OUTLINE (OUTL) and VERTEX (VRTX)

An Outline consists of a user-defined series of connected straight lines and circular arcs (collectively known as spans). OUTL elements do not have any geometry or positional data themselves, because they are of indeterminate complexity. Geometry and positional data is provided by a list of owned Vertex (VRTX) elements. The origin of an OUTL is considered to be at the position of its first VRTX. As an alternative to straight lines and circular arcs, a smooth quadratic curve can be drawn through the vertex points of the OUTL.

(OUTL)

Setting CURFIT to CUBICFIT causes a smooth quadratic curve (which approximates a series of cubic curves) to be drawn through the vertex points of the OUTL. CURFIT DEFAULT turns off the curve-fit function.
