I do three dimensional design and builds of projects in my head. hardly ever need drawings or plans. I visualise the project, rotate and design, then test mechanically. Quite complex systems, EQM mounts, scopes, optical systems, obs boats, cars etc Then I attempt to find the parts I need to make them, my garage has a lot of 'junk'.
Find it hard to understand why people cannot 'see' my concept when I can get it down to very specific dimensions, materials, functionality etc.
Weird eh ?
And yes, I can 'play' music in my head, not compose but 'listen' to favourites artists, songs etc, even 'video' for some.
