Thank you Alexander. I know of this seminal work but have yet purchase it. Should have years ago, ALAS!
Believe it or not I still hand draw although if time and money allowed I would invest in Vectorworks. I work on a Mac and hesitate to introduce any Windows software. Also, I would love tutorials on the program but living on Cape Cod has a few drawbacks; i.e. very limited resources. I would need to commute to Boston and I am way over doing that anymore. If there was someone near the South Shore, south of Boston, I would be able to do that for private lessons.
