add_the_tube_extensions_to_the_drawing: Add any tube extensions to the frame drawing
In ghuiber/bicycle: Design a bicycle frame

Description Usage Arguments Details Value See Also

If this is a welded frame, you can set the difference between the top of the head tube and the point where the top tube joins the head tube (measured center-to-center). You can also set the difference between the top of the seat tube and the center of the point where the top tube meets the seat tube. Both of these differences are "tube extensions" that, if set, can be drawn.

add_the_tube_extensions_to_the_drawing(
  x,
  df,
  wheel_diameter = 622,
  c = I("black"),
  alpha_factor = 1
)

`x`	An existing ggplot object. At a minimum, it's a scatter plot of the rear dropout center. But it can be a bicycle frame of a previous design already drawn, onto which you can now overlay a new design using the dims in `df` for easy comparison.
`df`	A frame design tibble, such as the minimal one drawn by `wrap_frame_dims()` or the one augmented by `find_ht_extension_and_add_true_fork()`.
`wheel_diameter`	Wheel diameter in millimeters; 622 is the bead seat diameter of a 700c wheel. To see the effect of the tire width, add 2 x tire width in millimeters – i.e. specify `wheel_diameter = 622 + 2 * 32` for a 32 mm tire.
`c`	The color of the line segments.
`alpha_factor`	The transparency of the line segments, `alpha`.

A complete df tibble as drawn by wrap_frame_dims() is necessary. If it contains no tube extensions, the x ggplot object will be returned unchanged.

A ggplot object.
