| Keywords: Identical constant-width curves side-by-side don't necessarily fit together.svg If you juxtapose two constant-width curves stroked along an identically-shaped path side-by-side they don't necessarily fit tightly together At left there's are a red curve and blue curve both made from four circle quadrants where the radius of the circle is the same as the width of the stroke If the width of the stroked line and the radius along the center of the line is 20 then the radius along the outside edge of the line is 30 radius plus half line-width and the radius along the inside edge of the line is 10 radius minus half line-width A circular arc with radius 30 cannot fit inside a circular arc with radius 10 so the two lines do not fit tightly together as seen If the two lines are moved more closely together as at right then you get areas of overlap between the two lines shown in purple and also still gaps between the two lines unless the two lines are moved so close to each other that they overlap almost everywhere Self-made SVG file created by hand in a text editor HandSVG 2013 AnonMoos SVG geometry | ||||
