I am about 1/2 through DanielCoffey, and for me, quite logically laid-out. A person not familiar with S3D or their photo/graphic editor might have some issues, but you do the Blender set-up very nicely. Excellent. If you made the write-up in either Libre Office or MS Office, you could save the file as a pdf for download, maybe upload it to SubSim also. PM Onkel Neal for the set-up if you do that.
