I've been looking around for a reliable way to get object & vehicle diagrams into blender, so I found this extraordinary file called the DXF format which for a long time, has allowed me to export diagrams with a reliable degree of accuracy until it recently broke.
I knew that there were .dxf exporters for Inkscape, so I looked around for the most modern & up to date exporter, to try to get the best results, and I found a few, but they seem to require something called "lxml" to be downloaded from http://cheeseshop.python.org/pypi/lxml/
The message came was the following:
While I could find the lxml, I couldn't find out how to actually install the package.The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension.Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml
No module named lxml
