DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
A self drawing tool of a computer-implemented automated design, modeling and manufacturing system is disclosed. In the following detailed description of the embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
FIG. 1 is a block diagram of a self drawing tool 100 for a computer-implemented automated design, modeling and manufacturing system, according to one embodiment. The self drawing tool 100 includes a file reader module 102, an element analyzer 104, a self draw module 106, a routing module 108, a standardization module 110, a conflict checker module 112, a coordination drawing generator 114, and an output module 118.
In some embodiments, the self drawing tool 100 of the computer-implemented automated design, modeling and manufacturing system may reside in a computing environment as illustrated in FIGS. 2 and 3. The computing environment includes a single computer, (e.g., a desktop personal computer, a laptop, or a workstation). Alternatively, the self drawing module 100 may be implemented on a network of such computers, in which case the computing environment includes one or more servers and a plurality of computers connected thereto in a conventional fashion via network connections. In these embodiments, the self drawing module 100 enables a user to generate routing mechanical elements in a project and bill of material required for the project.
In an exemplary operation, the user provides a schematic drawing associated with the project to the self drawing tool. The schematic drawing may be stored in a database as a computer readable file. The file reader module 102 accesses the file associated with the schematic drawing from the database and identifies elements in the schematic drawing from the file. For example, the file reader module 102 may determine mechanical systems (e.g., pipes, fittings, ductwork, equipment, etc.) in the schematic drawing by reading the file. Then, the element analyzer 104 analyzes each of the elements to obtain geometrical and connectivity information associated with each of the elements. For example, the element analyzer 104 may determine wall/floor elements and locations where mechanical systems may pass through the wall/floor elements in a schematic drawing.
Accordingly, the self draw module 106 connects to a spatial database 116 having predefined objects (e.g., air-ducts, pipes, wires and other mechanical system objects) and fetches desired ones of the predefined objects from the spatial database 116 based on the geometrical and connectivity information of the elements. Also, the self draw module 106 may consider parametric information inputted by a user by a computer operator or via an optical reader or computer file reader for selecting the predefined objects from the spatial database. Exemplary parametric objects may include structural constraints, heating requirements, ventilation requirements, water requirements, electrical requirements, and occupancy requirements associated with the project.
The routing module 108 then determines clearances between each element and elements in its close proximity by analyzing structural, architectural, and trade elements in close proximity to the each element based on the geometrical and connectivity information of said each element. Accordingly, the routing module 108 connects each element with elements in its close proximity using the connectivity information and routes the elements using the fetched predefined objects. For example, the routing module 108 may resize one or more elements in the schematic drawings based on the clearance information and then route the elements through the wall/floor elements.
Substantially simultaneously, the standardization module 110 applies a set of standards to the routed elements. Once the elements are routed, the conflict checking module 112 checks whether there are any conflicts between the routed elements and structural, architectural and trade elements. In one embodiment, the conflict checking module 112 resolves the conflicts (if found) between the elements and the structural, architectural and trade elements. For example, the conflict checking module 112 resolves conflicts by redirecting the elements in most efficient manner to avoid the conflicts. In another embodiment, the conflict checking module 112 may prompt the user to resolve the conflicts if user intervention is required. For example, the conflict checking module 112 flags any potential conflicts determined in the routed elements and highlights potential conflicts and potential solutions for assisting a user in determining a resolution. The user may select from the potential solutions or may create a different solution.
Finally, the coordination drawing generator 114 generates a coordination drawing of the schematic diagram. The coordination drawing thus generated provides routing information of the elements in the schematic drawing and also bill of materials associated with the schematic drawing. The output module 118 outputs the coordination drawing to a computer implemented manufacturing system or a project management and accounting system. For example, the coordination drawing shows routing of the elements through the wall/floor elements of the schematic drawing which is used for installation of elements in the project. Also, the coordination drawing contains a bill of materials for accounting, cost analysis, project budget, quoting, and CAD manufacture of producible items. The computer implemented manufacturing system may include plasma machines, coil lines, pipe cutting machines, etc.
FIG. 2 illustrates a block diagram of an exemplary network system 200 employing a self drawing module for generating a coordination drawing from a schematic drawing of a project, according to one embodiment. The network system 200 includes database servers 202A-N, application servers 204A-N and a coordination drawing database 206. As illustrated, the spatial database 116 resides in the database servers 202A-N, respectively. Further, the self drawing tool 100 resides in each of the application servers 204A-N. The network system 200 includes client devices 208A-N, client devices 210A-N and client devices 212A-N. For example, each client device may be a workstation, a desktop, and a laptop.
In FIG. 2, each of the application servers 204A-N is coupled to the database servers 202A-N. Also, said each of the application servers 204A-N is coupled to the coordination drawing database 206. Further, the client devices 208A-N, the client devices 210A-N and the client devices 212A-N are coupled to the application server 204A, the application server 204B and the application server 204N, respectively. Also, the client devices 208A-N, the client devices 210A-N and the client devices 212A-N are coupled to the coordination drawing database 206.
In one exemplary implementation, the network system 200 is operable for generating a coordination drawing of a project. For example, consider that, a client device 208A makes a request for a coordination drawing of a project to the application server 204A. In such scenario, the self drawing tool 100 in the application server 204A access a file associated with the schematic drawing from the database server 202A and identifies elements in the schematic drawing. The self drawing tool 100 then obtains geometrical and connectivity information of the elements. Further, the self drawing tool 100 utilizes the geometrical and connectivity information along with parametric objects to select predefined objects from the spatial database 116. Accordingly, the self drawing tool 100 routes the elements through the structural, architectural and trade elements and generates a coordination drawing of the project using the predefined objects. The application server 204A thus stores the coordination drawing in the coordination drawing database 206 as well it is provided to the client device 204A as per the request.
