The operation and effect of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows a conceptual diagram of the use of the program.

The data that constitute the premise for establishing the present invention are roughly divided into the drawing data and the process data.

Generally, the work of three-dimensionally forming a CAD drawing made up of two-dimensional drawings, establishing a process plan, and creating a process table are performed separately (S100).

Once these two pieces of data are created, the three-dimensional drawing data is associated with the process data to link the specific process activity to the specific three-dimensional drawing entity.

In the present invention, there are three methods for achieving the purpose of three-dimensional imaging of the process plan situation. First, there is a method of constructing a separate D / B combining process data and code of graphic data. Second, A method of attaching the process code to the base field, and a third method of becoming a visualized by attaching the drawing element to the process activity database.

When the linking of both data is completed, an environment where graphical process simulation can be performed is created (S200), and the progress of the construction according to the time can be displayed as a three-dimensional image according to the process data (S300)

FIG. 2 is an operational flowchart for constructing a three-dimensional graphic object associated with process data. As shown in FIG. 2, a two-dimensional drawing is generally constructed at the time of designing.

In this graphic simulation, the two-dimensional drawing is made three-dimensional so as to be displayed as a three-dimensional image (S210)

On the other hand, as a result of establishing the process plan, the process data is prepared (S240)

The basic concept of the present invention is that a process activity bit is connected to a specific graphic element, thereby realizing the entity of the activity which can not be represented by itself, as a three-dimensional image.

Accordingly, the graphic data is blocked in units of activities (S220), and an activity code is given to express a specific activity (S230).

FIG. 3 is a development conceptual diagram of the present invention for a graphical process simulation. As shown in FIG. 3, when an activity code is assigned to the block data, the environment for graphical process simulation is completed.

The graphic simulation of the present invention uses this blocked graphic data and process data.

As the initialization operation, the user inputs the simulation time (Date).

Then, all corresponding drawings are loaded (S310)

In this case, the job is classified into three types: a job started at a simulation time (S331), an job in progress (S332), and a completed job (S333).

The work started at the simulation time is not expressed on the screen, and the work in progress is not completed but the work in progress is gray, so the work progress is expressed and the completed work is expressed as the final color or image of the work itself (S354)

(S330) as a quick start date and an early finish in the process data table in comparison with the simulation time (date)

As a result of the search, an activity list corresponding to each job is extracted as a data set (S340)

In this data set, the activity code is searched for each record (S351) this time (S352), and data is retrieved (S353)

If the activity code to be searched is one of the above three types of work, the searched drawing data is expressed in gray or unique color or image on the screen according to the characteristics thereof (S354)

Graphical drawing data associated with the activity is drawn on the screen up to the last record of the extracted data set (S361)

[Effects of the Invention]

As described above, the present invention firstly provides a new methodology for linking process activities and graphic data to overcome difficulties in the technology required in the existing process management method, as a separate database (D / B ), The method of attaching the process code to the graphic database field respectively, and the method of becoming a visualized image of the elements by the process activity data base.
