Further, as shown in fig. 10, in a case where the user selects the my friends option, the contact list interface 1002 displays a plurality of account information having account association relationship with the CAD client operation account of the user, such as "me (187 xxxxxxxxxx)", "king (132 xxxxxxxxxx)", "tabloid (153 XXXXXXXX)".

The user can select to execute the execution operations of adding friends, deleting friends, editing friends and the like under the friend option, wherein the friend adding mode of the user can be but is not limited to initiating friend application by inputting mobile phone numbers of other contacts and the like.

Further, as shown in fig. 11, in a case where the user selects the group option, the address book interface 1102 displays a group (1) "a item group" created by the user and a group (1) "B item group" joined by the user, where the a item group includes 3 accounts: "me" (cell phone number 187 XXXXXXXX), "queen" (132 XXXXXXXX), and "sheetlet" (153 xxxxxxxxxx), this B-project group includes 11 accounts for "me". The address book interface 1102 also includes user-executable operation options, including "create group", "edit group", "delete group", "determine", and "cancel".

To further illustrate, in the scenario based on the address book interface 1102 shown in fig. 11, in a case where the user clicks on creating a group, as shown in fig. 12, the address book interface 1202 displays a group name to be filled in by the user and information of group members to be invited by the user. The user can invite a friend to join the group, or invite other non-friend or non-registered users to join the group through the mobile phone number, where when inviting a non-registered user through the mobile phone number, the user may, but is not limited to, simultaneously register for the non-registered user and send an invitation message, or send a message confirming whether to register or receive the invitation message for the non-registered user, which is not specifically limited in the embodiment of the present application.

step S1304, adding personnel by the user to determine group member objects included in the successfully created group;

step 1306-step 1308, in the case that the user adds a non-friend to the group, requesting to add a friend by inputting the CAD client identification information (for example, a mobile phone number) corresponding to the non-friend user, and sending a short message to the friend to confirm that the friend is added to the group;

step 1310, when the user adds a friend to enter the group, inviting is carried out based on friend relation information in the address list;

step S1312-step S1314, when the user adds unregistered personnel to enter the group, the account is registered to the cloud terminal by inputting the information of the mobile phone number corresponding to the unregistered personnel, and the user invites the group to enter;

step S1316, after the user completes the personnel adding operation, establishing a group relation;

step 1318, uploading the group relationship to a cloud.

According to the embodiment provided by the application, the account establishing request triggered by the first account is responded, and the cloud server is used for establishing the target account group.

and step S1416, displaying the CAD data transmitted by the user on the CAD client corresponding to the receiving end based on the first CAD data and the second CAD1 data.

As an optional scheme, based on the inbox function in the data transmission module 306 shown in fig. 3, as further shown in an inbox interface 1502 of fig. 15, CAD data records sent by the user or another user are stored in the inbox of the user, and the user may perform corresponding downloading or opening of a drawing file in a DWG format, view or load or export annotation information, and delete some or all of the CAD data records by selecting one of the CAD data records.

Optionally, in this embodiment, the user may select to load annotation data corresponding to the selected CAD data record into the current project file of the user, and update annotation data transmitted by others into the current project file in real time, so as to achieve the purpose of improving correspondence between the user and other users for rapid, accurate, and efficient CAD data update, thereby improving data transmission efficiency of the CAD client of the user.

It should be noted that, when the identification ID (for example, a file name) corresponding to the selected CAD data is inconsistent with the current project file, the CAD client prompts "whether to continue or not inconsistent with the current project file identification ID".

As an optional scheme, the data transmission method of the CAD client is applied in a scenario of mass-sending data by a user, and specifically includes the following steps:

step S1602, a user logs in a CAD client through an account related to the CAD client;

it should be noted that after a user completes account registration of a CAD client, the CAD client creates a unique account ID for each user, and when the user logs in using an account, after the user identifies and passes through the account ID, the CAD client obtains relevant data of the account ID from the server, such as friend account information, creation group information, joining group information, and the like of the account;

it should be noted that, when a user establishes a group, the server stores the group information as tag data, and then adds the tag data to account ID data of the user in the group;

when the user logs in, the user acquires group data from the server, synchronizes the group data to the front-end interface and displays the information of the group and the personnel in the group;

step S1604, after the user successfully logs in the CAD client, whether the user account has a group relation is obtained;

step S1606, under the condition that the user account does not have the group relation, the group display is null;

step S1610, a user selects group sending personnel, a drawing file and annotation data;

step S1612, uploading group sending personnel, drawing files and annotation data to a server;

step S1614, the server distributes the drawing files and the annotation data to corresponding mass-sending personnel according to the group labels

Step S1612, completing the mass texting;

when the files are sent in a group manner, copies of the files to be sent in the group manner at the CAD client side are uploaded to the server annotation data, coordinate information, character information and the like are all stored as JSON format files and are uploaded to the server;

the server stores the JSON file of the paper file and the annotation data into the data of the account ID with the group tag according to the group tag; when data in the account number changes, the newly received drawing file and the JSON file are synchronized to a front-end interface from the server, and the mass texting function in the CAD is achieved.
