Extract features from CAD documents Part 2: Using ezdxf

In this second part of the series of posts on extracting objects from a CAD document, I’ll go through the process of using the ezdxf package to implement the extraction strategy discussed in part one.

Extract features from CAD documents Part 1: A primer

This is the first part of a series of posts describing my experience of extracting objects from a CAD document. Motivation Recently at work a project came up that involved the optimisation of building occupancy during the refit of a 16 floor central London office block.

How to convert Jupyter notebooks to python script
