Embodiment 1
[0049] Such as figure 1 As shown, the method for viewing reference changes of CAD graphics in an editable drawing environment includes the following steps:
[0050] For the convenience of description, the current drawing artist is set as A, and the referenced party is B;
[0051] B draws his own drawing (S01), submits the drawing to the server (S02), and the server will record a version B1 (S03);
[0052] A draws his own drawings and cites B's work results. The citation process will copy and superimpose the content of B on A's drawings, and A can refer to the contents of B when drawing his own drawings (S04);
[0053] B modifies his drawing and submits it to the server again (S05), and the server records the second version B2 (S06);
[0054] A updates the referenced drawing, and what A sees at this time is the latest state of B's drawing (S07);
[0055] A checks the changes, the system will compare the first and second versions (that is, B1 versus B2), analyze and obtain ...
Embodiment 2
[0058] To simulate an application scenario of the present invention, two CAD users A and B work together. A draws the file a.dwx, B draws the file b.dwx, A quotes / refers to the work results of B, and draws an outer frame to surround the content of B, such as image 3 As shown, the current status of b.dwx is as follows figure 2 shown. The circle 202 and the square wireframe 204 are the contents of b.dwx, and A draws a surrounding wireframe 302 around it. It should be noted that at this time, A cannot modify the content of the referenced b.dwx, that is, the circle 202 and box 204 in the box 302 cannot be modified, and belong to the content of the referenced file - for example, the downstream water supply and drainage engineer can only refer to Upstream construction engineers draw architectural CAD drawings to draw their own water supply and drainage drawings, and usually do not have the authority to modify and adjust the construction engineer's drawings.

Embodiment 3
[0062] The invention discloses a method for viewing reference changes of CAD drawings in an editable environment, which is characterized in that it comprises the following steps ( Figure 7a ):
[0063] S101 acquire the first file and the second file;
[0064] S102 The first file refers to the second file, and superimposes the first element on the second file into the first file;
[0065] S103 acquire a third file;
[0066] S104 Acquire a first change element of the third file compared with the second file; and, S105 superimpose the first change element into the first file.
[0067] In some embodiments, on the first file, the superimposed first element is displayed in a first display manner; and the superimposed first change element is displayed in a second display manner. According to the situation of different application scenarios, the first display and the second display may adopt different colors, different line styles (for example, virtual and solid, thickness), and d...
