[0002] In the prior art, architectural design is still mainly based on two-dimensional CAD design and drawing, and the design mode of three-dimensional model drawing is gradually being explored. The two-dimensional design drawing has the disadvantages of insufficient expression of architectural details, difficulty in extracting bills of quantities, incomplete expression of complex buildings and poor visualization, which makes it difficult to meet the construction needs of Party A. As a result, the contradiction between the design results and Party A's needs is becoming increasingly prominent. The mode of design and drawing using three-dimensional models makes up for the shortcomings of the above-mentioned two-dimensional design in a very targeted manner. However, compared with two-dimensional design, the efficiency of establishing three-dimensional models is relatively low, and after the model is established and drawn, for some model modifications and drawing adjustments caused by design changes, the three-dimensional model has the problem of low modification efficiency and long time consumption. Therefore, it is urgent to adopt a design method that uses two-dimensional design to assist in improving the efficiency of three-dimensional design drawing, so as to solve the problem of low efficiency of local drawing adjustment in the three-dimensional model drawing mode, and to play a positive role in accelerating the design progress and improving the design efficiency.

[0017] Figure 1 It is a schematic diagram of a three-dimensional design drawing method assisted by two-dimensional design according to Example 1 of the present invention. DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] Example 1 Reference Figure 1 , a three-dimensional design drawing method assisted by two-dimensional design in this embodiment includes: Design 3D models based on BIM client; Convert the designed 3D model into 2D drawing; Export the converted 2D DWG format drawings and store them in the drawing area folder under the specified design area; Modify the drawings involved based on the 2D port of the CAD client; The modification of the two-dimensional drawing is updated to the three-dimensional model by using the two-dimensional and three-dimensional interlinking of the CAD client. The three-dimensional model design based on the BIM client includes directly using the BIM software to design the three-dimensional form, including the establishment of all building information models of the project. The designed three-dimensional model is converted into a two-dimensional drawing, including the conversion of the three-dimensional model to two-dimensional drawing function after the three-dimensional model is established, to obtain a two-dimensional design drawing. The two-dimensional DWG format drawing after the conversion is exported and stored in the drawing area folder under the designated design area, including finding the plan view and the large-scale view of the computer room that need to be drawn through the BIM software; through the drawing set management function, all the plan views and the large-scale views of the computer room are added and merged to establish a new independent drawing set, and the drawing set is named through the rename function; using the export drawing function, the newly created drawing set is selected, and the selected drawing set is exported as a two-dimensional DWG format drawing. The two-dimensional DWG format drawings after exporting the conversion are stored in the drawing area folder under the designated design area, and the layer corresponding settings of all the elements of the three-dimensional model are performed according to the system through the standard layer maintenance function under the standard management module; BIM export rules are set, and conversion settings are performed for each device family. The two-dimensional port based on the CAD client is used to modify the drawings involved, including using the CAD client to find the latest drawing set file, view the two-dimensional plane drawings that need to be drawn, and directly modify the design drawings in the two-dimensional CAD client port. The two-dimensional and three-dimensional interlinking of the CAD client is used to update the modifications of the two-dimensional drawings to the three-dimensional model, including calling the link CAD command under the management link function in the BIM software, linking the current two-dimensional CAD drawing into the corresponding plane view of the three-dimensional model in the form of a link, and viewing the corresponding modified content in the three-dimensional model to ensure the consistency of the three-dimensional platform and the two-dimensional platform drawings.

[0020] Specifically: a. On the 3D BIM software side, convert all plane viewports of the final model into 2D drawings. The specific operations are as follows: 1) Find all the plane views and machine room detail views that need to be drawn in the professional drawing folder through the browser under the BIM software. 2) Through the drawing set management function, add and merge all plane views and machine room detail views into a new independent drawing set, and name the drawing set through the rename function. 3) Use the export drawing function to select the newly created drawing set and export the selected drawing set into a 2D DWG format drawing.

[0021] b. The specific rules for the export drawing function are as follows: 1) The platform uses the standard layer maintenance function under the standard management module to set the corresponding layers of all the elements of the three-dimensional model according to each professional system. For example: the electromechanical water supply pipeline is a pipeline system family with three-dimensional attributes in the model. Its specific attributes include the partition system, pipeline specifications, materials, etc. When setting the corresponding layers, it is necessary to correspond the partition of this pipeline to the standard partition layer of the water supply pipeline corresponding to the two-dimensional DWG format drawing, and at the same time, the layer name and the line type of the pipeline are uniformly set to meet the drawing standards. 2) Set the BIM export rules, mainly for the conversion settings of the equipment families of various professions, including the mechanical and electrical professional computer room equipment, fire protection equipment and identification marks, etc. By setting the filtering rules of the family name and family type, corresponding to the DWG format standard layer, and setting the corresponding color and line type, finally complete the setting of the export drawing function rules.

[0022] c. The 2D DWG format drawing file system exported from the drawing set will be stored in the drawing area folder under the specific design area, and the 2D drawing file will be named with the name of the drawing set by default. This function is of great significance to the project progress management and project drawing document management, and can store and archive important node documents in a designated area in a timely manner.

[0023] d. After completing the above work, open the CAD platform, enter the project and find the drawing area folder under the design area of ​​this project, open the latest drawing set file, and you can view all the 2D plane drawings that need to be drawn. At this time, all 3D model contents are converted into 2D drawing formats under the standard mode, and the layers, line types, colors and annotation styles of each professional system meet the drawing standard requirements. At this time, if there is a change in the drawing, you need to enter the 3D model again to modify it, and then repeat the above operations to complete the drawing of the 2D drawing. This will greatly extend the time for design change and drawing modification, affecting the progress of project construction.

[0024] e. To address this problem, you can directly modify the 2D drawings from the 2D CAD end, and then export the drawings after the modification is completed, eliminating the tedious arrangement from 3D model modification to 2D drawing export. After the 2D drawings are modified, use the 2D and 3D interlinking function of the platform and select the operation of updating the 2D drawings to the 3D model. The modified 2D drawings can be updated to the 3D model to complete the direction modification operation.

[0025] f. The specific steps for updating the 2D drawings to the 3D model are as follows: 1) The 2D drawings that need to be updated must be drawings in the drawing area exported from the 3D drawings. Drawings in other areas cannot be linked to each other. 2) The linking function is to call the link CAD command under the management link function in the BIM software to link the current 2D CAD drawing to the corresponding plane view of the 3D model in the form of a link. The corresponding modified content can be viewed in the 3D model, ensuring the consistency of the 3D platform and the 2D platform drawings.

[0026] g. The web page can also synchronize and update the drawing content, further realizing the efficient two-dimensional assistance to improve the three-dimensional design. The specific operations are as follows: 1) Log in to the web page platform with the same account, enter the project management work interface, and the updated drawings can be displayed in the drawing folder under the design area of ​​this project. 2) In addition to the viewing function on the web page, the version comparison function can also be realized. Select the version comparison option, and you can select the version drawings to be compared in the pop-up window for comparison. The comparison results are directly displayed in the web page interface, and different colors are used to distinguish the newly added, overlapped and deleted content of this modification, which is convenient for designers to quickly view. 3) Layer management can also realize the display and closing of specific layers on the web page for easy viewing. 4) The designer can quickly view through the mobile phone, which is a significant advantage of the web page synchronization drawings.

[0027] 3D model design further improves the visualization of design drawings and provides more professional and comprehensive technical support for project management. In the pursuit and exploration of more efficient 3D design, it is inevitable to encounter a situation where the design time is short and the content is modified a lot. 2D auxiliary design can also play a vital role in the whole process. Under the premise of meeting the drawing requirements, it can be reversely updated to the plane view corresponding to the 3D model at the same time, which has a significant effect in improving design efficiency.

[0028] According to the method described in claim 1, it is characterized in that the three-dimensional design does not adopt the traditional two-dimensional CAD design mode in the design stage, but directly adopts BIM software to carry out three-dimensional design, including the establishment of all building information models of the project. After the establishment is completed, the three-dimensional model is converted into a two-dimensional drawing function to achieve the simultaneous delivery of the three-dimensional model and the two-dimensional drawing to the client and the construction party, providing more professional technical support for project management and construction management.

[0029] The two-dimensional design according to claim 1 is characterized in that the two-dimensional drawings converted from the three-dimensional model are changed and refined through the two-dimensional CAD software, and the connection between the two-dimensional and three-dimensional projects is mainly carried out through the collaborative platform. The two-dimensional design mainly plays a supplementary and modifying role for the three-dimensional design, aiming to improve the design efficiency, and can be reversely updated to the three-dimensional model at the same time.
