Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, as shown in fig. 1, a drawing generation method is provided, and this embodiment is illustrated by applying the method to a terminal, and it is to be understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:
s102: and acquiring an initial three-dimensional model of the drawing to be generated.
Specifically, the initial three-dimensional model refers to a pre-established BIM model, such as a building model established in Revit, and the like, wherein the initial three-dimensional model may include at least one member, and each member includes a position, a size, a structure, constraints, and the like of the member.
The obtaining of the initial three-dimensional model of the drawing to be generated may be opening a file corresponding to the initial three-dimensional model in Revit, or directly creating the initial three-dimensional model in Revit.
S104: and receiving a model range selection instruction, and determining a model range according to the model range selection instruction.
Specifically, the model range selection instruction may be an instruction for a user to select a frame in the initial three-dimensional model by using a mouse or the like, and may be used to select some or all components in the initial three-dimensional model, where the user may select a model range in which a drawing needs to be generated as needed.
The model range refers to a range of the drawing to be generated, for example, an initial three-dimensional model in a selection box corresponding to the model range selection instruction is the model range.
In one embodiment, the terminal is provided with a plug-in developed secondarily through RevitAPI, and the plug-in can select a component corresponding to an initial three-dimensional model in a model range framed by a model range selection instruction and extract a corresponding component parameter after the terminal receives the model range selection instruction.
Specifically, in the above embodiment, in the step of selecting the model range, the components in the selected model range may be filtered (Filtering) according to the model range selection instruction input by the user through a pre-developed function, for example, the terminal acquires the selection frame corresponding to the model range selection instruction, and then determines the position of the selection frame in the initial three-dimensional model, so as to compare the coordinate range of the selection frame and the coordinates of the position of the component, so as to determine the component whose position is within the coordinate range, thereby completing the selection of the component. The coordinate comparison comprises the coordinate comparison of the position of the component, namely the position of a source point (Origin), and if the central position of the component is located in the coordinate range of the selection frame, the component is determined to be the selected component.
S106: component parameters of each component within the model are read.
Specifically, the terminal reads the components within the model, for example, reads the unique identification of the component, i.e., the component ID, and then obtains the corresponding component parameters according to the ID of the component.
The component parameters include the position, size, structure, and constraints of the component, and if the component requires a solid body, such as a rebar, the component parameters also include a textual description of the solid body. The establishment of a building block in Revit is reflected in the increase of overall data, namely building block parameters. For example, the origin coordinates (X, Y, Z) of the component, the dimensions of the component (length X width X height), the elevation at which the component is located, and so on.
S108: and calling the component parameters to generate a target drawing.
Specifically, after the terminal generates the initial three-dimensional model, each component parameter is obtained according to the selected model range, so that a drawing is generated according to the component parameters, and the drawing comprises a large amount of information, so that the quality of the drawing is improved.
In one embodiment, the manner of generating the drawing can include visualization drawing and parameterization drawing. The visualized drawing refers to that after a two-dimensional drawing is generated according to component parameters, the two-dimensional drawing is annotated according to the component parameters, such as a text annotation (TextNote), a Dimension annotation (Dimension), an independent mark (IndependentTag), an annotation symbol (annotation symbol), and the like. The parameterized drawing is classified and generalized according to the component parameters, and then the target drawing meeting the requirements is generated. Therefore, optionally, when the target drawing is generated, the terminal may determine whether to perform visualization drawing or parameterization drawing according to the drawing mode selected by the user, and then generate the target drawing according to the drawing logic corresponding to the corresponding drawing mode.
In one embodiment, it should be noted that the reading of the component parameters may be a function developed by Visual C #, that is, the Visual C # obtains data in the Revit model through RevitAPI, and then processes the read component parameters through Matlab, because the capability of processing data of the Visual C # is much smaller than that of Matlab, Matlab is used to sort the data, so that the efficiency of data obtaining and the efficiency of processing can be ensured. The step of processing the read component parameters by Matlab, that is, generating the target drawing, may specifically refer to the specific description of the visual chart and the parametric chart in the foregoing.
According to the drawing generation method, after the initial three-dimensional model is obtained, the selected model range and the required components are filtered, and the drawing is generated according to parameters of each component in the initial three-dimensional model, so that the drawing quality is improved, and the intelligent level of drawing generation is improved.
In one embodiment, invoking component parameters to generate a target drawing comprises: acquiring a current projection surface corresponding to a current view; generating a two-dimensional drawing according to the model range and the projection plane; and annotating on the two-dimensional drawing according to the acquired component parameters to obtain a target drawing.
Specifically, the current projection plane includes a plane, a vertical plane, or a cross section, specifically, a plane, a vertical plane, or a cross section corresponding to a viewing angle of a view currently displayed by Revit, that is, if a certain part in the model needs to be expressed, the current projection plane is obtained by directly projecting in the model.
In this embodiment, the terminal acquires the two-dimensional cross section corresponding to each component according to the current plane, facade or section, so as to generate a two-dimensional drawing according to the two-dimensional cross section of each component in the model range, and then annotate according to the component parameters in the two-dimensional drawing. The generation mode of the two-dimensional drawing can be calling the function of the original visual graph in Revit, and the automatic annotation is calling the function after secondary development for annotation.
The annotation is an automatic annotation, for example, the terminal may add or directly obtain a reference surface (refer) along a side line of each component or a centerline of the component in the two-dimensional drawing, and then perform size labeling according to the component parameters and the reference surface; and adding text comments, independent marks, comment symbols and the like to the corresponding positions of the two-dimensional drawing according to the text description in the component parameters. The calculation principle is as follows: the method comprises the steps of obtaining source point coordinates and size information of a component, calculating to obtain boundary information of the component, creating or obtaining reference surfaces at corresponding positions, attaching the reference surfaces to reference surface sets (refereenearray) one by one, carrying out size marking according to View positions (View) and marking styles (DimensionType), outputting the condition that the number of the reference surface sets is more than or equal to 2, obtaining the source point coordinates and the size information of the component, and obtaining annotation coordinates according to a drawing standard to generate the corresponding positions.
Specifically, referring to fig. 2, fig. 2 is a simplified diagram of a target drawing obtained by visualizing a drawing in one embodiment, in which annotation information is given.
In the embodiment, the secondary development is performed by combining the visual plotting scheme of the original Revit to call the component parameters to obtain the annotation information in the two-dimensional drawing, and then the annotation is performed to the corresponding position of the two-dimensional drawing, so that the data in the generated drawing is complete, and the quality of the drawing is improved.
In one embodiment, invoking component parameters to generate a target drawing comprises: classifying the component according to the component parameter; counting the number of components in each classification; generating a unified parameter description for the components in each classification according to the component parameters; and generating a component parameter table according to the parameter description and the quantity of the components.
Specifically, in this embodiment, a parameterized graph is mainly introduced, wherein after a user selects a model range, components in the model range are classified, for example, the components are classified according to component types and component sizes in component parameters, a terminal may classify the components according to the component types, for example, the components are classified into doors, windows, and the like, then the components in each class are classified according to the component sizes, for example, the class of doors, and the class of the components are classified according to the component sizes, so that the components are divided into a plurality of subclasses, so that the terminal counts the number of the components in each subclass, then a unified parameter description, for example, the size, name, and the like of the component, is generated according to the parameter description and the number of the components, so that a graph is obtained, which can be generated as needed, and accurately describes data required by the user, the drawing quality is high.
Specifically, as shown in fig. 3, fig. 3 is a simplified diagram of a target drawing of a parametric drawing in an embodiment, in which members are divided into doors and windows, the doors are divided into a plurality of types of doors, and the size, name, and the like of each type of door are given.
In one embodiment, fields related to unified parameter descriptions in the component parameter table may be predefined by a user, and when the terminal generates the component parameter table, the terminal may determine corresponding fields according to the unified parameter descriptions preset by the user, and then obtain corresponding field values from the component parameters according to field obtaining logic, for example, directly obtain or obtain the corresponding field values by calculation according to the component parameters. In addition, the types of the components and the like in the component parameter table may be predefined by the user, so that the components of the corresponding types are acquired according to the component parameter table, and the required data is acquired.
In the above embodiment, the required drawing is directly obtained, and no post-processing, i.e., what is required and what is generated, is required.
In one embodiment, specifically, referring to fig. 4, fig. 4 is a flowchart of a generation manner of an initial three-dimensional model in an embodiment, where the generation manner of the initial three-dimensional model includes:
s402: and receiving a component type selection instruction, and calling a component parameter input interface according to the component type selection instruction.
Specifically, the component type selection instruction may be a selection instruction in a drop-down box of a component type provided in a software interface, the component parameter input interface is an interface for acquiring a component parameter input by a user, a model parameter input interface is provided in this embodiment, the terminal first receives the selected component type, and then displays the component parameter input interface, and a field of the component parameter corresponding to the component type is displayed in the interface, so that the user may input a parameter value after the corresponding field.
S404: and receiving the input component parameters through the component parameter input interface.
The component parameters include the position, size, structure, and constraints of the component, and if the component requires a solid body, such as a rebar, the component parameters also include a textual description of the solid body. The establishment of a building block in Revit is reflected in the increase of overall data, namely building block parameters. For example, the origin coordinates (X, Y, Z) of the component, the dimensions of the component (length X width X height), the elevation at which the component is located, and so on.
The terminal may generate the component from the component parameters by calling an existing component generation function. Specifically, the process of generating is a process of generating a three-dimensional model from parameters of the component. An initial three-dimensional model may include at least one component to complete modeling, i.e., data corresponding to a large scale is stored, and then a program is written to obtain the data for processing.
The user can input the parameter value after the corresponding field, so that the terminal can acquire the parameter value input by the user.
S406: and selecting a corresponding basic template according to the type of the component, processing the basic model through the component parameters to obtain the component, and determining the position of the component according to the position information of the component parameters to generate an initial three-dimensional model.
Specifically, the basic template is a three-dimensional template corresponding to the component, and the size of the basic template may be a default, so that the terminal receives relevant parameters, such as a position coordinate, a size, a bottom elevation, a top elevation and the like of the component, input by a user, where optionally, if the units of the parameters are not uniform, the terminal preferentially unifies the units, then adjusts the basic model according to the parameter values of the unified units to obtain the component, and processes the multiple components to obtain the initial three-dimensional model.
In the embodiment, the component is generated according to the input component parameters, and the component is not drawn manually by a user, so that the intelligent level and the three-dimensional visualization effect are improved.
In one embodiment, after obtaining the initial three-dimensional model of the drawing to be generated, the method further includes: acquiring a component to be processed in the initial three-dimensional model, and extracting initial model data corresponding to the component to be processed; and processing the initial model data to obtain entity information, and adding the generated entity information to the initial three-dimensional model to obtain a target three-dimensional model.
Specifically, the component to be processed may be a component in which entity information needs to be generated, for example, a component in which a textual description of a reinforcing bar exists, or a component in which a textual description of other entity information exists. The model data may refer to a portion of the component parameters, and in one embodiment, the model data may refer to the component parameters of the selected component to be processed.
The terminal can receive a selection instruction of the to-be-processed member input by the user, so that the to-be-processed member is selected, and after the to-be-processed member is determined, the terminal extracts model data corresponding to the to-be-processed member, wherein the model data comprises a text description of an entity, such as a text description of a steel bar.
Specifically, the entity information is information for converting the model data into a three-dimensional displayed model, for example, text description of a steel bar is converted into information of the steel bar of the entity, so that the target three-dimensional model can be obtained by adding the information of the steel bar of the entity obtained by conversion into the initial three-dimensional model, and the target three-dimensional model includes abundant data, so that data of a drawing generated according to the target three-dimensional model in the following process is also abundant.
Optionally, the extracting the model data corresponding to the member to be processed includes: and extracting initial model data from the initial three-dimensional model by calling a model data acquisition function developed by Visual C #.

Further, processing the model data to obtain entity information, including: and generating an entity position according to the position information and the size information of the member to be processed in the model data, and obtaining entity information according to the type of the selected entity and the entity position.
Specifically, the terminal may first obtain the position information and the size information of the member to be processed, so that the spatial position coordinates of the entity, for example, the spatial position coordinates of the reinforcing steel bar, may determine the model line according to the control position coordinates, and then convert the model line into the required longitudinal reinforcing steel bar, hoop reinforcement, and the like according to the selected type of the entity, for example, the type of the reinforcing steel bar and the type of the hook, thereby implementing the generation of the entity information.
Therefore, calling component parameters to generate a target drawing, comprising: acquiring entity information corresponding to a model range in a target three-dimensional model; and displaying the component parameters and the entity information through a three-dimensional visualization effect.
Specifically, the terminal can obtain each component parameter and entity information in the target three-dimensional model by calling a drawing generation function developed by Visual C #, and display the component parameters and the entity information through a three-dimensional visualization effect. In this embodiment, the Visual C # is called to obtain data in the Revit model through revitappi, so that rapid data reading can be realized, and then the read data is displayed according to a preset visualization effect, so as to realize a three-dimensional visualization effect.
In one embodiment, the drawing generation method may further include: extracting target model data from the target three-dimensional model; acquiring a calculation amount generation template; and processing the target model data according to the calculated amount generation template to obtain the corresponding material calculated amount.
Specifically, the target model data is data of a material, such as a steel bar, for which a material calculation amount needs to be calculated, and therefore, in this embodiment, the target model data may be acquired first, for example, the target model data is extracted by using C #, then the model data is processed to obtain the material calculation amount, for example, the model data is processed by using matlab, and then the final material calculation amount is output, for example, the final material calculation amount is output by using C #.
For clarity of explanation, the calculated amount of the steel bar is taken as an example in the present embodiment, and in other embodiments, the calculated amount of other materials or the calculated amount of engineering (including the calculated amount of all materials) may also be used.
