Description

  The present invention relates to a CAD system used for building design.

Conventionally, a CAD (Computer Aided Design) system has been introduced for building design (see, for example, Patent Document 1).
The CAD system described in Patent Document 1 includes a basic design system that performs basic design and peripheral support at that stage, and this basic design system includes a design design subsystem, an integration subsystem, and a business subsystem. The design design subsystem creates a drawing showing the contents of the basic design, and the integration subsystem creates an integration list showing a list of parts to be used, etc. based on this drawing. The business subsystem creates a purchase order and a price estimate for building construction based on the drawings created by the design design subsystem and the contents of the accumulation list created by the accumulation subsystem.

Japanese Patent No. 3738050

Incidentally, in the initial stage of basic design, the arrangement of various parts is often not decided, and in such a situation, the design design subsystem drawing is often incomplete.
However, in the CAD system described in Patent Document 1, the components cannot be integrated by the integration subsystem unless various components are arranged on the drawing in the design design subsystem, that is, in a completed state. For this reason, it takes time and effort for the design work to obtain accurate integration information. Further, there is a problem that if the parts that should be originally arranged are not arranged in the drawing, the omission of integration occurs and accurate integration information cannot be obtained.

  An object of the present invention is to provide a CAD system that can acquire integration information including various parts that are not arranged in a design drawing.

  A CAD system according to the present invention is a CAD system used for building design, which includes a storage means for storing parts constituting a building, a drawing generation means for generating a building drawing by arranging the parts on the drawing, and a building. And integrating means for accumulating the components provided to obtain integrated information, wherein the integrating means comprises at least three types of pallets: an input-required component pallet, an unplaceable component pallet, and an integrated component pallet. In the pallet, the parts that are always placed in the building are selectably arranged. In the unplaceable parts pallet, the parts that are normally placed in the building are arranged so as to be selectable together with the quantity. Parts that do not appear are arranged with the quantity, and the quantity per part in the unplaceable parts pallet is the planned placement quantity that will be placed per building, While subtracting the number of the palette in the case of arranging the component on a surface, when the integration is characterized by counting both the number of remaining components on the placed components and the palette to the drawings.

Here, the pallet is a list of parts used in the building, and is classified into an input-required part pallet, an unplaceable parts pallet, and an integrated parts pallet according to the type of part.
According to this invention, the quantity can be input to the parts belonging to the unplaceable parts pallet. The quantity input here is the quantity scheduled to be arranged per building and the quantity of parts not arranged in the drawing. Note that this quantity is decremented when a part belonging to the unplaceable parts pallet is placed in the drawing. When integrating, both the quantity displayed on the unplaceable parts pallet and the quantity arranged on the drawing are reflected.
Therefore, even if the drawing is not completed, the total omission can be prevented, and the trouble of arranging various parts can be omitted, so that the design work can be made more efficient.

  In the CAD system of the present invention, it is preferable that the integrating means modularizes each pallet for each building specification or design condition and stores it in the storage means, and reads each pallet modularized at the time of design.

According to the present invention, the integration means reads each modularized pallet registered in the storage means, so that each pallet according to the building specifications and design conditions can be used as an initial value.
Therefore, since the design can be started with each read pallet as an initial value, it is possible to design in a short time and to create a more accurate estimate.

  The CAD system of the present invention preferably includes pallet creating means for reading each part from a completed drawing to create each pallet and storing the created pallet in the storage means as an initial value.

  According to the present invention, it is possible to create various pallets for building use and design conditions only by reading parts using existing drawings. Since each pallet is modularized and stored in the storage means, when starting a new design, it is only necessary to read the pallet corresponding to the specifications and design conditions of the building to be designed and place the parts on the drawing. Therefore, the efficiency of design work can be improved.

  In the CAD system of the present invention, a list of accumulated information acquired by the accumulating means is created, and among the parts items of the list, for parts that are of an unplaceable parts pallet and are not arranged in the drawing It is preferable to provide integrated information display means for displaying a non-arranged flag.

In the present invention, among the accumulated parts, a non-placement flag is displayed for unplaced parts that belong to the unplaceable parts palette, so it is possible to check at a glance which parts are unplaced. Can do.
Therefore, unplaced parts can be confirmed immediately, and the progress of design can be easily grasped. In addition, when designing next time, it is only necessary to arrange the part on which the non-arrangement flag is displayed in the drawing, so that the design can proceed efficiently.

  In the CAD system of the present invention, it is preferable that the CAD system includes an estimation unit that acquires estimation information based on the integration information.

Since the estimated quantity of parts used per building is integrated in the integration information, a more accurate estimate can be created even if the drawing is not completed.
Therefore, a more accurate estimate can be presented to the owner from an early stage of the design.

  In the CAD system of the present invention, it is preferable that the CAD system further includes a part information updating unit that updates part information of the part in the storage unit.

In the present invention, the component information in the storage means can be updated. For example, if a part that has been discontinued is updated, the information is displayed when the part is used on a pallet.
Therefore, since the component information can be grasped quickly at the design stage, the design can be performed efficiently.

The pull-down menu 90 includes a palette copy (essential) command 91 and a palette copy (unallocated) command 92.
When the palette copy (essential) command 91 is selected, the selected component 111 is added to the input mandatory component palette 71.
When the palette copy (unplaced) command 92 is selected, the selected component 111 is added to the unplaceable component palette 72.
Note that the components belonging to the integration component pallet 73 are not arranged in the drawing, so the integration components are added as appropriate in the pallet tool 70.

The input essential component pallet 71, the unplaceable component pallet 72, and the accumulated component pallet 73 created in this way are modularized for each building specification and design condition and stored in the storage device 51.
Specifically, the file menu 751 includes a registration command for registering a pallet in the storage device 51 and a read command for reading a pallet registered in the storage device 51. Then, each modularized pallet is stored in the storage device 51 by the registration command. Each stored pallet can be read and edited when designing similar building specifications and design conditions in the future. At that time, the pallet stored in the storage device 51 can be read by the read command.

[2. Configuration of production preparation system 12]

This production preparation system 12 is operated by a production designer 15 to concretely develop the contents of the basic design information 11A, a detailed part drawing of individual parts necessary for factory production, etc., an assembly drawing showing its assembly, A process diagram relating to production and construction (manual including instruction of work and illustration of a state during work) and the like are created as production design information 12A.
Then, a part purchase order created based on the production design information 12A and an integration list in which information on the corresponding part is described are output.

[3. Effects of this embodiment]
The embodiment described above has the following effects.
(1) The accumulating means 22 can input the number of parts not arranged in the drawing in the unplaceable parts palette 72. Since both the number of parts displayed in the list on the unplaceable parts pallet 72 and the quantity of parts arranged in the drawing are integrated, it can be integrated more accurately without completing the drawing. .
Therefore, it is not necessary to create a detailed drawing in the initial stage of the design, and it is possible to easily create an estimate in a short time without omission. That is, a more accurate estimate can be presented to the client 13 from the initial stage of design.
And since it is not necessary to complete a drawing at an initial stage, it is not necessary to spend time for the subsequent change work. That is, the efficiency of design work can be improved.

Further, in the pallet tool 70 of the integrating means 22, when a part belonging to the unplaceable parts palette 72 is placed in the drawing by the placement button 774, the quantity input to the unplaceable parts palette 72 is subtracted. On the other hand, when a part in the drawing is added to the unplaceable parts palette 72, a new part is added to the list 74 of the unplaceable parts palette 72. If the same part has already been registered, add the quantity.
Therefore, the parts on the unplaceable parts pallet 72 can be more accurately integrated because the quantity arranged in the drawing is synchronized with the quantity not arranged.

(2) Each pallet created by the integrating means 22 is modularized for each building specification or design condition and stored in the storage device 51. Therefore, when designing a building with similar specifications or design conditions in the future, The pallet can be read from the storage device 51.
Therefore, since the design can be started based on the read pallet, the design can be performed in a short time, and the efficiency of the design work can be improved.

(3) Since the palette creating means 23 can create each palette from the drawings, the integrating means 22 can be applied to the drawings created so far.
Therefore, it is possible to accumulate more accurately with respect to existing drawings, and it is possible to create a more accurate estimate.
In addition, since each pallet created by the integrating means 22 is modularized for each building specification and design condition and stored in the storage device 51, it is already registered when designing a pallet having a similar building specification or design condition in the future. Each pallet can be read and reused. Therefore, the design work can be performed efficiently.

(4) In the integration list created by the integration information display means 31, an unplaced flag is displayed for components that belong to the unplaceable component palette 72 and are not placed in the drawing. It can be confirmed at a glance whether it is an arrangement.
Therefore, it is possible to immediately confirm how many parts have not been arranged, and it is possible to easily grasp the progress of the design. In addition, when designing next time, it is only necessary to arrange the part on which the non-arrangement flag is displayed in the drawing, so that the design can proceed efficiently.

(5) Parts not arranged in the drawing are integrated in the estimate created by the estimation unit 41.
Therefore, since a more accurate estimate can be presented to the owner even at an early stage of the design stage, the future design can proceed smoothly.

(6) The parts information stored in the storage device 51 can be updated by the parts information updating means 60. In addition, component information is displayed on each pallet of the pallet tool 70 which is the integrating means 22.
Therefore, since the latest part information can be referred to by the integrating means 22, the design can be advanced efficiently.

  It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.

  The present invention can be used in a CAD system used for building design.
