Introduction to CAD Scripting & Automation for Beginners
Interested in automating CAD tasks? Beginner's introduction to scripting: what's possible, which languages each software uses, and how to write your first script.
Who This Guide Is For
Once you're comfortable with basic CAD, scripting lets you automate repetitive tasks. This is an introduction — you don't need programming experience to understand the concepts, but you'll need some to write scripts.
Software Covered
Key Things to Consider
- Scripting = telling the CAD software what to do with text commands instead of clicking.
- Each software has its own scripting language (unfortunately, not universal).
- Start simple: record a macro of actions you repeat frequently.
- Python is the most transferable language across CAD platforms.
- Grasshopper (Rhino) is visual scripting — no code typing required.
Your Options Explained
AutoCAD (LISP)
AutoCAD uses AutoLISP — a specialized language. Good for: automating drawing tasks, batch processing files, custom commands. Start by recording Action Macros (no coding needed).
FreeCAD (Python)
FreeCAD uses Python — the most popular programming language. Great for: learning to code + learning CAD automation simultaneously. Python skills transfer to data science, web dev, etc.
Rhino (Grasshopper)
Grasshopper is VISUAL scripting (connect boxes with wires). No typing code. Great for: parametric design, generative patterns, complex geometry. Architect/designer-friendly.
Our Recommendation
Never coded before? Start with Grasshopper in Rhino (visual, immediate results) or FreeCAD Python console (transferable language). Already code? Look at your CAD tool's API documentation. Just want quick automation? Use macro recording (available in AutoCAD, SOLIDWORKS, etc.) — zero programming needed.
