Description

Apparatus and method for automatic drafting isometric drawings, spool drawings and bill of material used in piping design}

The present invention relates to isometric and spool drawings and bill of materials used in piping design, and more particularly, in piping design, specifications, frequently used drawings by ordering companies, drawings of various blocks, application codes, etc. An apparatus and method for automatically creating isometric drawings, spool drawings, and bills of materials by simply storing object data in memory so that they can be run back in a CAD program in advance.

In general, piping design is essential for industrial plant and shipbuilding design, and isometric drawing, spool drawing and bill of material (BOM) are essential for piping design.

Here, the isometric drawing is a drawing which is shown by extracting one line or a predetermined unit from all the pipes, and usually one construction includes about 200-3000 isometric drawings. The spool drawing is a 4-5 equalized drawing that makes the isometric drawing easy to actually work with. Typically, one isometric drawing is divided into 4-5 spool drawings. On the other hand, the bill of materials is a chart showing the size, length, number, etc. of the various materials (flanges, valves, gaskets, etc.) in the drawings, and is usually displayed on the upper right of the isometric drawing.

Conventionally, the isometric drawing, spool drawing, and the preparation of the bill of materials are usually performed in the following order.

First, when the overall piping layout is created, the senior technician views and prepares the isometric drawings, spool drawings, and bill of materials by hand in separate forms. After the manual work, a junior technician rewrites it using a computer aided design (CAD) program. Subsequently, the supervisor reviews the drawings made in CAD and the like, and this process is repeated at least three times until the work is completed.

Therefore, such a conventional drawing creation method has a problem in that the work is clearly distinguished between the senior technician and the CAD worker and cannot share work with each other.

In addition, when the bill of materials is manually created, it takes a lot of time to create, and frequently a typo of a CAD worker occurs. As a result, there is a problem that a large amount of time is required because several times of review is required.

In order to solve the above problems, an object of the present invention is to store object data such as specifications, order form for each company, drawings of various blocks, application codes, etc., which are frequently used in piping design, in memory so that they can be returned in advance in a CAD program. In addition, the user provides an apparatus for automatically creating an isometric drawing, a spool drawing and a bill of material by simply importing the object data.

Another object of the present invention is to provide a method for automatically creating isometric drawings, spool drawings and bills of material in the apparatus.

A method of writing is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an isometric and spool drawing and a bill of material automatic apparatus for use in piping design according to a preferred embodiment of the present invention.

The CAD program storage unit 102 stores the CAD program. This means a general CAD (Computer Aided Design) program.

The memory 106 includes at least isometric, spool, and spool drawings for the piping design, including at least the format to be used for the piping design, drawings of frequently used blocks, application codes, requirements specifications, and vendor-specific drawings. Object data required for billing is stored in a form that can be returned on the CAD program. That is, the memory 106 is to store drawings or data that are frequently used in the field of piping design, which is essential for industrial plant or shipbuilding design, to be executed in advance in the CAD program, that is, linked.

Table 1 shows an example of the object data stored in the memory shown in FIG.

The table 116 stores application codes. Application code means various standards applied to the piping design. The format unit 118 stores special items, order form for each company, and reference data. The specification unit 120 stores various specifications considering characteristics of each construction. The block unit 122 stores the drawings of many and frequently used parts according to the drawings, the specifications, the specifications, the application codes, and the companies. In other words, the drawings that are actually drawn in the drawing design are stored in advance so that they can be linked with the CAD program.

On the other hand, the master file unit 124 stores the finally completed isometric drawing (including the material specification). Files stored in the master file section can be read and referenced or modified at any time, so that file management can be done systematically and efficiently.

Note refers to matters that should be specially emphasized or considered in the drawings (drawing scale, change of company logo, etc.) unlike ordinary matters.

Drawing styles store drawing styles suitable for companies that are in charge of plumbing design work.

The input unit 110 inputs matters necessary for the drawing and bill of materials including the object data.

The main controller 104 combines the object data stored in the memory 106 based on the value input from the input unit 110 to read an isometric drawing of a suitable form. In addition, a bill of materials corresponding to the isometric drawing is created. The CAD program stored in the CAD program storage 102 is called to display the read isometric drawing and the created bill of materials on the CAD program. On the other hand, when the isometric drawing is read, the spool drawing is automatically created based on the read isometric drawing and the created bill of materials and controls to be displayed on the display unit 112. Here, the spool drawing creation is a process of converting it into unit work (dividing the isometric drawing into several pieces) based on the already prepared and drawn isometric drawing and bill of materials data, and thus, it is possible to create and output without additional work.

At this time, the isometric drawing and the bill of material and the spool drawing are linked so that only the isometric drawing is modified so that the spool drawing and the bill of material are immediately modified. This significantly reduces the likelihood of typos compared to modifying each drawing and bill of materials separately.

The display unit 112 displays items input to the input unit 110 and a screen displayed by the main control unit 104. The output unit 114 prints the information displayed on the display unit 112 and outputs it.

The input / output control unit 108 interfaces between the main control unit 108, the input unit 110, the display unit 112, and the output unit 114.

2 is a flow diagram of an isometric and spool drawing and a method of automatically generating a bill of materials used in a piping design according to a preferred embodiment of the present invention.

Select isometric drawing creation on the screen displayed on the display of the device (step 202).

Input data of object (specification, application code, grill block, drawing form per ordering company) (step 204).

Based on the input of the object data, a corresponding drawing, that is, an isometric drawing including a bill of materials, is read (step 206). In other words, the object data is combined to read a suitable isometric drawing.

Display (preview) the CAD program (step 208).

It is determined whether there is a correction input (step 210).

If there is an input of the correction, the user directly corrects the CAD program (step 212). That is, the user views and corrects the screen.

Save the completed isometric drawing (including bill of materials) (step 214).

Automatically construct and save spool drawings based on isometric drawings and bill of materials (step 216).

It is determined whether there is a spool drawing display request (step 218).

If there is a display request, the spool drawing is displayed on the CAD program (step 220).

The present invention is not limited to the above-described embodiments, and of course, modifications can be made by those skilled in the art without departing from the spirit of the present invention. Therefore, the scope of the claims in the present invention will not be defined within the scope of the detailed description, but will be limited to the claims below.

According to the present invention, in piping design, object data, such as frequently used specifications, order form for each company, drawings of various blocks, application codes, and the like are stored in a memory so that they can be returned in advance in a CAD program, and a user can retrieve the object data. By automatically creating isometric drawings, spool drawings and bills of material, they have the following effects:

First, it is possible to work on isometric drawings and spool drawings without difficulty even if they are not familiar with CAD work.

Second, it can eliminate the waiting time between senior technicians and CAD workers and work simultaneously.

Third, when only the isometric drawing is completed, the subsequent spool drawing is automatically output based on the isometric drawing and the bill of materials.

Fourth, since data inputted or modified during isometric drawing is directly linked to the spool drawing, it is possible to reduce the occurrence of a typo generated by separately working on both sides.

Fifth, the completed file can be stored at any time in the master file for reference, so anyone can open it for confirmation and plotting.

Sixth, if there are modifications to the drawings or bill of materials, if you find all the drawings manually and change the initial data values manually, subsequent processes can be automatically modified, and only the modified contents can be automatically output.

Seventh, the above several effects reduce the working time by about 1/5 compared with the case of working by the conventional method.
