With the improvement of computer hardware technology, the size of the drawing file may be larger in the future.
  • professional engineers need to constantly refer to each other's CAD drawings to draw their own drawings (for example, water and drainage engineers must refer to the drawings being drawn by the construction engineer and not yet completed when drawing water and drainage CAD drawings.
  • CAD systems have many disadvantages in file management, transmission, and storage, as well as file reference functions (for example, external references): for example, CAD files have a large amount of data storage and transmission costs, low efficiency, and CAD It is often inconvenient for users to view versions of CAD files created and edited at different times.
  • the present invention provides a new type of CAD collaborative design system, including four sub-inventions (namely, the A invention, the B invention, the C invention, and the D invention) and various modifications and extensions based on the four sub inventions.
  • the invention first discloses a timeline management system (and method, computer storage medium, and computer terminal) for a CAD file, which is characterized by comprising: a first data summary file and an incremental database; the first data summary file includes A first data item index table and first data summary information; the incremental database stores first data detailed information corresponding to the first data summary information; the first data item index table is used for the increment The database is searched for the first data detailed information corresponding to the first data summary information; and the data summary file is set to be associated with a first restore point.
  • the invention adopts the way of data summary file and incremental database for CAD file management. It can not only reduce the amount of data transmission during file restoration by transmitting incremental data, but also quickly and completely through the information preservation integrity of the data summary file. Accurately restore CAD files.
  • the present invention also discloses a method for quoting external files in a CAD system, a quoting device, a computer-readable storage medium, and a computer terminal.
  • the quoting method includes the following steps: creating at least one first general reference rule file independent of the referenced file according to at least one quoting condition, and storing it independently in an extensible file format; and according to the selected at least one first general reference rule
  • the reference rule file references at least one of the referenced files.
  • the invention adopts a reference rule file independent of the referenced file, which can not only be used repeatedly by the user, avoid repeated setting of reference conditions, and improve the efficiency and accuracy of the user's collaborative drawing operation.
  • the present invention also discloses a hierarchical operating system (and method, computer storage medium, computer terminal) referenced by a CAD system, which is characterized by including: a first file including at least one first element; a second File containing at least one second element; the at least one first element is copied and superimposed into the second file; the at least one first element is associated with a first control point, and can be achieved through the first control point Independent operation on the at least one first element.
  • the present invention solves the problem that it is difficult to convert the nested content display mode in the external reference method in the existing CAD system (that is, in the overlay type and the additional type), so that CAD users can conveniently and quickly choose to display or hide the nested content, allowing multiple Hierarchical drawing reference / reference is more convenient and fast, which improves the work efficiency of CAD drawing collaborative design.
  • the present invention also discloses a method (and system, computer storage medium, and computer terminal) for viewing changes in a CAD drawing in an editable environment, which includes the following steps: DS101 obtains a first file and The second file; the first file in DS102 refers to the second file, and the first element on the second file is superimposed on the first file; DS103 obtains the third file; DS104 obtains the third file. The first change element of the second file is described; and the DS 105 adds the first change element to the first file.
  • the present invention allows a CAD drawing user to check the update of the referenced drawing while continuing to edit the current CAD drawing, thereby solving the need to display and view the referenced drawing change outside the current CAD drawing in the existing CAD system. Returning to the technical problem of continuing to edit the current CAD drawings, the convenience and efficiency of CAD collaborative design have been improved.
  • the CAD collaborative design system provided by the present invention allows CAD files to be stored in a timeline, and versions created, modified, and updated at different times can be easily restored and consulted quickly;
  • the form which reduces the amount of data transmission, also ensures the accuracy of file restoration, and improves the efficiency of the entire CAD system in file management.
  • the new reference method not only allows CAD drawing engineers to easily filter the content of the referenced files, but also allows them to share the reference rules set by themselves to other collaborators; and the multi-level display method avoids the existing external reference embedding. Many problems generated by the set increase the flexibility when referring to external files.
  • the present invention realizes editing the current file by copying and superimposing the referenced content (which can be filtered and selectively displayed) into the currently edited CAD file. Synchronize and view the changes of the referenced content with the same interface, making collaborative work more convenient and efficient.

Such systems treat the information they hold as a set of basic files and the differences that each file accumulates over time.

When tracing the historical version, you need to start from the basic file, merge the differences at each restore point in order, and finally restore the user's required file version.

  • the electrical engineer edits his own electrical drawing 914, he can submit his own electrical drawing 914 to the timeline storage device in the server.
  • the timeline storage device compares the electrical drawings before and after the modification by the electrical engineer, and The changes are saved to the incremental database in the form of incremental data, and a new data summary file and a restore point 904 associated with it are formed.
  • the restoration point 904 is located on the timeline 903, which is a global timeline of the collaborative design project in which the electrical engineer participates (that is, each restoration point includes all the CAD files related to the project at that time point).
  • Point 905 is the earliest electrical drawing drawn by an electrical engineer. If an electrical engineer needs to view the earliest drawing, he only needs to obtain the data summary file from the restore point. The detailed information of the CAD elements recorded in the data summary file can be obtained from the incremental database, so that the earliest drawing can be restored quickly and accurately. Electrical CAD drawings.
  • the computer terminal where the electrical engineer works can identify the differences between the new and old versions of the electrical drawings, and upload the detailed information of the incremental data corresponding to the differences to the server In the incremental database, the pressure of data transmission is reduced.
