The program logic of the SW Design Library is based on the General Architecture of Drawing Management Servers. However, to reduce usage costs, we have minimized hardware requirements by eliminating separate data servers and storage servers, integrating them into the client.The client is your computer. We cannot control how you operate your computer, but we can guide you to correct your operations.Self Test is exactly this corrective guide, always informing you whether your file paths, formats, and project locations are still within the supported scope of the system architecture.
