[0039] To make the purpose, technical scheme and effects of the present application clearer and more explicit, the present application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0040] The embodiment provides a BIM-based graphic primitive single-item withdrawal method. Based on the method of the embodiment, graphic primitives can be withdrawn in a single item, and the use of users is facilitated. Specifically, the embodiment first receives a withdrawal operation instruction and records withdrawal time information corresponding to the withdrawal operation instruction. Then, according to the withdrawal operation instruction, a target graphic primitive corresponding to the withdrawal operation instruction is determined, and the target graphic primitive is a graphic primitive in BIM software. Finally, according to the target graphic primitive and the withdrawal time information, target timestamp information corresponding to the target graphic primitive after the target graphic primitive executes the withdrawal operation instruction according to the withdrawal time information is determined, and current parameter information of the target graphic primitive is modified to target parameter information corresponding to the target timestamp information. The embodiment can directly locate corresponding target timestamp information based on withdrawal time information corresponding to the withdrawal operation instruction, and then modify current parameter information of the target graphic primitive to target parameter information corresponding to the target timestamp information, so as to complete graphic primitive single-item withdrawal, which is convenient to operate and is beneficial to realize accurate withdrawal and improve work efficiency. In addition, the present application deletes the steps corresponding to the parameter changes between the current parameter information and the target parameter information. Users can still locate corresponding parameter information based on timestamp information to modify the current parameters of the target graphic primitive, so as to realize single-item withdrawal of the target graphic primitive, without affecting the use of users.

[0041] For example, a terminal device (such as a computer) records timestamp information and parameter information corresponding to the timestamp information for each modification of a user to a graphic primitive A, for example, parameter B is added to the graphic primitive A at 10:24:20 on June 10, 2022. When the user needs to perform a withdrawal operation on the graphic primitive A, the terminal device receives a withdrawal operation instruction and records withdrawal time information corresponding to the withdrawal operation instruction at this time. Then, the timestamp information obtained after the graphic primitive A is withdrawn according to the withdrawal time information is determined, for example, the obtained timestamp information is 10:24:20 on June 10, 2022. At this time, the current parameters of the graphic primitive A can be directly replaced with the parameter information corresponding to 10:24:20 on June 10, 2022, so that the withdrawal operation on the graphic primitive A can be completed. The entire withdrawal operation does not affect other graphic primitives, and the withdrawal process is accurate in time, and the steps are not permanently deleted. These steps can also be obtained based on the timestamp method, which facilitates the use of users.

[0042] Exemplary method

[0043] The BIM-based graphic primitive single-item withdrawal method of the embodiment can be applied to a terminal device, which can be a computer, a mobile phone or other intelligent terminal products. In the embodiment, as shown in Figure 1 The BIM-based graphic primitive single-item withdrawal method includes the following steps:

[0044] Step S100, receiving a withdrawal operation instruction, and recording withdrawal times information corresponding to the withdrawal operation instruction.

[0045] When a user needs to perform a withdrawal operation on a certain graphic element in a BIM software, the terminal device receives a withdrawal operation instruction, which is used to control the body graphic element to return to a certain previous state. After receiving the withdrawal operation instruction, the terminal device of the embodiment starts to record the withdrawal times information corresponding to the withdrawal operation instruction. The withdrawal times information in the embodiment indicates how many times the user needs to perform a withdrawal on the graphic element, that is, which previous state the user wants to control the graphic element to return to.

[0046] In an implementation manner, the embodiment in determining the withdrawal times information includes the following steps:

[0047] Step S101, when receiving the withdrawal operation instruction, determining an operation key corresponding to the withdrawal operation instruction;

[0048] Step S102, recording the number of times the operation key is continuously operated, and taking the number of times the operation key is continuously operated as the withdrawal times information corresponding to the withdrawal operation instruction.

[0049] Specifically, after receiving the withdrawal operation instruction, the terminal device of the embodiment analyzes the withdrawal operation instruction. Since the withdrawal operation instruction is issued based on the operation key on the terminal device, for example, the user can issue the withdrawal operation instruction through the Ctrl+Z operation key on the computer. Therefore, the terminal device can record the number of times the operation key is continuously operated, and the number of times the operation key is continuously operated is the withdrawal times information corresponding to the withdrawal operation instruction. For example, when the computer obtains that the user continuously presses the Ctrl+Z operation key three times, it can be determined that the withdrawal times information of the withdrawal operation instruction issued by the Ctrl+Z operation key is three times.

[0050] In an implementation manner, when the first Ctrl+Z operation key is operated, the first time is recorded, and then the second Ctrl+Z operation key is operated, and the second time is also recorded. If the interval between the first time and the second time is short (for example, less than 1 second), it can be determined that the operation of pressing the first Ctrl+Z operation key and the operation of pressing the second Ctrl+Z operation key are continuous operations. Based on this, all continuous operations of pressing the Ctrl+Z operation key are recorded, and then the number of times of continuously pressing the Ctrl+Z operation key is recorded.

[0051] Step S200, determining a target graph element corresponding to the withdrawal operation instruction according to the withdrawal operation instruction, the target graph element being a graph element in the BIM software.

[0052] After receiving the withdrawal operation instruction, the embodiment needs to determine the target graph element corresponding to the withdrawal operation instruction, that is, which graph element the user wants to perform the withdrawal operation on. Since there are many graph elements in the BIM software, and the user wants to perform the withdrawal operation on a certain graph element in the BIM software by issuing the withdrawal operation instruction, in order to avoid affecting other graph elements, the embodiment needs to determine the target graph element according to the withdrawal operation instruction.

[0053] In one implementation manner, when determining the target graph element, the embodiment includes the following steps:

[0054] Step S201, analyzing the withdrawal operation instruction to determine a graph element ID corresponding to the withdrawal operation instruction;

[0055] Step S202, determining the target graph element corresponding to the graph element ID according to the graph element ID.

[0056] Specifically, the embodiment can analyze the withdrawal operation instruction to obtain the graph element ID in the withdrawal operation, the graph element ID can be used to identify the graph element, that is, each graph element has a unique graph element ID, and the withdrawal operation instruction is targeted, that is, the withdrawal operation instruction is processed for a certain graph element, so the withdrawal operation instruction has the graph element ID of the graph element to be processed. After obtaining the graph element ID, the embodiment can determine the target graph element corresponding to the graph element ID.

[0057] In another implementation manner, when determining the target graph element, the embodiment can further include the following steps:

[0058] Step S21, determining a cursor corresponding to the withdrawal operation instruction and position information corresponding to the cursor according to the withdrawal operation instruction;

[0059] Step S22, if the position information of the cursor is located on a graph element of the BIM software, taking the graph element corresponding to the position information of the cursor as the target graph element.

[0060] The withdrawal operation instruction in the embodiment is for operating the primitives in the BIM software, and the withdrawal operation instruction is presented on the screen of the terminal device in the form of a cursor. When the cursor corresponding to the withdrawal operation instruction is located on a certain primitive on the BIM software, it means that the withdrawal operation is needed for the primitive at this time. Therefore, the embodiment can determine the cursor corresponding to the withdrawal operation instruction and the position information corresponding to the cursor, and then take the primitive corresponding to the position information of the cursor as the target primitive. For example, it is determined that the position information of the cursor corresponding to the withdrawal operation instruction is the upper left area of the BIM software. If the BIM software is opened in full screen, the position information of the cursor is located in the upper left area of the screen of the terminal device at this time. If the position information corresponding to the cursor exists in primitive A, it means that the cursor is located on primitive A at this time, and therefore primitive A can be taken as the target primitive.

[0061] In other implementations, if the position information corresponding to the cursor of the withdrawal operation instruction is not on the primitive of the BIM software, it is determined that the withdrawal operation instruction is invalid. At this time, the terminal device will not respond to the withdrawal operation instruction, that is, only when the cursor of the withdrawal operation instruction is in the area of the BIM software, the withdrawal operation instruction will be responded, which is beneficial to avoid misoperation.

[0062] Step S300, according to the target primitive and the withdrawal times information, determining the target timestamp information corresponding to the target primitive after executing the withdrawal operation instruction according to the withdrawal times information, and modifying the current parameter information of the target primitive to the target parameter information corresponding to the target timestamp information.

[0063] When the target primitive and the withdrawal times information are determined, it is known at this time which primitive needs to be operated several times. The embodiment can determine the target timestamp information corresponding to the target primitive after executing the withdrawal operation instruction according to the withdrawal times information. The target timestamp information reflects which previous state the target primitive needs to be withdrawn to. When the target timestamp is determined, the embodiment can obtain the target parameter information corresponding to the target timestamp, and then modify the current parameter information of the target primitive to the target parameter information corresponding to the target timestamp information, so as to complete the withdrawal of the target primitive.

[0064] In one implementation, the embodiment in executing the withdrawal operation includes the following steps:

[0065] Step S301, obtaining the primitive ID corresponding to the target primitive, and determining all timestamp information corresponding to the primitive ID and the parameter information corresponding to each timestamp information based on the primitive ID;

[0066] Step S302, based on the withdrawal times information and all timestamp information matching, determining the target timestamp information corresponding to the withdrawal times information from all timestamp information, the target timestamp information is the corresponding timestamp information of the target graph element after executing the withdrawal operation instruction according to the withdrawal times information;

[0067] Step S303, obtaining the parameter information corresponding to the target timestamp information, and taking the parameter information corresponding to the target timestamp information as the target parameter information;

[0068] Step S304, modifying the current parameter information of the target graph element to the target parameter information.

[0069] Specifically, the embodiment records each modification of each graph element in advance, records the timestamp information corresponding to each modification and the corresponding parameter information, so as to know the time corresponding to each modification of each graph element and the corresponding modification content. For example, when the BIM software is opened, the embodiment detects the state of all files in the BIM software through the Documnet Change event, detects the state of all files in the BIM software, and then determines whether the state of the file has changed, such as whether the graph element is added, deleted or modified. If there is a change in the file, the changed graph element can be determined. After determining the changed graph element, the parameter information of the graph element at this time and the corresponding timestamp information are recorded and saved in the database to ensure that the time of the change of the graph element and the change content are recorded. For example, the embodiment determines that the changed graph element is A, and records the timestamp information of the graph element A as June 10, 2022, 10:24:20. The parameter information corresponding to the graph element A at this time includes the position, shape parameter and size parameter of the graph element A at this time, and the corresponding relationship between the parameter information and the timestamp information is established and saved. Based on this, the embodiment can record the timestamp information and the corresponding parameter information of each change of each graph element, so as to directly call when performing the withdrawal operation on a certain graph element in the subsequent step.

[0070] When performing the withdrawal operation, the embodiment first acquires the graphic element ID corresponding to the target graphic element, and determines all timestamp information corresponding to the graphic element ID and parameter information corresponding to each timestamp information based on the graphic element ID, which are recorded and saved when each change of the target graphic element is monitored. Then, the terminal device matches the determined withdrawal times information with all timestamp information, determines target timestamp information corresponding to the withdrawal times information from all timestamp information, and the target timestamp information is the timestamp information corresponding to the target graphic element after performing the withdrawal operation instruction according to the withdrawal times information. For example, when the withdrawal times information is three times, the target timestamp information can be obtained by pushing back three timestamp information in time sequence from the back to the front according to all timestamp information. Then, the terminal device can acquire parameter information corresponding to the target timestamp information, and take the parameter information corresponding to the target timestamp information as the target parameter information. Finally, the current parameter information of the target graphic element is modified to the target parameter information.

[0071] Therefore, the embodiment can directly locate which previous state the target graphic element needs to be withdrawn to based on the timestamp information, and implement the withdrawal of the target graphic element through parameter modification, without always withdrawing the action, providing convenience for the user, and improving the work efficiency. Moreover, the embodiment does not delete the steps corresponding to the parameter changes between the current parameter information and the target parameter information of the target graphic element, and the user can still locate the corresponding parameter information based on the timestamp information to modify the current parameter of the target graphic element, thereby implementing single-item withdrawal of the target graphic element, without affecting the use of the user.
