Description

Conic segments are true conic sections defined by exactly three points. The first two points are the ends of the conic and the third point, the Shoulder, will lie on the interior of the conic between the first two. Alternatively, the third point can define the conic’s Tangent Intersection. Change the role of the third point using the commands in the Conic Segment Options frame, Shoulder or Tangent Intersection. In both modes the tangent lines and their intersection are displayed for reference. Additionally, the conic's ρ (rho) value can be adjusted using the provided text field.

Use the Conic Segment Options frame to change the role of the third point of a Conic segment or adjust the ρ value.
Use the Conic Segment Options frame to change the role of the third point of a Conic segment or adjust the ρ value.
