Description

Technology Field

[0001] The present invention relates to the generation of 3D installation drawings required for the installation of outfitting equipment for a ship or plant, and specifically to a system and method that can easily and efficiently generate 3D installation drawings for the installation of outfitting equipment for a ship or plant by utilizing a 3D model viewer. Background Technology

[0002] Installation drawings for outfitting equipment in the shipbuilding and plant sectors are generally created using orthographic projection, which represents the object on a two-dimensional plane by projecting a three-dimensional object at a right angle. Each item of outfitting and the overall installation drawings consist of a plan view, elevation view, section view, and detail view, and in some cases, axonometric projections such as an isometric view are added to aid the user's understanding.

[0003] CAD programs are currently widely used to create Cartesian coordinate maps and axonometric projections, but creating axonometric projections is particularly time-consuming. This is because CAD programs require rotating the axis of rotation by inputting the rotation angle numerically; therefore, while it is necessary to find an appropriate angle that can accurately represent installation information for each view, finding such an angle is not easy. Additionally, since it is necessary to delete hidden lines from the rotated model, further modification work is required. The problem to be solved

[0004] As mentioned above, there are many difficulties in creating axonometric projections, which are 3D installation drawings, using CAD programs. Therefore, a 3D model viewer was introduced to quickly convert and display design drawings created with CAD into 3D, thereby improving the efficiency of design review in the shipbuilding and plant sectors.

[0005] However, operating the 3D model viewer is required to check dimension information or material numbers; checking installation information through the model viewer at the production site required excessive operation time, and accurate operation was difficult due to limitations in the size and interface of mobile devices such as tablets. means of solving the problem

[0006] According to one aspect of the present invention for solving the above-mentioned problem, a method for generating a 3D installation drawing for shipbuilding and marine applications is provided, comprising loading a 3D model of a ship plant, adding installation information for outfitting items to the 3D model, drawing necessary parts of the 3D model, and adding detailed information for the installation of outfitting items.

[0007] Preferably, if there are parts of a 3D model where it is difficult to add installation information, the method further includes individually editing the images of those parts, adding installation information of the equipment included therein, creating drawings, and adding detailed information for the installation of the equipment.

[0008] According to another aspect of the present invention, a 3D model inquiry and installation information generation unit (10) that loads a 3D model of a ship plant, arranges the 3D model in an axonometric projection of an appropriate angle, and adds installation information of necessary outfitting items; and

[0009] A 3D installation drawing generation system for shipbuilding and marine applications is provided, comprising: a 3D installation drawing generation unit (20) that draws the necessary parts of the 3D model generated in the above 3D model inquiry and installation information generation unit (10).

[0010] Preferably, a 3D installation drawing generation system for shipbuilding and marine applications is provided, further comprising a 3D installation drawing auxiliary generation unit (30) that individually edits images of parts of a 3D model that are difficult to express by the 3D model inquiry and installation information generation unit (10) and the 3D installation drawing generation unit (20), and adds installation information of the equipment included therein.

[0011] Preferably, the 3D installation drawing generation unit (20) provides a 3D installation drawing generation system for shipbuilding and marine applications, characterized in that it can add detailed information to each of one or more axonometric projections of a 3D model.

[0012] Preferably, the 3D installation drawing generation unit (20) is characterized by being able to add detailed information to each 3D installation drawing generated by the 3D installation drawing auxiliary generation unit (30), thereby providing a 3D installation drawing generation system for shipbuilding and marine applications. Effects of the invention

[0013] According to the present invention, even a designer with little experience can easily create installation drawings by using a 3D model viewer program that is easier to learn than a CAD program.

[0014] It takes less time to create a 3D installation drawing than to create a 3D installation drawing using the conventional 2D Cartesian coordinate system and the axonometric projection method.

[0015] In addition, by representing the object in three dimensions, the content of the drawing can be intuitively grasped, and installation drawings for various fixtures using axonometric projection can be created quickly and efficiently.

[0016] In addition, the 3D installation drawing generated according to the present invention does not require as high a level of proficiency as when interpreting a general installation drawing of an equipment created using an orthogonal coordinate system, reduces the difficulty of reading, and reduces the occurrence of rework due to misreading and the number of simple inquiries about the drawing, thereby increasing the work efficiency of the installation worker and the office productivity of the drawing creator.

[0018] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0019] The terms used herein are merely for describing specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “comprising” or “having” are intended to indicate the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0020] Additionally, terms such as “…part,” “…unit,” “…module,” and “…device” described in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software.

[0022] Hereinafter, with reference to FIG. 1, we will examine a 3D installation drawing generation system for shipbuilding and marine applications according to one embodiment of the present invention.

[0023] The 3D installation drawing generation system for shipbuilding and marine applications according to the present invention may include a 3D model inquiry and installation information generation unit (10) and a 3D installation drawing generation unit (20). Additionally, it may further include a 3D installation drawing auxiliary generation unit (30).

[0024] The 3D model inquiry and installation information generation unit (10) can load a 3D model of a ship plant, place the 3D model in an axonometric projection at an appropriate angle, and add installation information such as material numbers, dimensions, and instructions for the necessary outfitting items. The 3D model inquiry and installation information generation unit (10) is a 3D model viewer program. It is a 3D model viewer that has functions such as measuring dimensions and writing notes to be suitable for creating a 3D installation drawing. It can load a 3D model created in the 3D model generation unit and display it on a display, and display installation information including material information such as installation dimensions, material numbers (Tag no.), and instructions on the 3D model.

[0025] At this time, the 3D model file can be generated in the 3D model generation unit, and specifically, a CAD program for 3D modeling from Aveva Marine, which is widely used in the shipbuilding plant industry, can be used. In addition, the generated 3D model file can be stored in a 3D model database (DB) for each project, and the 3D model inquiry and installation information generation unit (10) can load the 3D model from the 3D model database (DB).

[0026] The 3D installation drawing generation unit (20) can create a drawing of a 3D model by placing a necessary part of the 3D model generated by the 3D model inquiry and installation information generation unit (10) as an axonometric projection at an appropriate angle, capturing an image with installation information noted thereon, modifying or saving it, and automatically placing the saved drawing into a drawing template.

[0027] The 3D installation drawing auxiliary generation unit (30) can edit images of parts of the 3D model that are difficult to express by the 3D model inquiry and installation information generation unit (10), and can add installation information for each piece of equipment included therein. Specifically, parts that cannot be expressed because there is no function in the 3D model viewer program, or parts that are inconvenient or difficult to express due to the function of the 3D model viewer program, can be created by using Microsoft's PowerPoint or other CAD programs. For example, an Overview page that creates a Key Plan, ISO View, and material list on one screen is difficult to create using only the functions of the 3D model viewer program, so it is created by editing necessary images and adding tables in PowerPoint, and content such as display and dimensioning standards and Typical Detail can also be created in PowerPoint or CAD and then captured as an image for use.

[0028] The 3D installation drawing generation unit (20) is an add-in program of a 3D model viewer that captures a screen containing material information and installation information generated by the 3D model inquiry and installation information generation unit (10) and the 3D installation drawing auxiliary generation unit, and edits the captured image. It can add detailed information to one or more axonometric projections of the 3D model and can add detailed information to the 3D installation drawing generated by the 3D installation drawing auxiliary generation unit (30). The 3D installation drawing generation unit (20) can place the captured image on a designated template to create an installation drawing as a PDF file, or save the captured image as is to a server. Through this function, the drawing of an installation drawing using the 3D model viewer is realized, and the time required to create a 3D installation drawing can be reduced as there is no need to transfer the captured image to another program for editing.

[0029] Conventionally, in order to create a 3D installation drawing with added detailed information for the installation of an equipment, captured images were transferred to PowerPoint to create the drawing. However, creating a single Detail View required at least 15 editing processes (copying and pasting the main image, resizing, positioning, and ordering between multiple images; and copying and pasting, resizing, positioning, and ordering of orientation indicators, etc.). But by using the 3D installation drawing generation unit according to the present invention, detailed information can be added simply and quickly by utilizing the function of adding information to be entered in the Detail View.

[0030] Referring to Fig. 2, it shows a page for recording general installation guides and instructions, such as General Note and Typical Detail. Content created in PowerPoint or CAD can be captured and registered as an image file in the 3D installation drawing generation section.

[0031] Referring to FIGS. 3 and 6, there is an example of a 3D installation diagram configuration. FIG. 3 shows an Overview page, and FIG. 6 shows a Detail view page. According to the present invention, one can view the drawings by moving between pages, just as one zooms in and out in a 3D model viewer.

[0032] The Overview page displays the overall scope and volume of the installation work and is generated in the 3D model inquiry and installation information generation unit (10). If necessary, secondary processing may be performed using a PowerPoint program. The generated Overview page is captured and registered as an image file in the 3D installation drawing generation unit (20).

[0033] The Detail view page contains installation information for the equipment to be installed, and unlike existing drawings where the installation location and direction of the equipment are found by referring to Longi., frame number, and Elevation or Grid number, the installation location and direction can be found intuitively using the shape information of the surrounding structure, and the drawing is configured so that all information necessary for installation can be identified in a single Detail view.

[0034] Referring to FIG. 4, Area Plan or Area Division indicates that when creating a 3D installation drawing, there may be parts that are difficult to show in the drawing because they are obscured by other structures, so the installation area is appropriately divided to create the drawing, and this page is created to provide information on the divided area. After capturing the 3D model in the form of a plan view in the 3D model inquiry and installation information generation unit (10), secondary processing is performed to display the Area Boundary using PowerPoint. The content created through secondary processing is captured and registered as an image file in the 3D installation drawing generation unit (20).

[0035] Referring to FIG. 5, an overview by Area is shown, and an overview and material list are created for each Area previously separated. At this time, Detail view numbers can be assigned and displayed. After capturing the 3D model in the 3D model inquiry and installation information generation unit (10), a secondary processing is performed to display the Detail view numbers in PowerPoint and create a material list. The content created through the secondary processing is captured and registered as an image file in the 3D installation drawing generation unit (20).

[0036] Referring to FIG. 6, the Detail view page contains installation information for the equipment to be installed. It can be created in the order assigned in the Area-specific Overview created earlier. Dimensions, material numbers (Tag no.), instructions, etc., can be entered on the 3D model imported from the 3D model inquiry and installation information generation unit (10). Once the installation information is entered, the capture function in the 3D installation drawing generation unit (20) is executed to capture the Detail view. At this time, not only the annotation (note) containing the structure and installation information of the equipment to be installed, but also the orientation indicator box indicating the observation position and direction and the 3D model are captured together and automatically placed on a designated template to be saved as an image file.

[0037] Referring to Fig. 7, this is a 3D model of the previously described compass box. There are Ship Type (PORT-STBD-FWD-AFT-TOP-BTM) and Topside Type (NORTH-SOUTH-EAST-WEST-TOP-BTM). When the 3D installation drawing generation unit is executed to create a 3D installation drawing, the compass box type can be selected.

[0038] Referring to Fig. 8, the 3D model inquiry and installation information generation unit and the 3D installation drawing generation unit are displayed on a single screen. The 3D model inquiry and installation information generation unit is a 3D model viewer program that has enhanced functions for recording dimensions and notes to make it suitable for creating 3D installation drawings. In the 3D model inquiry and installation information generation unit, a 3D model can be loaded, rotated to an appropriate orientation for displaying installation information, and then the installation dimensions, material number, and installation instructions can be displayed. The 3D installation drawing generation unit is an add-in program of the 3D model viewer that is responsible for the functions of saving, editing, and distributing 3D installation drawings.

[0039] Referring to Fig. 9, only the 3D model viewer add-in program corresponding to the 3D installation drawing generation section is displayed. At the top of the program, you can select the Project, Installation and Work Time (Stage), Installation Work Location (Block no.), Discipline, Item, and Area. After selecting the area for which you want to create a drawing, you can create a 3D installation drawing for that area by pressing the Edit button. Once the Detail view creation is complete in the 3D Model Inquiry and Installation Information Generation section, you can capture an image using the Add button. Incorrectly captured images can be deleted using the Delete button. Pressing the Save Work (PC) button saves the work content to the local disk. You can open the 3D installation drawing file saved on the local disk via Open Work (PC). Whenever a Detail view is added, it can be automatically numbered using a combination of the Area number and a serial number (Area A is A1, A2, A3, …, and Area B is B1, B2, B3, …). If you double-click the Detail view image... You can edit (mark up) the saved Detail view images. In the Image Information tab, you can save the General Note, Typical Detail, Overview, Area Plan, or Area Division and Area Overview images described earlier. Once the 3D installation drawing is completed, you can save the created drawing to the 3D installation drawing image database via the Save (Server) button. After reviewing the drawing and receiving approval for issuance, you can distribute the 3D installation drawing by pressing the Mobile Distribution or Full Area Distribution buttons. Once distributed to mobile, the 3D installation drawing can be viewed using a dedicated 3D installation drawing viewing application.

[0041] Below, we will examine the method for generating a 3D installation drawing for shipbuilding and marine applications according to the present embodiment.

[0042] The method for generating a 3D installation drawing for shipbuilding and marine according to the present invention may include loading a 3D model of a ship plant, adding installation information for outfitting items to the 3D model, drawing necessary parts of the 3D model, and adding detailed information for the installation of outfitting items.

[0043] At this time, if there are parts of the 3D model where it is difficult to add installation information, the image of that part may be individually edited to add installation information of the included fixtures, to create drawings, and to add detailed information for the installation of the fixtures.

[0044] The aforementioned method for generating 3D installation drawings for shipbuilding and marine applications may also be implemented in the form of a recording medium containing computer-executable instructions, such as applications or program modules executed by a computer. A computer-readable medium may be any available medium accessible by a computer and includes both volatile and non-volatile media, as well as removable and inseparable media. Additionally, a computer-readable medium may include a computer storage medium. A computer storage medium includes both volatile and non-volatile, removable and inseparable media implemented by any method or technique for storing information, such as computer-readable instructions, data structures, program modules, or other data.

[0045] The above-described method for generating a 3D installation drawing for shipbuilding and marine applications may be executed by an application that is basically installed on a terminal (which may include a program included in a platform or operating system installed on the terminal by default), or by an application (i.e., a program) that is directly installed on a master terminal by a user through an application provider server, such as an application store server, an application, or a web server related to the service. In this sense, the above-described method for generating a 3D installation drawing for shipbuilding and marine applications may be implemented as an application (i.e., a program) that is basically installed on a terminal or directly installed by a user, and may be recorded on a computer-readable recording medium such as a terminal.
