Therefore, the 5D modeling preparation means 3 prepares 5D modeling in various ways. For example, a desired 5D modeling (5D drawing) may be modeled using a 5D modeling tool or an already made 5D modeling may be called.

The drawing dimension reduction means (5) is a part that reduces the dimension of the drawing to a desired type of 2D modeling with the 5D modeling prepared by the preparation means (3), as shown in FIG. 1, symbol generation of the prepared 5D modeling Module 11, block generation module 13, facility generation module 15, grid generation module 17, and isometric generation module 19 are automatically generated and classified into desired types by at least one module.

Prior to that, the drawing dimension reduction means 5 reduces and classifies the 5D modeling prepared by the 5D modeling preparation means 3 into 2D modeling of any one selected from piping, component parts, and equipment. At this time, the 2D modeling classified as a pipe, such as a pipe, is configured to extract location information and a connection ID from the 5D modeling. Here, the location information may represent x-axis, y-axis, and z-axis coordinate values on spatial coordinates or angle values on spherical coordinates. In addition, the connection ID represents a display character such as a number for connecting objects to each other, that is, 2D modeling. In addition, the 2D modeling classified into component parts is designed to extract the shape, location information, and connection ID. In addition, 2D modeling classified as equipment is configured to extract shape, location information, connection ID, and point of connection (POC) information. Here, the connection point information corresponds to information about properties related to the connection of facilities, for example, information about the fluid, flow rate, pressure or input/output of the connection point, and information about the material and size of the pipe.

In addition, facilities such as semiconductor manufacturing facilities are processed to have data properties by means of a point of connection box having connection point information of pipes. Here, the connection point information table represents data properties (name, utility, material, etc.) in the form of a table so that the information of the connection point can be automatically converted.

The block generation module 13 is a part that generates components and facilities other than pipes through 2D modeling with various views, for example, as shown in FIG. 2, components such as on-off valves, or as shown in FIG. As such, the tank-type facility is blocked with 2D modeling such as a three-dimensional view, a plan view, a bottom view, a front view, a rear view, a left side view, and a right side view. In addition, when an isometric block is required, as shown in FIG. 4, a component such as an on/off valve is blocked in an isometric view in eight directions.

The view generation unit 23 dimensionally reduces the 3D modeling extracted from the 3D modeling extraction unit 21 and converts it into 2D modeling. It can be converted into a view, or converted into an isometric view representing an isometric drawing as shown in FIG. 9 . In addition, the linearization unit 25 represents the plan view or the isometric view generated by the view generation unit 23 using lines so that it can be expressed in, for example, AutoCAD format. In addition, the selection unit 27 partially cuts or deletes unnecessary lines or lines that should not be visible among the plan view or the isometric view expressed as lines in the linearization unit 25 to organize and remove them. Finally, the blocking unit 29 corresponds to the 3D modeling first extracted by the 3D modeling extraction unit 21 above for 2D modeling expressed in a plan view or an isometric view where the lines are arranged and finished by the selection unit 27 block it up

The facility creation module 15 is a part that creates various facilities by 2D modeling. As shown in FIG. 1, it is similar to the block creation module 13 in that the object to be modeled in 2D is a facility, but shown in FIG. As described above, a facility modeled in 2D, for example, in the form of a tank, is created in six side views: a three-dimensional view, a plan view, a bottom view, a front view, a rear view, a left side view, and a right side view. 'In addition, the facility creation module 15 may create a development view of the facility, and may assign various information such as fluid flow rate of the pipe connection point to each view through the above-mentioned connection point information table.

The grid generation module 17 is a part that creates a grid when creating a drawing that requires a grid, such as an architectural drawing, and as shown in FIG. Automatically create a grid.

In addition, the isometric view generation module 19 is a part that generates an isometric view from the above 3D modeling, and as shown in FIG. 1, the symbol generation module 11, the block generation module 13, and the equipment generation module 15 ), and at least one of symbols, blocks, facilities, or 2D modeling constituting the grid generated by the grid generation module 17 is selected as necessary, and 2D modeling with an isometric view is created by combining them. However, the three-dimensional view generated by the block generation module does not necessarily have to have an isometric city angle of 2D modeling, but the isometric view generated by the isometric view generation module 19 must have an equilateral city angle. At this time. Each isometric view can be created with a single line or a double line, and in this case, one must be selected between a single line and a double line.

In this way, 2D modeling whose dimension is reduced by the symbol generation module 11, block generation module 13, facility generation module 15, grid generation module 17, and isometric generation module 19 is the corresponding module. automatically generated and classified.

As a result of the confirmation, if the type of drawing to be issued is determined, it is sufficient to select a 2D modeling suitable for the type of drawing determined through the subsequent process and issue a drawing of the specified type. However, if the drawings to be issued are not determined, all 2D modeling can be selected so that all types of drawings can be derived later.

The drawing type selection means 7 is a part for selecting a 2D modeling suitable for the type of drawing to be issued, and as shown in FIG. Select 2D modeling suitable for the type of drawing to be issued according to the request of

To this end, the drawing type selection means 7 allows the user to select at least one type of drawing desired to be output from among a group of drawing types consisting of system drawings, facility drawings, construction drawings, and isometric drawings.

The drawing means 9 is a part that outputs the 2D modeling selected and sent according to the desired drawing type in the drawing type selection means 7 as a drawing, as shown in FIG. 1, a system drawing drawing unit 31, It includes a facility drawing drawing unit 33, an architectural drawing drawing unit 35, and an isometric drawing drawing unit 37.

Therefore, the drawing unit 9 draws the corresponding drawing from the corresponding drawing unit according to the drawing type selected by the drawing type selection unit 7 above. In addition, the derivation means 9 includes various information such as location information extracted from the 5D modeling prepared in the 5D modeling preparation means 3, along with the 2D modeling corresponding to each of the drawing units 31, 33, 35, and 37 as above. It is also output as a drawing.

To this end, the system drawing drawing unit 31, when the system drawing is selected in the drawing type selection means 7, the symbol generated by the symbol generation module 11 and the equipment view generated by the facility generation module 15 correspond accordingly. With it, draw and print the drawing. For example, as shown in FIG. 5 , the system drawing drawing unit 31 may derive a right 2D modeling from a 5D modeling of equipment and piping on the left side of the drawing. In addition, the facility drawing drawing unit 33 has blocks generated by the block generation module 13 and grids generated by the grid generation module 17 according to the selection of the facility drawing by the drawing type selection means 7 above. Draw and print the drawing. At this time, as shown in FIG. 6 , for example, the facility drawing drawing unit 33 may draw the 2D modeling on the right side in various views from the 5D modeling on the facility on the left side of the drawing. In addition, the architectural drawing drawing unit 35 has a block generated by the block generation module 13 and a grid generated by the grid generation module 17 according to when the architectural drawing is selected in the drawing type selection means 7 above. Draw and print the drawing. Even at this time, as shown in FIG. 7 , for example, the architectural drawing drawing unit 35 may derive a 2D modeling on the right from the 5D modeling of the building grid on the left on the drawing. Finally, the isometric drawing drawing unit 37 constructs and outputs a drawing with the isometric view generated by the isometric drawing module 19 according to the isometric drawing selected in the drawing type selection means 7 above. Similarly, the isometric drawing drawing unit 37 may derive a right 2D modeling from the left conformal 5D modeling on the drawing, as shown in FIG. 8 . However, before drawing the 2d modeling in this way, as shown in the upper right corner of the drawing, it is possible to select whether the isometric view to be drawn is a single line or a double line.
