Objective: To learn how to categorize components in your library by functionality.
Difficulty: Easy.
In this article:
Easily find and filter through your component library by attributing components with categories. Grouping similar components together will cut back on wasted time spent searching for parts, thus helping you and your team work faster and more efficiently.
Introduction
Each component must be assigned a category. There are five major category groups, each with its own list of categories.
Each category is associated with a specific prefix value for generating the corresponding Customer Part Number (CPN).
To help engineering teams get up and running quicker with Duro, a default out-of-the-box list of categories and a CPN format widely accepted in the industry by any supplier or contract manufacturer is provided. For custom category and CPN format schemes, please contact help@durolabs.co for more information.
