Dear @alextsui05,

First of all thank you very much for this addon, it help a lot of lifes, humans and other animals (http://ciceromoraes.com.br/doc/pt_br/Moraes/ProteseV.html).

I develop some addon that use your tool and we use it to do prosthesis and surgical planning.

Some days ago I started to rewrite OrtogOnBlender (our addon) to 2.80 and I "convert" your addon to 2.80 version.

I'm not a professional programmer, but I wold like to share the result:

I think I fixed the export error: https://gist.github.com/ahbnr/bb3f52abf0d882252b6a8e1dd88c1c07

Line

mesh = obj.to_mesh(bpy.context.depsgraph, True)

had to be replaced with

depsgraph = bpy.context.evaluated_depsgraph_get()
blender_mesh_owner = obj.evaluated_get(depsgraph)
mesh = blender_mesh_owner.to_mesh()

@cogitas3d: If the change works for you and @brothermechanic, maybe you can create a pull request with your version and this little change.

Sorry everyone for the lateness of noticing this issue. I only noticed this when I received a direct email in my inbox requesting Blender 2.8x support...

I have merged @xuser86 's PR + minor fixes and updated the version and readme. The addon has been tested and works on Blender 2.82.7, the packaged version in Ubuntu 20.04 LTS. You all may have forked the project and incorporated your own fixes at this point, but for what it's worth, the master branch of this addon is now functional on 2.8x 🙏

Also I don't know if anyone will need the old addon, but it is available on blender/2.7 branch.
