AI + Python for AutoCAD Civil 3D
Start with a focused 6-hour Python Foundations in PyCharm, then automate Civil 3D using pywin32/COM and ezdxf, with ChatGPT as your coding partner. Build QC reports, batch plotting, COGO-like points from CSV, station–offset tables, and quick cut/fill estimates.
Duration: ~18–20 hours
Teaching Methodology: Hands-on, project-based
Course Schedule: Schedule
Fees $1200
Course Mode: Blended — Face-to-face or online via Zoom
OVERVIEW
This course turns Civil 3D users into automation pros. After a practical Python introduction, you will control Civil 3D via COM and DXF pipelines, with ChatGPT helping you draft, refactor, and test your scripts.
AUDIENCE
Civil engineers, surveyors, CAD/BIM technicians, and infrastructure design teams.
PREREQUISITES
Completion of Civil 3D Essentials. No prior coding required. Python 1 is helpful but not mandatory.
CERTIFICATION
ETC is an Autodesk Authorized Training Center. International certificates from Autodesk are issued upon completion.
Frequently Asked Questions
Do I need Python experience?
No. We begin with a 6-hour Python Foundations module using PyCharm.
Can I automate my existing drawings?
Yes. You’ll build batch plotting, QC reports, station–offset tables, and more—targeting your own DWGs/DXFs.
