The Bowness of a Circular Arc

To create a circular arc in a shapesheet’s Geometry section, requires the specification of where the arc ends and a cell called “A” that holds the measurement of how much the arc differs from a straight line between the end points of the arc. The deflection indicates how much the arc bows. It is possible to fragment a circular shape to get an idea of a value of “A”, but it is a value not a formula. So what is a formula to describe the content of the “A” cell? To determine a formula, you need to revisit your grade … Continue reading The Bowness of a Circular Arc
