# Drag away from the origin to expand the inner radius. Left-click a second time to set the inner radius and create the starting point for the outer radius.
# Drag the mouse away from the second point to expand the outer radius (or closer to contract the radius). Left-click a third time to complete the spiral.

NOTES, SPECIAL CASES OR EXCEPTIONS: Checking the '''Inner Taper''' box creates a rounded taper at the inner edge of each spiral arm by drawing an exponential curve from a user-defined edge inset point to that edge's opposite corner vertex. Checking the '''Outer Taper''' box creates a rounded taper at the outer edge of each spiral arm by drawing an exponential curve from a user-defined edge inset point to that edge's opposite corner vertex.. '''Inset Distance''' establishes an imaginary offset point positioned away from the corner vertex from the inner or outer edge. The '''Inner Radius''' setting is not available when the '''Dual Arm''' option is enabled.

DIALOG PROPERTIES
Â
'''Inner Radius''' defines the distance between the spiral's origin and the starting point of each spiral arm. '''Outer Radius''' sets the distance each spiral arm will radiate outward from the inner radius. '''Strip Width''' of the Spiral Strip can be changed by entering different values. '''Number of Turns''' defines the number of spiral revolutions of each arm '''Counter Clockwise''' (CCW) flips the clockwise drawing direction of the spiral arms.

'''Inner Taper''' creates a rounded taper at the inner edge of each spiral arm by drawing an exponential curve from a user-defined edge inset point to that edge's opposite corner vertex. '''Outer Taper''' creates a rounded taper at the outer edge of each spiral arm by drawing an exponential curve from a user-defined edge inset point to that edge's opposite corner vertex.. '''Inset Distance''' establishes an imaginary offset point positioned away from the corner vertex from the inner or outer edge. As seen below, this inset point is constrained to the sidewalls of the spiral arms. '''Point Inward''' or '''Point Outward''' renders the radial tapers (inward) towards the spiral's center or (outward) away from it.

Note that the Inner Radius setting is not available when the Dual Arm option is enabled.
Â
'''Dual Arm''' creates a second arm that mirrors the settings of the parent arm.
