Problems solved by technology

In this way, CAD data for "cut-away three-dimensional model" is created by the hands of a CAD operator with expertise. Even if the internal structure can be observed, in this "cut-away three-dimensional model", there are still cases where buildings or civil engineering cannot be observed. Difficulties in the structure and appearance of the "whole" work object

Embodiment approach 1

[0082] figure 1 It is a block diagram showing the outline of the CAD data processing apparatus according to Embodiment 1 of the present invention. As shown in the figure, the CAD data processing apparatus 100 includes a control unit (CPU) 110, an input unit 120, an output unit 130, a communication unit 140, a storage unit 150, and a display unit 160. The storage unit 150 stores a gap width GAP suitable for dividing the target object by the target three-dimensional printer in advance. The control unit 110 has an acquisition unit 111, an input receiving unit 112, a processing unit 113, and a three-dimensional output control unit 114. The acquisition unit 111 acquires three-dimensional CAD data of the three-dimensional object. The three-dimensional CAD data is generated by the CAD system CD1, received by the communication unit 140 via the network NET, and finally delivered to the acquisition unit 111. The acquired three-dimensional CAD data is modeled as a three-dimensional mode...

Embodiment approach 2

[0094] Picture 9 It is a block diagram showing the outline of a CAD data processing apparatus according to Embodiment 2 of the present invention. As shown in the figure, the CAD data processing apparatus 200 has a control unit (CPU) 210, an input unit 220, an output unit 230, a communication unit 240, a storage unit 250, and a display unit 260. The storage unit 250 stores the gap width GAP suitable for dividing the target object by the target 3D printer in advance. It is the same as in the first embodiment, but in the second embodiment, it also stores the surface that should be attached to the side of the three-dimensional object in contact with the divided area. The pattern data PD. The pattern data PD is composed of one or more patterns selected from the group consisting of colors, patterns, characters, signs, marks, graphics, reinforcement drawings, structural cross-sectional views, maps, design drawings, wiring diagrams, and three-dimensional shapes. constitute. The cont...

Embodiment approach 3

[0106] Figure 14 It shows the outline of the CAD data processing apparatus of Embodiment 3 of this invention. As shown in the figure, the CAD data processing device 300 has a control unit (CPU) 310, an input unit 320, an output unit 330, a communication unit 340, a storage unit 350, and a display unit 360. The storage unit 350 stores the gap width GAP suitable for dividing the target object by the target 3D printer in advance, and the pattern data PD that should be pasted on the surface of the three-dimensional object that is in contact with the divided area, as in the second embodiment, but In the third embodiment, the shape data FD indicating the shapes that should be provided on the surfaces of the two or more divided (cut) objects that are in contact with the divided regions of the three-dimensional object are stored. The shapes that fit into each other are, for example, a concave portion / hole portion on one side, and a convex portion / protrusion portion that can be accommo...

Abstract

Provided are a CAD data processing device and a CAD data processing method suitable for producing a solid product by a three-dimensional printer. The CAD data processing device (100) comprises a control unit (110), an input unit (120), an output unit (130), a communication unit (140), a storage unit (150), and a display unit (160). The control unit (110) comprises an acquisition unit (111), an input reception unit (112), a processing unit (113), and a three-dimensional output control unit (114). The acquisition unit (111) acquires three-dimensional CAD data of a solid product, the input reception unit (112) receives an input operation designating at least one of division instruction surfaces which divide the solid product, and the processing unit (113) processes the three-dimensional CAD data so that the solid product is divided (cut) by the division instruction surface and a division area defined by a gap width.

Description

Technical field [0001] The invention relates to a CAD data processing device and a CAD data processing method, in particular to a CAD data processing device and a CAD data processing method for processing three-dimensional CAD data. Background technique [0002] At present, in product development, several experimental products are produced in the design or development stage to evaluate appearance and performance. The most primitive experimental models include clay models made of clay or wooden models made by scraping wood (wood). However, this type of model production consumes labor, time, and money, and has poor reproducibility, and there is a problem that it is excessively dependent on the skills of model production professionals. In place of this existing experimental model making technology, at the current stage of computer technology development, the "rapid prototyping" technology of generating developed products through three-dimensional CAD has been developed and used the...
