  renderahouse-trees-and-plants-library.dwg / .dxf
        all 14 blocks as named block definitions (RAH-...) in one drawing

Units and scale
  Drawing units are meters, real scale (1 unit = 1 m). The files declare
  meters (INSUNITS), so AutoCAD rescales them automatically when your
  drawing's INSUNITS is set to millimeters, centimeters or feet: insert
  at scale 1. Only if your drawing is unitless, enter the scale manually
  (1000 for millimeters, 100 for centimeters, 3.2808 for feet).
  Insertion point: center of the plant in plan, ground center in elevation.

Layers
  L-PLNT-TREE  trees and palms
  L-PLNT-SHRB  shrubs and hedges
  L-PLNT-GRND  grasses and groundcover
