# Left-click to establish the location of the fractal tree. A default horizontal fractal tree appears in the project workspace.
# The fractal dialog opens up on the lower right corner of the screen. You have two options: fractal tree with linear or cylindrical branches. You can also set the number of fractal levels.
# Make sure to click the <b>OK </b> button of the dialog to complete the fractal construction.
NOTES, SPECIAL CASES OR EXCEPTIONS: The parameter '''Gen. Factor''' determines how many new next-level branches are generated at the end of each branch. '''Separation Angle''' sets the angle between each pair of branches at each node. The '''Prune Factor''' determines what percentage of branches are removed randomly at each node. With a default zero prune factor, all the branches are kept. The parameter '''Thickness''' represents the diameter of the main branch in the case of a cylinder key object. The parameter '''Thickness Factor''' determines the tapering of each cylindrical branch from its start point to the end point. A zero thickness factor means no branch tapering.
