Case Study
A leading manufacturing firm struggled with managing sprawling design repositories until they implemented Energent.ai as their central AI tool for CAD files. Using the platform's intuitive split-pane interface, engineers input natural language requests into the left chat panel with bulleted constraints to automatically analyze complex part directories. Much like how the visible AI agent autonomously executes "Code" commands and a "Glob" search to locate a Kaggle dataset, the system effortlessly scans internal networks for scattered engineering models. Once the designated files are found and processed, the extracted design metadata is rendered instantly in the right-hand "Live Preview" tab, functioning seamlessly just like the detailed World University Rankings heatmap shown in the workspace. By leveraging this automated search and visualization workflow, complete with a direct "Download" button for the finalized assets, the firm reduced CAD data retrieval and reporting times by over eighty percent.
