hi michael

this is looking great! As i have mentioned before I am a technical illustrator so its important for me to be able to work with vector versions of the 3D assets. This is a big step forward, you're not far off the $10,000 application we use! One comment I would like to add which would make working with this output far easier. Is it possible to have two different line thicknesses depending on what kind of edge it is? As you can see from my attachment I have thick and thinned your pdf, it gives it a more 3D look and feel and is a standard in tech documentation. It would be good if the lines could be differentiated like my pdf, it doesn't matter how thick as this is easily changeable document wide in illustrator.

I'm not sure if all the hidden lines are the thin lines though, but even on the expensive software you have to decide wether to keep or delete certain thin lines. Some lines like around the ankle joints are not edges but we keep them to help the viewer visualise the form. An analogy we use id if an insect walked over the model/lines and then disappeared from view then it would be a thick line . .

As i said before this is a huge leap in my line of work, well done!
