the collaborative drawing method based on the CAD platform is known from FIG. 2, and comprises the following steps:
and S1, collaborative planning.
In this embodiment, the collaborative plan mainly performs collaborative staff plan and collaborative staff authority management. Firstly, a collaboration initiator uploads a base map file to be collaborated to a file server, adds collaboratively participating personnel and configures the authority of each collaboration personnel on each map layer, wherein the collaboratively participating personnel comprise read-only and read-write. When the authority is read only, the cooperative personnel can only perform read-only operation on the layer, cannot modify the object of the layer, and cannot add the object on the layer; when the authority is read-write, the cooperative personnel can edit the object on the layer, add the object on the layer, and modify the attribute of the layer, such as renaming, modifying the printing style, modifying the color and the like, and delete the layer. In addition, all cooperative personnel can add a new layer, the layer creator has read-write permission on the layer, and other people only have read-only permission on the layer.
The permission management strictly controls the condition that multiple persons cannot modify the same layer at the same time, and when the cooperative initiator modifies the permission for storage, the permission is verified, namely, the condition that the multiple cooperative persons have the permission to read and write at the same time does not exist in the same layer is ensured.

and S21, when the current collaborating personnel open the current drawing to be collaborated, synchronizing the editing authority of each collaborating personnel on each layer in the current drawing, which is configured in advance, from the authority management server.
And S22, when the current collaborator edits the current drawing, capturing the current drawing layer edited by the current collaborator in real time by registering an event reactor, and judging whether the current collaborator can edit the current drawing layer according to the preset editing authority.
The event reactor can detect the operation of the current cooperative personnel in the CAD platform and classify the object modification caused by the operation. The method mainly adds a layer reactor and an object reactor. The process of authority control by the event reactor is shown in fig. 4.
And S23, if yes, allowing the current collaborators to edit the current layer, wherein each layer only allows one collaborator to edit.
The editing of the drawing includes events such as adding, deleting and modifying primitive objects, which are all writing operations on the drawing, so that current collaborators need to have read-write permission on the current layer. At this time, the editing authority is synchronized to the front of the authority management server for authority verification, so as to ensure that there is no conflict in authority, therefore, in the step S23, when the authority management server verifies that there is no edit by other people in the current layer, the current collaborator is allowed to edit the current layer.
And S3, collaborative submission.
Wherein, step S3 specifically includes: and when the collaborative submission event is triggered, judging whether a primitive changes between the drawing data submitted this time and the drawing data submitted last time according to the handle and the attribute of the primitive, and if so, recording the changed primitive to generate a first primitive file.
The handle is uniquely allocated when the primitive object is created, and the modification of the same primitive object cannot cause the change of the handle but only the change of the attribute of the primitive object. The primitive file is mainly stored in a format of star, dwg, and can also be stored in other drawing formats, such as dxf, json and the like, and all newly added and modified primitive information is stored in the primitive file.
As shown in fig. 5, for step S3, the collaborative client is started to synchronize the registration collaborative timer, and a timing interval is set to trigger the collaborative commit event. When the collaborative submission is performed, firstly, a drawing comparison tool is used to obtain the difference from the last submission to the current submission, a primitive file and a collaborative data object are formed, and meanwhile, the modified content is synchronized to the current collaborative file. And uploading the graph element file to a file management server so as to avoid conflict caused by simultaneously modifying the same drawing and reduce data volume, and modifying the collaborative file in the file server.
The drawing comparison tool mainly judges whether the attribute of the same object ID is modified or not by traversing all the primitive objects in the two versions of drawings to obtain the added, modified and deleted objects. It should be noted that the comparison between the two versions of drawings is the comparison between the drawing data, not the comparison between the two presented images, and whether the addition or deletion is determined by the change of the front and rear handles, and whether the modification is determined by the change of the attributes under the handles.
In this embodiment, the trigger time for the collaborative submission of the event further includes when the current drawing is closed and when the current drawing is submitted, and in other equivalent embodiments, one of the three trigger times may be selected for use or two of the three trigger times may be selected for use according to actual requirements.
And S4, updating in a coordinated manner.
Wherein, step S4 specifically includes: and performing collaborative updating on other collaborative clients according to the first primitive file.

that is, the cooperative data structure includes a data header and a metafile, wherein the data header has a basic structure as follows:
in the data information head structure, the primitive object mainly records the Handle of the primitive in the drawing, namely Handle, and since the primitive changes, namely primitive deletion, addition and modification operations, a deleted primitive object set, an added primitive object set and a modified primitive object set correspond to each other.
And S42, sending the first primitive file to the file management server, and sending the collaborative update message to other collaborative clients, so that the other collaborative clients download the first primitive file from the file management server for collaborative update according to the data information header in the collaborative update message.
Therefore, after the collaborative submission, all collaborative personnel receive the collaborative update message at the collaborative client, and after the collaborative client receives the collaborative update message, the data information header in the collaborative update message is analyzed to obtain the reviewer, the added object, the revised object, the deleted object and the corresponding primitive file, then the primitive file is synchronously downloaded from the file server, then the added object and the revised object are respectively copied from the primitive file to the current collaborative file, and meanwhile, the object to be deleted is removed from the current collaborative object.
