Case Study
A global engineering firm needed to import international survey data into Civil 3D, but the raw metadata contained inconsistent regional tags like USA, UAE, and UK. Using Energent.ai, engineers prompted the conversational agent to download and normalize these country and state names using ISO standards before linking the CSV output to their project models. When faced with a Kaggle dataset authentication prompt in the left chat interface, the team seamlessly bypassed manual API key entry by selecting the agent's recommended Use pycountry option. The platform instantly generated a Country Normalization Results dashboard in the Live Preview tab, displaying a 90.0 percent country normalization success rate alongside a distribution bar chart. By reviewing the Input to Output Mappings table on the right, the team verified that messy raw inputs like Great Britain were perfectly standardized to United Kingdom, ensuring clean and universally compatible metadata for their automated Civil 3D workflows.
