## Overview

SolidDNA is a C# framework that wraps the SOLIDWORKS API and provides add-in integration plus higher-level APIs for working with the application and its models. A user can start from a SOLIDWORKS add-in or the standalone template, connect through the integration layer, and use framework wrappers to interact with SOLIDWORKS; command UI and localization are additional capabilities. The excerpts show integration and command-manager relationships, but most model-domain implementations were not sampled, so their internal call paths are not inferred.
