In order to efficiently retrieve standard parts from a large library, it's essential to organize them using a clear hierarchical structure. The standard parts are grouped into two levels: the top level categorizes them based on international standards such as ANSI Inch, ANSI Metric, DIN, CB, ISO, JIS, and others. Below this, the second level organizes the parts according to their functions—for instance, under ANSI Metric, you'll find categories like bolts and screws, nuts, pins, springs, washers, and more. This structured approach makes it much easier to search for and reuse standard components quickly.
Reusing standard parts goes beyond just using geometric models—it involves a wealth of additional information. First, there is the geometric data that defines the part, including its features and associated parameters. When reusing these parts, the process often involves driving dimensions to fit specific design needs. Feature-based parametric modeling in 3D CAD systems allows for accurate representation and customization of standard parts.
Second, assembly information plays a key role. This includes the geometric constraints between parts and the assembly, which are crucial for maintaining proper relationships during the design process. It also involves assembly features like axes, points, or other reference elements that help define how parts interact with each other.
Third, there's a range of related data connected to each standard part, such as links to schematic diagrams, dominant parameters, hole geometry, hole parameters, expressions, and assembly features. All these associations are stored in an XML file, making it easy to manage and access the necessary information. When a designer uses a standard part during the design process, the template is called and customized into a specific instance—this is known as instantiation. This method ensures consistency, reduces redundancy, and speeds up the overall design workflow.
