REGULAR POLYGON (FILL AREA SET)

PXPOLY

CALL SEQUENCE

CALL PXPOLY (X, Y, RADIUS, NSIDES)

INPUT PARAMETERS

REAL X

X coordinate of the center in MC

REAL Y

Y coordinate of the center in MC

REAL RADIUS

Radius of the polygon in MC

INTEGER NSIDES

Number of sides

EFFECT

A Fill Area Set element is created by computing the vertices of a regular polygon with the specified center, radius, and number of sides. For example, if the number of sides is 5, the polygon is a regular pentagon. The fill area set has a single boundary. All Z values are equal to zero.

Depending on the edit mode, the fill area set is inserted into the open structure after the current element or replaces the current element. The newly inserted element becomes the current element.

Minimum number of sides is 3.

This function is equivalent to computing the points and using them in a call to the Fill Area Set function (routine PFAS).

ERRORS

5

Ignoring function, function requires either state STNOP or state STOP.
