I am a Landscape Architect and am beginning to work in 3d. I want to be able to create designs in 2d and 3d simultaneously. Can I create a 3d plant from a 2d plant symbol? The 3d plant library provided has only six 3d plant symbols. Is there a larger library available?

When using the property line tool and trying to draw a curve, the curve is swung the opposite way of the way it is supposed to be. I am taking information off of a plat of survey and the only information given is the arc distance, the chord length, and the bearing. I also interpolated the radius off of the plat. Is there some sort of trick to doing this?
