My dear friend Gaelle asked me to add the fascias to the model and I just started last week.
The result can be seen on the latest version which is downloadable on the 'Home' page of this website.
Within the TA2, more than 110 structures contain the word 'fascia' (and I did not count the 'fascilculus','fasciculi' and the other 'fascicle'-ish names).
Several visual options can be used to get a beautiful render (as the 'Wireframe' modifier or the wireframe display option in the object properties panel).
For the moment I chose a semi-transparent material, in order to be able to see which muscle are contained within each particular compartment.
Useful trick: To select a structure that is hidden behind or contained inside another, you can 'Alt-Left Mouse Button' (Alt+LMB) on it, and it will open a panel with all the structures placed behind the mouse cursor; then simply choose the one you need.
You can then reach its collections with the RMB (Right Mouse Button) shortcut imported with the 'Anatomy-shortcuts.py' contained in the zipped file.
