I'm looking for suggested layouts that I can modify on screen, then
view in 3D.

Hi,
You'll find that most folks on here aren't that keen on existing software -
too clunky, and constricting. There are so many factors to take into account
in terms of climate, soil type, aspect, altitude, shadows from buildings,
before you begin to consider the individual plants, their age, growth rates
etc. We need better computing brains to build better programmes.
