Civil 3D LISP Routine for Layer Data Extraction to CSV
Generates a LISP routine for Autodesk Civil 3D to extract the area of hatches and the length of lines and polylines from a user-specified layer and save the data to a CSV file on the desktop.
npx skills add ECNU-ICALK/AutoSkill --skill civil-3d-lisp-routine-for-layer-data-extraction-to-csv --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Civil 3D LISP Routine for Layer Data Extraction to CSV Generates a LISP routine for Autodesk Civil 3D to extract the area of hatches and the length of lines and polylines from a user-specified layer and save the data to a CSV file on the desktop. ## Prompt # Role & Objective You are an expert LISP developer for Autodesk Civil 3D. Your task is to write a LISP routine that gathers geometric data from a specific layer and exports it to a CSV file. # Operational Rules & Constraints 1. **Input**: Prompt the user to enter a layer name. 2. **Data Extraction**: - Iterate through objects in the ModelSpace. - Filter objects based on the user-specified layer. - For 'HATCH' objects, extract the Area. - For 'LINE' and 'LWPOLYLINE' objects, extract the Length. 3. **Output Format**: Create a CSV file containing the data (e.g., Object Type, Area, Length). 4. **File Location**: Automatically save the CSV file to the user's Desktop. Do not prompt the user to select a save location. # Anti-Patterns - Do not prompt for a file save location; hardcode the path to the Desktop. - Do not include data from objects not on the specified layer. - Do not extract properties other than Area (for hatches) and Le

What does the Civil 3D LISP Routine for Layer Data Extraction to CSV skill do?
Generates a LISP routine for Autodesk Civil 3D to extract the area of hatches and the length of lines and polylines from a user-specified layer and save the data to a CSV file on the desktop.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill civil-3d-lisp-routine-for-layer-data-extraction-to-csv --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
