Within the zone database 30, coordinate information (maximum / minimum coordinate value) indicating the intersection relationship information and the zone in the zone box, editor, edition date, Area master information such as description is defined. The zone information stored in the zone database 30 has a logical connection relationship with the work model file and the zone box establishing device 40 when necessary in the zone related function of the zone function control section 41 for calculating the quantity of water.

FIG. 9 shows a part of a design model of a line segmented by a small unit. The procedure of creating a zone box selects a design model (corresponding to A in Fig. 9) of a subregion where the user will create a zone box, as shown in Fig. You can then select the lower hierarchy node in the section tree of the design model. Next, a window (zone box interface) for creating zones on the zone information providing unit 45 is provided, and basic information of the zones, that is, zone names and zone descriptions, can be inputted through the window. And the zone information providing unit 45 can be switched to the editing mode so as to input additional information of the zone.

The creation area is displayed and visualized on the model information providing part 43 and the created zone is added to the zone list.

The user can input the area coordinate information indicating the zone through the model information providing unit 43 (coordinate input by dragging the coordinates as described above) or zone information providing unit 45. [ The coordinates thus input are reflected and displayed in the zone box on the model information providing unit 43.

There can be more than one zone box in a small area, and an additional zone box can be created. Also, if you need to modify and delete the zone box during the creation of the zone box, you can modify / delete it if you have selected the corresponding zone box. When the creation / modification / deletion of the zone box is completed, the zone coordinate information of the zone box can be stored in the zone database 30, the zone list in more detail. Editing such as modification / deletion of the zone box can be performed by the zone information management unit 47 of the quantity calculation apparatus 40. [

When the creation of the zone box is completed in this way, the work model of the zone tree related to the volume of the small unit to be calculated prior to calculating the quantity should be loaded with logical connection.

(Hull, Pipe, Equip, STRUCT) related to the quantity of water based on the small area are loaded in the structural information providing unit 42.

When the model is loaded in the structure information providing unit 42, the work model is selected as a sub-region to be loaded. When a zone box is registered in the selected node, the zone coordinate information of the zone box is registered in the zone list, and the process continues until the lowest node.

When the zone list is completed, the zone box of the work model is loaded in the directory specified by the work model file.

The water quantity calculating unit 46 can calculate the total quantity required in the sub-area based on the absence position and the member name of the three-dimensional model information corresponding to the area coordinate information up to the lowest node below the selected specific node.

In particular, when the zone box is registered in a specific node, the quantity calculation unit 45 registers the zone box in the zone list, searches the lowermost child nodes to complete the creation of the zone list, It is possible to calculate the volume of the unit of the small area based on the zone list and the member list. In the case of a member option in which the option of including a zone box is partially included, only the partially contained member is added to the member list, and in the case of the completely contained member option, only the member which is completely included is added to the member list, .

At this time, based on the completed member list, the members that are not in the member list can be removed from the three-dimensional model information and removed from the region tree to visualize the members not on the member list on the screen. As a result, the quantity of the units in the small area unit is calculated based on the zone list and the member list.

A method of generating a zone box of a small area by using a water quantity calculating apparatus having such a configuration will be described with reference to FIG. At least one zone box in the sub-region can be created, and the zone coordinate information of the generated zone box is stored and managed in the zone database 30.

Referring to FIG. 3, the zone box generating unit 44 included in the quantity calculating apparatus 40 selects an object line from the user (S101).

The zone box generating unit 44 judges whether or not the zone tree divided by the structure of the object line, that is, the zone, the middle zone, and the sub-zone is stored in the zone database 30 (S103).

If the zone tree is stored in the zone database 30 as a result of the determination in step S103, the structure information providing unit 44 included in the volume calculation apparatus 40 calls the zone tree from the zone database 30, 1 on the screen (S105).

If it is determined in step S103 that the zone tree is not stored in the zone database 30, the zone box generation unit 44 generates a zone tree from the structure of the object arc, that is, the zone zone, the middle zone, and the sub- To be displayed on the first screen (S104). At this time, the names of the major, middle, and minor districts of the target line should be determined by the name indicating the location of the target line.

Thereafter, the zone box generating unit 44 selects a sub-region among the zone trees provided on the first screen (S107).

The zone box generating unit 44 displays the zone box interface on the third screen to generate the zone box of the selected small area (S109). At this time, if the area coordinate information of the sub-area is already stored, the stored area coordinate information is provided on the third screen and editing such as correction or deletion can be performed.

The zone box generating unit 44 displays the selected three-dimensional model information of the small area on the second screen (S111).

The above-described step S109 and step S111 are not limited to this order. If the zone box interface is displayed on the third screen before the step S113 described below and the three-dimensional model information of the selected small area on the second screen is displayed It can be implemented.

The zone box generating unit 44 receives the zone coordinate information to generate the zone box in the sub-zone (S113). Here, it is described that the user directly inputs the area coordinate information. However, the area coordinate information can be set by changing the size by placing the editing point on the surface of the area box and dragging the mouse.

The zone box generating unit 44 converts the received zone coordinate information into shipbuilding coordinate information (S115).

The zone box generating unit 44 reflects the converted shipboard coordinate information to the model information providing unit 43 (S117).

Thereafter, the zone box generating unit 44 determines whether or not the storage is requested (S119).

If it is determined in step S119 that the storage is requested, the zone box generating unit 44 stores the zone coordinate information of the zone box created in the zone database 30 (S121).

If it is determined in step S119 that the storage is not requested, the zone box generator 44 determines whether modification is requested (step S122).

If it is determined in step S122 that modification is requested, the zone box generating unit 44 moves the process to step S113 and receives zone coordinate information.

If it is determined in step S122 that modification is not requested, the zone box generating unit 44 maintains a standby state for a predetermined time.

After the step S121, the zone box management unit 47 included in the quantity calculation apparatus determines whether deletion / addition creation is requested (S124).

If it is determined in step S124 that deletion is requested, the zone box management unit 47 deletes the zone coordinate information of the generated zone box from the zone database 30 (S126).

If it is determined in step S124 that the additional generation is requested, the zone box generating unit 44 moves the process to the step S111 to select the zone box to be additionally generated. The three-dimensional model information of the sub- And displays it on the study 43.

Through the process described above, at least one zone box in the sub-zone is created and the zone coordinate information of the generated zone box is stored and managed in the zone database 30.

Hereinafter, a method of calculating the quantity of water in the unit of the area will be described.

FIG. 4 is a flow chart for explaining the method of calculating the quantity of water in the quantity calculating apparatus according to another embodiment of the present invention.

Referring to FIG. 4, the structure information providing unit 42 included in the quantity calculating apparatus 40 refers to the zone database 30 storing the predefined zone master information, (S201). ≪ tb > < / TABLE >

The quantity calculation apparatus 40 selects an arbitrary section to be calculated in the section tree indicated by the structure information provided to the structure information providing unit 42 (S203).

The quantity calculation apparatus 40 determines whether a zone box exists in a lower node of the selected zone (S205). 6, when the selected region is the middle region (PORT RONTOON_FWD), the quantity calculation apparatus 40 searches for a zone box of a subregion, which is a lower node of the middle region, i.e., the lowest node in the middle region, It is determined whether or not a zone box exists. If a subregion called ACCSS TUNNEL is selected, it is determined whether or not a zone box exists in the selected subregion. At this time, the quantity calculation apparatus 40 can search up to the lowest node below the zone, and display the zone tree on the basis of whether the zone box exists or not. As shown in FIG. 6, when an arbitrary region, that is, PORT COLUMN_FWD is selected, it is searched whether there is a zone box at the lowest node below the selected zone, and whether the zone box exists or not is adjacent to the corresponding lower node Can be displayed. The check box indicates the lower node of the selected node, and the box next to the check box indicates the presence / absence of the zone box.

If the zone box does not exist in the lower node of the selected zone as a result of the determination in step S205, the quantity calculation device 40 moves the process to step S209 described later.

If the zone box exists in the lower node of the selected zone as a result of the determination in step S205, the quantity calculation device 40 registers the zone coordinate information of the zone box in the zone list (i.e., the volume to be calculated) And creates a zone list (S17).

Then, the quantity calculation device 40 judges whether or not the next node is selected (S209). Here, the next node means a zone located at the same level as the zone selected in step S203 described above.

If it is determined in step S209 that the next node is selected, the quantity calculation apparatus 40 moves the process to step S205 to determine whether a zone box exists in a lower node of the next node.

If it is determined in step S209 that the next node is not selected, the quantity calculation device 40 determines that the creation of the zone list is completed, and the zone containing option of the zone box (S211), the member included in the zone box is added to the member list. The member list may include information about equipment belonging to the zone. For example, if the option to include a section is an option with a portion, the partially included member is added to the member list, and if the option is included completely, only the completely included member is added to the member list.

When the creation of the member list according to the option including the zones is completed, the quantity calculation device 40 removes the members not in the member list from the block tree displayed in the structure information providing portion 42, The member is unloaded (S213).

Then, the quantity of water calculation device 40 calculates the total quantity of the required quantity in the area selected in the above-described section tree based on the created area list and the member list (S215). For example, if the area selected in the section tree is a sub-area, it is possible to calculate the necessary quantity in the sub-area. If the area selected in the section tree is, for example, a middle area, Can be added to calculate the total quantity of the middle region.

By doing this, it is possible to calculate the quantity of the unit of the zone based on the position and the member name of the member included in the three-dimensional model information of the object line corresponding to the area coordinate information of the zone box in the small area, In addition to enabling job management and work order creation, it is possible to utilize the quantity of small-unit units in the process management in the post-production department, thereby improving the overall production quality.

In the above description, when an arbitrary region is selected in the section tree, the 3D model information of the selected region is displayed on the second screen, and it is determined whether there is a section box at a lower node of the selected section. Dimensional modeling information having the coordinate information coinciding with the coordinate information of the three-dimensional modeling information, and the position of the member. However, in another embodiment, the quantity of the product can be calculated through visualization of the model.

Prior to calculating the quantity, the work model has a logical connection to the section tree associated with the quantity of the small unit to be calculated.

The method of calculating the quantity of goods through modeling of an industrial model selects an arbitrary node to which an industrial model (Hull, Pipe, Equip, Struct) is to be loaded by loading a block model of the object row provided by the structural information providing unit 42. If the zone box is registered in the selected node, the zone coordinate information of the zone box is registered in the bounding box list of the model. Then, the next node exists If not, loads the work model file list in the directory where the work model file (see FIG. 10) is stored, loads the bounding box of the work model in the work type file header, and extracts the area coordinate information of the section box from the loaded bounding box list.

10 shows the definition file of the PE / Block structure of the object line and the work type model file of each block. In FIG. 10, 102 blocks are selected and the work model file of the selected PIPE is selected from among the selected 102 block types, that is, HULL, EQUIP, STRUCT and PIPE.

If the option in the corresponding zone is a complete include option and the bounding box of the working model is completely included in the zone coordinate information of the zone box, the option file is satisfied. In other cases, if the option of the corresponding zone is not completely included and the bounding box of the working model is at least partially included in the zone box information of the zone box, the option file is added to the file open list.

In other cases, that is, when the bounding box of the working model is not completely included even though the area option is completely included. If the bounding box of the working model is not included in the area coordinate information of the area box, Do not add model files.

If the zone coordinate information of the zone box exists in the bounding box list of the model, the zone coordinate information of the zone box is extracted again on the bounding box list of the model, and if the next work type file exists on the work type file list, The process of loading the bounding box of the work model is repeated.

When this process is repeated, the work type file added to the file open list is loaded and the work type model loaded on the second screen is visualized. In this case, since the logical connection relation between the work type model and the zone box is defined, the quantity of the selected node can be calculated based on the member name and the position of the member of the work model corresponding to the zone coordinate information of the zone box.

The invention being thus described, it will be obvious that the same way may be varied in many ways. Such modifications are intended to be within the spirit and scope of the invention as defined by the appended claims.
