the lines and the characters through analysis, thereby identifying components in the drawings.
In step S170, the lines may be segmented, so that the building segments are segmented, and after the lines are combined to form the building segments, the building segments are combined to obtain the members, before that, the members need to be analyzed, and the scattered member segments are combined into specific members according to professional judgment of the distance between the ends. For example, when the middle of the design line is broken, the components need to be combined with each other.
And after the components are combined into a component, obtaining a first target sub-component, then performing overlap removal processing on the first target sub-component to obtain a second target sub-component, and finally performing label analysis processing on the second target sub-component to obtain the target component.
In step S180, the component-related feature information includes a relationship between the obtained target component and a model component already built in the initial building information model, and the target component is imported according to the relationship to obtain a target building information model, i.e., an imported BIM model.
It should be noted that, the method for importing the architectural design drawing provided in the embodiment of the present disclosure may also determine whether the identified component is accurate by analyzing the support components of different drawings, and specifically includes: and comparing the same type of components identified by different drawings with the same type of components in the existing model so as to ensure the accuracy of component identification.
The architectural design drawing importing method and device, the electronic device and the storage medium provided by the embodiment of the disclosure firstly acquire an architectural design two-dimensional drawing file, and carry out format unified processing to obtain architectural design two-dimensional drawing information, then obtaining the packaging characteristic information of the initial building information model, then identifying the drawing type information in the two-dimensional drawing information of the building design, and obtaining the layer information according to the drawing type information, further obtaining a target line according to the layer information, then obtaining line combination relation information according to the component specification characteristic information and the preset simulated manual image reading rule information, and performing association processing on the target line according to the line combination relation information to obtain a component section, and finally generating a target component and importing the target component.
In some embodiments, obtaining package feature information of the initial building information model comprises: acquiring an initial building information model; carrying out component characteristic analysis processing on the initial building information model to obtain component characteristic information; and performing component attribute packaging processing on the component characteristic information to obtain packaging characteristic information.
Fig. 2 is a flow chart of step S130 in some embodiments, and step S130 illustrated in fig. 2 includes, but is not limited to, step S210 to step S230:
s210, acquiring an initial building information model;
s220, performing component characteristic analysis processing on the initial building information model to obtain component characteristic information;
and S230, performing component attribute packaging processing on the component characteristic information to obtain packaging characteristic information.
In step S210, the initial building information model is the model already created in the BIM, containing all components that have been added to the model.
In step S220, by performing component feature analysis on the created BIM model, all features included in different types of components can be obtained for the identification process of the components in the two-dimensional drawing.
Specifically, from the initial building information model, component feature information of the component is read, including but not limited to: a support for a component, a component associated with a component to be identified. For example, when a beam is identified, members such as a column, a hidden column, a concrete wall, and a beam need to be used as member characteristic information.
In step S230, there is a lot of component feature information in step S220, but if these features are considered on a full scale, the efficiency of component identification is reduced, so that it is necessary to perform component attribute encapsulation processing on the component feature information to encapsulate the component feature information as limited important features, i.e., encapsulation feature information.
Specifically, from the initial building information model, the component feature information is accessed through the interface, and the read components are packaged, wherein the packaged information includes but is not limited to: the data of curves, component numbers, component elevations, component widths and the like corresponding to each component are reserved, and the data are used for improving the identification efficiency of the components and simplifying an identification algorithm.
In a specific embodiment, the component characteristic information is encapsulated, so that the dependence on a model platform can be separated in a specific identification algorithm, and meanwhile, the extracted encapsulation characteristic information only concerns the information required by identification, so that interference information items are isolated, and the identification efficiency is improved. For example, there may be 50 attributes (corresponding to the component feature information) on the column component, but only 5 of them (corresponding to the package feature information) are required for identification; for another example, when a beam is identified, members such as a foundation and the like do not need to be considered, so that the identification efficiency can be improved.
In some embodiments, generating a target component from a component segment includes: combining the component sections to obtain a first target sub-component; performing de-overlapping processing on the first target sub-component to obtain a second target sub-component; and performing label analysis processing on the second target sub-component to obtain the target component.
Fig. 3 is a flow chart of step S170 in some embodiments, and step S170 illustrated in fig. 3 includes, but is not limited to, step S310 to step S330:
s310, carrying out combined processing on the component sections to obtain a first target sub-component;
s320, performing overlap removal processing on the first target sub-component to obtain a second target sub-component;
and S330, performing label analysis processing on the second target sub-component to obtain the target component.
In step S310, the lines may be segmented, so the building segments are segmented, and after the lines are combined to form the building segments, the building segments are combined to obtain the components, before that, the components need to be analyzed, and the scattered component segments are combined into specific components according to professional judgment of the distance between the ends. For example, when the middle of the design line is broken, the components need to be combined with each other.
In step S320, the component lines of the identification process and the component feature information read from the model are used to search for the components of the accessory, determine whether there is an overlap between the components, and if so, perform the de-overlap process, wherein the component feature information includes component related feature information including the identified positional relationship of the components.
Specifically, the member of the concrete wall accessory is searched through the starting point, the ending point and the wall height of the concrete wall, then whether part of the member is completely overlapped with the support is judged, if the line of the concrete wall is completely in the column, the analyzed concrete wall is possibly completely in the column, and in this case, the part of the concrete wall needs to be deleted.
In step S330, the annotation analysis process includes: and analyzing the marking mode characteristics of the component type in the drawing according to the analyzed and processed component type, and finding out the corresponding mark of the component, wherein the marking information comprises the serial number, the section size, the mark and the like of the component. Different components are labeled in different ways, and labeled contents are different. For example: generally, only the serial number of the concrete wall is marked on the concrete wall, the serial number information in the design drawing is assigned to the associated concrete wall, the upper and lower association relation of the concrete wall is analyzed, and the serial number assignment is carried out on the peripheral concrete wall.
In some embodiments, the method further comprises: carrying out support relation analysis processing on the target building information model according to the member correlation characteristic information to obtain a support member; the tip or bottom of the target member is extended to the abutment member.

s410, carrying out support relation analysis processing on the target building information model according to the member association characteristic information to obtain a support member;
and S420, extending the end head or the bottom of the target component to the support component.
In step S410, the target member and the existing members in the model are analyzed to determine whether or not the members have a bearing relationship, and the member having the bearing relationship with the target member is a bearing member.
In step S420, if the support member exists in the model, the end or the bottom of the target member is extended to the edge of the support member, thereby completing the BIM model.
In some embodiments, the method further comprises: performing chamfering relation analysis processing on the target building information model according to the member correlation characteristic information to obtain a member to be chamfered; and chamfering the target member and the member to be chamfered.
As shown in fig. 5, fig. 5 is a second flowchart of an architectural design drawing importing method according to another embodiment, where the architectural design drawing importing method further includes:
s510, carrying out chamfering relation analysis processing on the target building information model according to the member association characteristic information to obtain a member to be chamfered;
and S520, chamfering the target member and the member to be chamfered.
In step S510, chamfer relation analysis processing is performed on the analyzed target member and members already existing in the model, and it is determined whether chamfering should be performed between the members, and the member having a chamfer relation with the target member is a member to be chamfered.
In step S520, if the members are chamfered, the horizontal members (concrete wall, masonry wall, beam) with their ends contacting each other are extended to the edge of the member in the model, and the target member and the member to be chamfered are chamfered, thereby completing the BIM model.
In some embodiments, the method further comprises: carrying out combined component identification processing on the target building information model to obtain a target combined component; the target combination member includes at least any one of: beam members, bar base members; sequencing the target combined components to obtain sequencing information; and importing the sequencing information into the target building information model.

and S630, importing the sequencing information into the target building information model.
In step S610, the target combination component is a component that can be labeled in groups, and the target combination component includes at least any one of the following: beam member, strip base member.
In steps S620 to S630, the identified target combined members are grouped according to the span data in the corresponding numbers, the grouped members correspond to the same group number value, and are sorted from left to right and from top to bottom to obtain sorting information, and a target building information model is imported for generating members in the BIM model, so as to group, label and sort the target combined members, thereby facilitating the operations of searching, querying, adding and deleting, managing and the like of the members of the type, and improving the modeling efficiency of the model.
In some embodiments, the method further comprises: saving the architectural design two-dimensional drawing file as original component data information; and importing the original component data information into the target building information model.
As shown in fig. 7, fig. 7 is a fourth flowchart of an architectural design drawing importing method according to another embodiment, where the architectural design drawing importing method further includes:
s710, storing the two-dimensional architectural design drawing file as original component data information;
and S720, importing the original component data information into the target building information model.
