　Can make 　 　 　 　 dimensions 　 can 　 use 　 three-dimensional 　 shape 　 from the planning stage of the building.

The 　 location information 13 is 　 information about the 　 position of the 　 object of the 　 two-dimensional 　 graphic 　 drawing, where the 　 hierarchical spatial information described above is 　

Using the example of the case of the building structure, it is as follows. If 　two-dimensional 　 CAD 　 　 object on the drawing 　 hierarchical spatial information 　 specific 　

If it is a shave, 　 immediately 　 below 　 sub 　 geospatial information is 　 in the same 　 room as 　 warehouse, 　 library 　, 　 right 　 top 　 upper 　 spatial information

It is applicable to the east. These 　 upper 　 and 　 sub 　 spatial information 　 related 　 two-dimensional 　 CAD 　 drawings are 　 many 　 drawings can be 　 　 can 　 these 　 two-dimensional 　 CAD

The drawings are 　to each other 　 reference point 　 set 　 not 　 　 by a specific 　 reference point 　 to be connected 　 to each other 　 specific 　 reference point 　 position

　 is necessary 　 and 　 these 　 reference points 　 information 　 seen 　 in the invention 　 it is called location information (13), and 　 by the operator 　 keyboard 　 or

It is entered into the coordinate input device. In fact, in the 　this 　in the 　 system, 　internal 　 coordinate values 　, and 　2D 　 CAD 　 drawings 　 angles 　

　 is characterized by 　 that is 　 about the body 　 　 relative 　 location 　 has 　 features 　, as will be described later 　 different from 　 above 　 hierarchical spatial information 　 also 　 two-dimensional 　 CAD

　 not included 　 in cotton 　 it is stored separately 　 in the 　 system 　 of the invention 　 to be used 　 as needed 　

The 　object characteristic information 12 is 　information about 　for 　 specific 　 part of 　 two-dimensional 　 graphic 　 drawing 　 to which 　 hierarchical spatial information described above is 　

The object characteristic information is 　 in the case of an architectural structure 　 example 　 　 is as follows 　. If 　 above 　 two-dimensional 　 graphics 　 drawings 　

For the main 　 floor 　 　 work 　 case 　 group 　 sub 　 spatial information 　 library, 　 warehouse 　 and the same 　 room 　 and 　 reminder 　 warehouse and the same worker

If specified, the number corresponding to the separate 　 code 　 and 　 group 　 and 　 that indicates the room 　 through a separate 　 program 　 in the task window 　

　 to build 　 to construct 　 to build 　 to build a warehouse 　 to form a specific 　 part 　 to form a 　 deadline 　

There are 　 information about 　 details 　 such as 　 floor, 　 mop, 　 wall, 　 ceiling 　 and 　 molding 　 etc. Specifically, the mop

Objectives 　 height, 　 material code 　 and 　 price 　 will be 　, and these 　 object property information is entered by 　 by the operator 　 through 　 separate 　 program 1 　

This is 　 shown in Fig. 4e. The 　 object characteristic information 12 is included in the 　 two-dimensional 　 graphic 　 within the 　 original 　 　 system 　, and 　 these 　

The body characteristic information is 　 combined with 　 surface shape information 　 and 　 location information 　 to form 　 logical 　 three-dimensional 　 data which will be described later.

The 　 logical 　 three-dimensional 　 data 　 means (20) for generating 　 　 hierarchical spatial information 　 and 　 object characteristic information 　 included 　 two-dimensional 　 CAD 　

　 means 　 specific 　 program 　 2 that combines 　 extracted 　 surface shape information, 　 original 　 system 　 stored 　 location information, and 　 these 　

The two-dimensional 　 graphic 　 　 object 　 will be implemented 　 space, 　 position 　 decided 　 group 　 object 　 actually composed 　 specific 　 surface (surface shape information)

There is 　 this in three dimensions 　 can be implemented 　 through the output device 　. At this time, the 　 position of the 　 object is 　 inside the system 　

The reference point is 　already 　, but the actual 　 is displayed 　 three-dimensional 　 shape 　 the reference point is not fixed 　 but these are 　 three-dimensional 　 shape 　

By not setting the displayed 　 reference point 　 in advance 　 　 same 　 object 　 duplicated 　 system 　 internally 　 not formed 　 effect

There is. In other words, if the 　 worker selects 　 that contains 　 each 　 room 　 　 specific 　 floor (e.g. 　 1 pack) 　, 　 the above 　 configures the 　 　 on each 　 part

As 　 is combined, 　 the system 　 internally 　 three-dimensional 　 shape 　 is created, and 　 above 　 specific 　 and other 　 layers (e.g. 　 2nd floor) 　 If you select 　 from the 1st floor

　 the same 　 each 　 part information is 　 again 　 above 　 2nd floor 　 is newly combined 　, and separate 　 information is 　 combined 　 because it is not 　 same 　

The beam is duplicated, and there is no need to be stored in the system, so it is very effective to provide a three-dimensional shape and to be able to provide it.

As described above, when 　 logical 　 three-dimensional 　 data is created, it is necessary to 　 to 　 to a specific location 　 to express 　 3 dimensional 　 shape 　.

Such 　actual 　3D 　To express 　 shape 　 Logical 　 3D 　 Data 　 As it is 　 Can not use 　 No, 　 Workers want 　 Location

It is necessary to convert 　 to a 　 following 　 real 　 physical 　 three dimensional 　 shape 　 line 　. This is 　Logical　3D 　Data 　Worker knows　from real location

This is because 　can be seen 　 data 　 does not exist 　. This is 　by a separate 　 program 　2 　 this 　 in the 　 system 　 automatically 　

　 is not 　 separate 　 work 　 is necessary 　, and in this invention, it is a means (30) that creates 　 physical 　 three-dimensional 　 graphics

It is implemented on the system, through a specific program 2. Workers 　 desired 　 location, 　 for example 　 hierarchical 　 　 embedded in spatial information 　

If you select a specific 　 complex, 　 tool, 　 building, 　 floor 　, etc. 　in a separate 　 input window, use 　 input devices such as 　 keyboard, 　 mouse, and 　

Through 　, the worker wants 　 3D 　 shape 　, that is, 　physical 　 3D 　 data 　 is derived. This allows the 　worker to 　to the desired 　

Three-dimensional 　 shape can be 　 easy 　 check 　 　 can 　, and 　 various 　 different 　 information 　 added 　 to these 　 three-dimensional 　

Ra　To be able to use 　 　 base 　 prepared 　. This 　physical 　 three-dimensional 　 shape 　 was derived 　 　 showing 　 is also 4g.

The 　 3D 　 data 　 production 　 method using 2D 　 graphic drawings is:

　 for a given 　 architecture 　 or 　 manufacturing field 　 two-dimensional 　 graphics 　 drawings 　 keyboard 　 and 　 coordinate input devices and 　 input devices such as 　

On the 　 able 　 　 computer 　 system to operate 　,

Steps in which the 　 hierarchical spatial information of the 　 implemented 　 object on the 　 two-dimensional 　 graphic 　 drawing is 　 entered in the system 　 and stored 　 by a separate 　 program 　

(s10);

　 step (s20) in which 　 location information is input 　 and 　 in the 　 two-dimensional 　 graphic 　 drawing 　 implemented 　 object 　 by using a separate 　 program 　

The 　two-dimensional 　 graphic 　 drawing 　 is designated 　 using a separate 　 program 　, and object characteristic information is 　 on the specified 　 object

In the 　 input 　 and 　 stored 　 step (s30);　 step of combining 　 hierarchical spatial information 　 and 　 object characteristic information 　 using a separate 　 program 　 to the 　 two-dimensional 　 graphic 　 drawing 　

(s40);

The above 　 hierarchical spatial information 　 and 　 object characteristic information included 　 two-dimensional 　 graphic drawing 　 　 object 　 surface shape information 　 separate 　 program

After the 　 generated 　, 　 the 　 location information is included 　 logical 　 three-dimensional 　 data 　 is generated 　 step (s50);

The 　 logical 　 three-dimensional 　 data 　 by using a separate 　 program 　 to the 　 output device 　 physical 　 three-dimensional 　 data 　 step (s60);

Including 　, and 　for architectural structures 　 2D 　 Graphics 　 Using drawings 　 3D 　 Shapes 　 Forming 　 Methods 　 As a specific example 　 Based on Figure 4

Explain it.

The above 　 s 10 steps 　 to s 60 　 steps is based on a system that can be edited by a worker in a two-dimensional graphic 　 drawing 　 already 　 completed 　 status 　

　, and 　 on these 　 system 　 　 monitor and 　 same 　 output device 　 two-dimensional 　 graphic 　 drawing 　 displayed 　 　 states 　 described

(Of course, the 　worker can 　 work even in the 　referred 　 two-dimensional 　 graphic 　 drawing 　 displayed 　 on the monitor 　 not 　 　 can 　, and 　 is hierarchical construction

　 to input liver information, 　 location information, 　 object characteristic information, etc. 　 by the program 　 two-dimensional 　 graphics 　 drawings and 　 separate 　 because 　 can work 　

to be.)

[S10　 step]

The above step 　s10 is the 　referred 　 system 　 on the 　 two-dimensional 　 graphic 　 drawing 　 displayed 　 objects (in architectural structures 　 apartment 　 specific 　 floor

　 see the floor plan 　, and 　 these 　 objects belong to which dong/floor 　, and which 　 division (specific 　 　 　 floor map 　 several 　 drawings 　 can be made)

This is for 　 classification 　) 　 to include 　 　 as shown in Fig. 4a 　 by using a separate 　 program 　 1 　 using the provided 　 input window

This is the 　 step of registration, and you will enter 　 code 　 and 　 floor height 　 for 　 for each 　 building. Of course, 　hierarchical spatial information is at the 　 building/floor 　

There are 　　　　, and 　This is shown in Fig.4a, and it is not 　, but using this 　a separate 　input window 　each 　in the tool 　

Code 　 and 　 tool name 　, etc.) can be entered 　, and 　 also can be composed of 　 at the 　 sub-level 　 below the building/floor 　 　 household (furniture), 　 room (room)

　For each 　 household 　 and 　 room 　 　 code 　 and 　 name 　, and 　 above 　 room 　 case 　 equilibrium (or 　 square square meter) 　 can be registered 　

Like this, 　 hierarchical spatial information is 　 in accordance with the 　 object 　 　 the operator 　 from the highest level 　 the lowest level 　 spatial information 　 input 　

The details are 　 work purpose 　 and 　 depending on the details of work 　 can be changed 　 it is natural 　 will do.

At this time, the 　 worker can make 　 specific 　 consent 　 floor 　 certain 　 division 　 and specify 　 　, and these 　 division-specific work 　 in Fig. 4a 　 and 　 right of Fig. 4b

　 is marked on the column. This is 　 　 1 　 in 　 4a 　 and 　 4b in 　 1 　 each floor as 　 area 　, and the detailed names 　 4a 　 and 　 in FIG. 4b as 　AAAAAAA

Is done. In this 　 division 　 　 like Fig. 4c and 　 　 1 building 　 for each floor 　 for 　 sub-level 　

　 　 able 　 standards 　 prepared 　 will be.

When this 　 hierarchical spatial information is input and 　 is registered, it is 　 stored on the system 100 by 　 in a separate 　 storage device, and 　 these 　 information is 　 two-dimensional

Graphics 　 　 included 　 each 　 object 　 is connected by a separate 　 program 　 1 　, and 　 these 　 connection work 　 　 logical 　 two-dimensional 　

It will provide the basis for which data is 　 structured 　.

These 　 hierarchical spatial information 　 all 　 two-dimensional 　 graphic drawings 　 to respond 　 the operator 　 selected 　 registered 　. One　two-dimensional　graphic

Even if a drawing is 　 missing 　, it is because 　 final 　 3D 　 graphic drawings 　 not created 　 can 　.　Amend/Add 　Operation steps are required

It is necessary.

[S20　 step]

In the 　s20　 step, in the 　s10　 step, 　 classifies the 　 space where the building structure is 　, and enters 　 information about 　 in the 　 space and stores 　

In response to 　 forming 　 vertical 　 location 　 relations together, 　 inputting 　 information about 　 horizontal 　 position relation of 　 building structure 　 saving

Step. In other words, it is the step of providing information about 　 about 　 horizontal 　 and 　 about the 　 building structure, 　 building, 　 floor, 　 household, and 　

　 is stored separately on the stem, 　each 　 tool, 　 building, 　 floor, 　 household 　 and 　 setting the reference point 　 of the room 　 detail work details 　, and 　 each 　 tools 　 drawings

If this 　 is composed of several 　 　 　 group 　 　 relationship 　 and 　 upper level 　 and 　 between lower level 　 drawing 　 to be connected 　 number 　 to each other 　

Quasi-points are entered. This allows 　 to display 　 architectural structures 　 many 　 two-dimensional 　 graphics 　 drawings 　 vertical (hierarchical spatial information) 　 and 　

(Location information) As the location is set and connected, even if one 　 drawing is selected by the operator, the related 　 and the other 　 drawing

It is 　 natural 　 in the system.

Specifically, it is as follows 　.

The operator registers the 　 reference point of the 　 building structure 　 as a separate 　 program 　 1 　 by using the provided 　 input window 　 and saves it in the system.

Cotton, 　 is used to calculate 　 position of 　 tool, 　 agreement 　 position, 　 position of 　 floor, 　 position of 　 household 　 and 　 of room

When the operator registers the 　consent 　 reference point of the 　 building structure 　 with a separate 　 program 　 1 　 using the input window provided 　 and stores it in the system,

This is used to calculate the 　 position of each 　 building, the 　 location of the 　 floor included in the same 　 building, the 　 location of the 　 household, and the 　 location of the 　 room.

When an operator registers the 　 reference point of the 　 floor of the 　 building 　 as a separate 　 program 　 1 　 using the provided 　 input window and stores it in the 　 system 　,

This is used to calculate the 　 position of each 　 floor, the 　 location of the household belonging to the 　 floor, and the 　 position of the 　 room.

The worker registers the 　 reference point of the 　 household 　 with a separate 　 program 　 using the input window provided 　 and saves it in the system

Cotton, 　 is used to calculate 　position of 　of each 　 household and 　 of the room. Of course 　2D 　Graphics 　On the drawing 　According to the 　property 　Horizontal 　

It is natural that the 　 range of the value 　 level 　 can be adjusted 　 elastically 　.

[S30　 step]

The 　 s30 　 step is 　 in detail 　 two-dimensional 　 CAD drawing 　 　 object is 　 using a separate 　 program 　 is specified 　 step (s31) 　 and 　

In the object 　 object characteristic information 　 on the system 　 input 　 and 　 stored in 　 step (s32) is made.

The s31 　 step is 　 the worker selects 　 on a certain 　 hierarchical space 　 level 　 for example 　 on a specific 　 floor 　 about a plane 　 two-dimensional 　 graphic drawings

In other words, it is the step of 　 configuring each floor and designating 　 where 　 is 　 and 　 designating 　 objects according to the work target 　. In Fig. 4c,

A specific 　 floor is 　 displayed on a 　 monitor on the system, and a specific 　 floor is 　 configured, and there is a storage, 　 library, 　conference 　1 and 　2　,

office, 　locker, 　shower 　room　, etc.)

(These 　 divisions 　 are already 　 　 two-dimensional 　 graphics 　 on drawings 　, and these 　 configurations are made by 　 in a separate 　 program. 　 That is,

Workers know that 　each 　 room 　 border is divided into 　 angle 　 room 　 boundary line (a kind of 　 demarcation line) on the graphic drawing 　 two-dimensional 　.

Classification work is 　the operator can 　 modify 　 and 　 by such 　 revising work 　 dividing 　 each 　 　 　 revised 　 boundary line 　 each 　 expressing 　 secondary

　 is saved in the one CAD drawing, and 　 is created 　 for 　 deriving 　 details of each 　 room 　 and 　 these 　 works are 　 shown 　 Figure 4d

All.)

　Name of each 　 room (storage, 　library, 　conference 　1 and 　2　, 　office, 　locker, 　shower 　room　) 　 and 　 room 　 number (a0001, 　a0002　, etc.)

Like 4e and 　, 　 by a separate 　 program 　 by using 　 input window provided 　, and 　 in the previous 　 steps (s10, s20) 　 already 　 hierarchical spatial definition

Since there is 　 and 　 location information 　 registered 　 these 　 information can also be checked in 　 above 　 Figure 4e 　. Of course 　 depends on the 　 object selected by the operator 　

The contents are subject to change. If the 　 worker chooses 　 2D 　 CAD 　 drawings 　 related to 　 civil engineering work 　 　 specific 　 　 for 　 civil engineering work 　

　 2D 　 CAD 　 drawings 　 etc. 　 will be displayed 　 and 　 the operator 　 wants 　 　 designated 　 after, 　 that 　 designated 　 objects 　

It is natural that 　 can be registered 　 using the 　 input window provided by a separate 　 program 　.

s32 　 step is 　specified 　for each 　 room 　 according to the construction type (e.g. 　 finishing type) 　 specific 　 in the specified 　 state, 　 floor, 　 mop, 　 wall, 　 cloth

This is the step of registering 　 characteristic information, 　 namely 　 object characteristic information for 　 parts such as 　, 　 molding 　 and 　 curtain box.

These 　object characteristic information 　by a separate 　 program 　 provided in the 　 input window 　 the operator 　 input 　 　 this is shown

Fig. 4f. In Figure 4f, 　1 building 　 2 stories above ground 　locker 　room 　 is designated 　, and 　 for the above 　locker 　room 　 details 　 That is,

The floor, 　 mop, 　 wall, 　 ceiling, 　 molding 　 and 　 curtain box 　 can be selected 　 　, and 　 about this 　 worker 　 floor 　 vertical position, 　 mop 　 height

Enter this, 　 wall 　 vertical position, 　 molding 　 vertical position 　, 　 molding 　 width, 　 molding 　 thickness, 　 curtain box 　 vertical position, 　 curtain box 　 width 　 and 　 curtain 　 box 　 depth 　

All. Of course, if 　each 　 is made up of 　 separate 　 detail 　, you can enter 　 separately 　, and 　 the worker should 　 each 　

If you need additional 　 information 　 　 for this 　 you can also enter 　 separately 　 　 will do.

[s40　 step]

Step 　s40 above is 　2D 　 graphic 　 drawing 　 　 object on 　 hierarchical spatial information 　 and object property information 　 using a separate 　 program 　 combining

Is the 　 step. In other words, the 　 operator selects 　2D 　 graphics 　 drawings 　 certain 　 objects (specific 　 buildings, 　 specific 　 floors, 　 specific 　 rooms 　 specific government committee)

If you choose 　, as mentioned above, 　 hierarchical spatial information, 　 location information, and 　 object characteristic information are already 　 registered, 　 stored 　 because it is the 　 step, so 　 all 　

There is a need to connect each other so that the sieves and the above information can be connected to each other so that they can be used. Of course 　 these 　 work 　 the operator 　

It is not 　 to do 　 but it is done on the system 　 by a separate 　 program 　1.

Thus, 　 on the system 　 the operator 　 can check 　 can 　 　 related to the building structure 　 all 　 two-dimensional 　 graphic drawings 　 　 objects on the 　 worker 　 registered

It is connected with one 　 all 　 information 　 whether the operator 　 selects any 　 two-dimensional 　 graphic 　 　 object on the drawing 　 reminder 　 object 　 all 　 information

The included 　 state becomes 　. Specifically, if the 　 worker selects 　 code of 　 specific 　 room 　 on 　 system 　 and executes 　

The 　2D 　graphic drawing 　corresponds to the 　real code 　the object characteristic information of the 　 is connected 　 through the process 　, this is the 　 to be described later

Nominal 　 logical 　 three-dimensional 　 data will be created 　 number 　 　 base 　 will be prepared.

[s50　 step]

The above step 　s50 is 　 hierarchical spatial information 　 and 　 object characteristic information included 　 two-dimensional 　 graphic 　 drawing 　 for 　 object 　 surface shape information 　 separate 　

　 step (s51, 　 23 in Fig. 2) 　 and 　 above 　 location information 　 included 　 logical 　 three-dimensional 　 data 　 generated by 　 in program 1

(s52, 　 　 24 in Fig. 2) 　, 　 s50 　 step 　 previous 　 steps 　 two-dimensional 　 graphic 　 　 angle 　 objects and 　 operator 　 input 　 various information

This is the step in which the 　2D 　 drawing becomes 　3D in the 　 connected 　 state.

To convert a two-dimensional 　 graphic 　 　 object into 　 three dimensional 　 shape 　, 　Once at a specific 　 reference point, the relative 　horizontal, 　vertical position of the object

　 must be set, and 　to display 　 thickness of object 　 　 thickness information 　 etc 　 pre-set 　 　 bar, 　 these 　 setting values are described above

In one 　 s 50 　 step 　 previous 　 step 　 　 is registered 　 in the system 　 　 is stored 　, 　 is combined in the 　 two-dimensional 　 part selected by the operator 　

It can be changed to three-dimensional 　 shape.

Specifically, 　explained, 　specific 　 　 specific 　 　 constituting 　 each 　 part 　 shape is 　 in case of finishing work 　 floor, 　 mop, 　 wall, 　 ceiling 　 and 　 curtain

It is composed of boxes, etc. Since each 　 part is composed of 　 in a certain 　 side, there will be 　, so the 　 shape of the 　 position of each 　 part is 　 part of a specific room

The arc position is 　 relative to 　 (depending on the location information), and the shape of the 　 face is determined by 　 object characteristic information.

In this 　invention, the result of 　 about the 　 position 　 and 　 shape of these 　 surfaces is referred to as 　 surface 　 shape information 23a.

Explaining the above 　surface shape information 　final construction 　 part 　 middle 　 floor 　 as an example 　 floor 　 in step 　 　 specified above 　 　 　 angle of demarcation line 　 left

Using the table values, the 　 shape of the floor surface is formed, and the 　 vertical position of the floor 　 value is used to determine the height of the floor 　.

Information is created,

In the case of 　, use the 　 angle 　 coordinate of the thread 　 demarcation line 　 the mop 　 vertical surface 　 the bottom coordinate 　, and use the mop 　 height 　

The upper coordinate is determined (e.g., if the coordinate value of a specific 　 room is composed of 　P1, P2, P3, P4 　, and the height of the mop 　 is 　H

The 　 coordinate of the 　 vertical surface is 　(P1,P2,P1+H,P2+H),　(P2,P3,P2+H,P3+H),　(P3,P4,P3+H,P4+H),(P4 ,P1,P4+H,P1+H)

　Above 　PA, P2, P3, P4 is 　X, Y axis 　 value in 　 coordinate axis 　, 　H　 value is 　Z axis value 　 is set

Surface shape information is created,

In the case of the wall 　, the 　 coordinate value of the room 　 demarcation line is used as the 　 wall surface 　 bottom coordinate, and the 　 top end of the wall 　 height 　 the ceiling height 　 in the bottom coordinate 　 the top coordinate of the wall

If the table value is added and the 　 height of the wall is 　 generated, and the vertical position of the wall is 　 input 　, in the case of the 　 composing the wall 　 in the coordinates 　 Z axis 　 value 　 wall 　 vertical position

　The 　 value is added to the 　, and the 　 shape coordinate of the wall is created 　, and finally, the 　 surface shape information of the wall is created.

For the ceiling, the 　 coordinate value of the 　 front 　 shape 　 is created by using the 　 coordinate of the 　 room 　, and the 　 surface shape information for the 　 ceiling is created.

Molding uses the 　 vertical position 　 and 　 width of the 　 to the 　 coordinate value of the 　 thread 　 and the 　 surface shape information of the molding is created.

For curtain box, use the 　window 　 sign 　 curtain box 　 existence/nothing 　 specified 　 　 the coordinates of the window sign, 　 the dimension of the window, 　 the curtain box 　 vertical position 　 and the width 　

　The shape information of the surface of the curtain box is created.

The above-described 　each 　 surface shape information is 　 generated by 　 in a separate 　 program on the 　 system, and 　 is stored separately. At this time, all 　 face shape information is 　

There is no need to be saved. An architectural structure is composed of 　a number of 　objects 　, and 　 it stores 　 surface shape information about these 　 objects 　 in advance 　

Because 　delays 　operation speed of the system 　delays 　results 　for 　objects 　 and 　 objects that the operator selects 　 and related 　 objects

It is desirable that the surface shape information is 　 saved.

These 　 surface shape information 　 includes 　 hierarchical spatial information, 　 location information 　, and object characteristic information (23b, 　 stored and registered 　 and 　 classified) 　.

In Myung, 　 is called 　logical 　 three-dimensional 　 data. This is distinguished from 　physical 　 three-dimensional 　 data and 　 which will be described later, but the difference is 　 above 　 logical 　 3rd order

Each 　 object has 　 all 　 coordinate values 　 absolute 　 reference coordinates 　 does not support 　 and several 　 reference coordinates 　 centered on the original 　 data

There is. In other words, the 　above 　 logical 　 three-dimensional 　 data 　 absolute 　 reference value 　 　 position 　 etc. 　 not fixed 　 not 　 in the 　 operator's selection

　 　 various 　 connected 　 present 　 　 can be 　 　 the advantage 　 will be. This 　 logical 　 three-dimensional 　 data 　 is created 　 steps 　

This is the stage 52.

There are times when it is difficult to shape all of the logical 　 3 dimensional 　 data 　 two dimensional data 　 to the original 　 shape 　 3 dimensional 　 shape. this

At times, the operator can add or modify the shape of the part of the object.　 hierarchical spatial information about 　 objects that need to be modified 　 or 　 added

The location information 　 and 　 object characteristic information is 　 registered/saved by the 　 operator input 　 using a separate 　 program. These 　 steps 　 required

In one 　 case 　 　 can occur 　 　, so 　 additional/subsidiary stages 　 will be 　, and this is called 　s53　 step in this 　 invention.

[S60　 step]

The above 　s60　 step is 　 logical 　 three-dimensional 　 data 　 absolute 　 standard 　 coordinate values 　 based 　 three-dimensional 　 data 　 change 　 of the building structure

This is the step of creating an image. Due to these 　work 　　Apartments and 　Same 　Architectural structures 　Specific 　 Buildings/Floors 　 2D 　 CAD 　 Drawings 　 3D

　 shown 　 state 　 　 is also 4g.

Unlike the 　 logical 　 three-dimensional 　 data created in the s52 　 step 　 the physical 　 three dimensional 　 data is 　 the graphic 　 constituting the 　 all 　 coordinate values 　 one clause

It is 　 relative to the 　 coordinates 　, so the operator 　 in the same 　 output device as a monitor 　 two-dimensional 　 CAD 　 drawing 　 three-dimensional shape

can confirm.

When explaining the specific 　 conversion steps 　 for the case of a building structure 　, from 　 hierarchical spatial information 　 and 　 location information 　 specific 　 building/floor 　 by floor 　 vertical position
