The invention relates to a mold pattern copying system and method.

Manufacturing is the basis for the survival and development of human society. With the rapid development of automobiles and light industry, the design and manufacture of molds has gradually attracted widespread attention and has formed a basic industry of the national economy.

In the mold design, since the main structure, partial structure, component structure and standard holes of the mold are realized in a layered manner, this results in a layer having about 60% of the same pattern as the other layer and the same position of the figure. Case. Therefore, it is often necessary to copy all or part of a layer to another layer during mold design.

There are a lot of problems when copying a graphic on one layer to another layer. For example, first, the original position information of the graphic is lost, and the position of the graphic cannot be found on the new layer. Second, the graphic to be copied may be Including attribute primitives, attributes of attribute elements are often discarded during the copy process, and attributes need to be added manually for each element with attributes. Third, for parts or holes, it cannot be copied during the copy process. The associated part or hole is copied together. This is a waste of time, design efficiency is greatly reduced, and it is easy to make mistakes.

In view of the above, it is necessary to provide a mold pattern copying system and method that can quickly and easily copy mold patterns from one layer to another.

A mold pattern copying system, the system comprising a host and a database, the data stock storing a mold graphic and a position of the mold graphic at a layer to which the template belongs, the host comprising: a selection module for selecting from a source layer a graphic to be copied, and a selection target layer; an acquisition module for obtaining a position of the graphic to be copied from the database at the source layer; and an extraction module for extracting each primitive in the graphic to be copied, And classifying the primitives as non-attribute primitives and attributed primitives; and copying modules for directly copying non-attribute primitives to the destination layer; the copying module is further configured to store attribute primitives Attribute, and copy the attribute element to the destination layer; the mobile module is used to move all the elements in the destination layer to the corresponding position of the layer according to the position of the graphic to be copied at the source layer; The attribute stored above is given to the attribute element.

A mold pattern copying method, the method comprising the steps of: (a) selecting a graphic to be copied from a source layer; (b) selecting a destination layer; (c) obtaining a position of the graphic to be copied at a source layer; (d) extracting Each primitive in the graphic to be copied, and classifying the primitive into a non-attribute primitive and an attributed primitive; (e) directly copying the non-attribute primitive to the destination layer; (f) storing the attribute The attribute of the primitive, and copy the attribute primitive to the destination layer; (g) move all the primitives to the corresponding position of the layer in the destination layer according to the position of the image to be copied at the source layer; (h) Stored attributes are assigned attribute primitives.

Referring to Figure 1, there is shown a hardware architecture diagram of a preferred embodiment of the mold pattern replication system of the present invention. The hardware architecture of the system mainly includes: an input device (including a keyboard 12 and a mouse 14), a display 16, a host 10, and a database 18.

The display 16 is used to provide a graphical user interface (GUI).

The host 10 can be an IBM-based computer (IBM Personal Computer, IBM PC), an Apple Mac PC, a personal computer, a web server, or any other suitable computer.

The database 18 is responsible for storing the mold pattern, the position of the mold pattern at the layer to which it belongs, and the individual elements that make up the mold pattern. The database 18 also stores attributes of individual primitives in the mold graphic, including attributes, processing methods, associated primitives, and precision.

Referring to FIG. 2, it is a functional module diagram of the host in FIG. The module referred to in the present invention is a computer program segment for performing a specific function, and is more suitable for describing the execution process of the software in the computer than the program. Therefore, the description of the software in the present invention is described by a module.

The host 10 includes a selection module 301, an acquisition module 302, an extraction module 303, a replication module 304, a mobile module 305, and an association module 306.

The selection module 301 is configured to select a graphic to be copied from a certain layer (ie, a source layer), and may select all the graphics of the layer, or select a partial graphic of the layer.

The selection module 301 is further configured to select a destination layer, where the destination layer refers to a layer to which the selected graphic is to be copied. Specifically, the selection module 301 selects the destination layer and determines whether the selected destination layer is suitable: first determining whether the destination layer exists, and if the destination layer does not exist, reselecting; and then determining whether the destination layer is locked, If the destination layer is locked, the destination layer is unlocked.

The obtaining module 302 is configured to obtain, from the database 18, the location of the graphic to be copied at the source layer.

The extraction module 303 is configured to extract each primitive in the graphic to be copied and classify the primitive. Specifically, the extraction module 303 splits the graphic to be copied into a single primitive, and then acquires the attribute of the primitive from the database 18. If the acquired attribute of the primitive is empty, the image is extracted. The element is classified as a non-attribute element. If the attribute of the obtained element is not empty, the element is classified as having an attribute element.

The copy module 304 is configured to directly copy the attributeless primitives to the destination layer.

The copy module 304 is further configured to copy the attributed element to the destination layer. Specifically, first, the copy module 304 determines, according to the attribute of the primitive acquired from the database 18, whether the attributed element has a primitive associated with the attribute element: if the attributed element has no The associated primitive stores the attribute of the attributed primitive; if the attributed element has a primitive associated with the attribute, the attribute of the element associated with the attributed element is obtained, and Stores the attributes of the attributed entity and the attributes of the associated element. Then, the copy module 304 copies the attributed primitive to the destination layer.

The moving module 305 is configured to move all the primitives (including the attributeless primitives and the attributed primitives) to the corresponding positions of the destination layer according to the position of the graphic to be copied at the source layer, that is, at the destination layer. Move all of the above elements to the same coordinates as the source layer.

The association module 306 is configured to respectively assign the attributes stored by the replication module 304 to the attribute primitives and the primitives associated with the attribute primitives, and associate the associated primitives with the associated attributes. The primitive performs the associated operation.

Referring to Figure 3, there is shown a flow chart of a preferred embodiment of the mold pattern copying method of the present invention.

In step S401, the selection module 301 selects a graphic to be copied from a certain layer (ie, a source layer), and may select all the graphics of the layer, or select a partial graphic of the layer.

In step S402, the selection module 301 selects a destination layer, and the destination layer refers to a layer to which the selected graphic is to be copied. Specifically, the selection module 301 selects the destination layer and determines whether the selected destination layer is suitable: first determining whether the destination layer exists, and if the destination layer does not exist, reselecting; and then determining whether the destination layer is locked, If the destination layer is locked, the destination layer is unlocked.

In step S403, the obtaining module 302 acquires, from the database 18, the position of the graphic to be copied in the source layer.

Step S404, the extraction module 303 extracts each primitive in the graphic to be copied and classifies the primitive. Specifically, the extraction module 303 splits the graphic to be copied into a single primitive, and then acquires the attribute of the primitive from the database 18. If the acquired attribute of the primitive is empty, the image is extracted. The element is classified as a non-attribute element. If the attribute of the obtained element is not empty, the element is classified as having an attribute element.

In step S405, the copy module 304 directly copies the attributeless primitives to the destination layer.

In step S406, the copy module 304 copies the attributed element to the destination layer. Specifically, first, the copy module 304 determines, according to the attribute of the primitive acquired from the database 18, whether the attributed element has a primitive associated with the attribute element: if the attributed element has no The associated primitive stores the attribute of the attributed primitive; if the attributed element has a primitive associated with the attribute, the attribute of the element associated with the attributed element is obtained, and Stores the attributes of the attributed entity and the attributes of the associated element. Then, the copy module 304 copies the attributed primitive to the destination layer.

Step S407, the mobile module 305 moves all the primitives (including the attributeless primitives and the attributed primitives) to the same position of the destination layer according to the position of the graphic to be copied at the source layer, that is, the target layer will be All of the above primitives move to the same coordinates as their source layer.

Step S408, the association module 306 assigns the attributes stored in step S406 to the attribute primitives and the primitives associated with the attribute primitives, and performs the associated primitives and associated attribute primitives associated with the attribute primitives. Associated operations.
