Title:
METHOD EMPLOYING ASSEMBLY CONSTRAINTS AND COLLISION DETECTION TO AUTOMATICALLY GENERATE HIERARCHICAL EXPLODED VIEW
Document Type and Number:
WIPO Patent Application WO/2020/147483
Kind Code:
A1
Abstract:
Disclosed is a method employing assembly constraints and collision detection to automatically generate a hierarchical exploded view. To reduce the number of attempted explosion operations and improve explosion efficiency, explosion sequencing and layering of parts are determined according to a design result of a three-dimensional assembly process, and grouping of parts to be exploded in each layer is determined according to identical or similar parts and disassembly directions. For each layer of parts, a viable explosion direction is determined according to an assembly constraint and collision detection, an explosion sequence and an explosion direction are determined for the layers of parts, and hierarchical explosion is performed in accordance with a specific distance. After an exploded view containing all parts is completed, balloons and a part list of the parts are generated. The present invention achieves a simple and convenient design, performs layering with respect to an explosion sequence of parts in advance and grouping of parts to be exploded in each layer, and determines an explosion direction to be attempted by means of an assembly constraint, thereby effectively reducing the number of attempted explosion operations, further improving explosion efficiency and an explosion effect, and meeting demands for exploded views during a product operation and maintenance stage for purposes such as product use and training manuals.
