Hey @thehomme ,
Your absolutely right, this ISN’T a course about mesh modelling.
It is however, a course covering the fundamentals of mesh modeling.
All our fundamentals courses cover the ‘basics’ of the tools and where to find them, for the associated topic, eg. Mesh Modeling, Animation, etc., etc..
These fundamentals are designed for beginners to Blender.
You use terms such as Radial Symmetry and Deformers, these are not Blender terms. It maybe advisable to forget, or put aside, what you know from other software to learn Blender efficiently.
Omar has suggested 2 courses better suited to learn modeling in Blender, I hope you find them more suited to your needs.
