Curve Statement

The CURVE statement is used to establish curves that can be referred to from other statements within the scheme. The curves exist only temporarily during the execution of the input scheme and will not be stored on any data bank. Curves may be closed contours.

There are three main layouts of the CURVE statement:

• The curve is established by explicitly giving the segments which it consists of.

• The curve is established as a spline curve through a set of given points.

• The curve is established by connecting curve parts by fillet radii. The curve parts may be arbitrary contours or straight lines.
