**NAME**

THREED - 3-d line drawing package.

**SYNOPSIS**

CURVE3 - Draws the projection of a curve defined by a sequence of points in 3-space. FENCE3 - Draws the projection of a curve, just as CURVE3 does, but with a "fence" of straight line segments that are parallel to one of the three axes and that extend to a specified plane perpendicular to that axis. FRST3 - Specifies the first in a sequence of points connected by straight-line segments, the projections of which are to be drawn. (FRST3 is called for the first point in the sequence and VECT3 is called for the rest.) LINE3 - Draws the projection of a straight-line segment. PERIM3 - Draws the projection of a rectangular perimeter in a plane parallel to one of the three coordinate planes, with inward-pointing tick marks at specified intervals. POINT3 - Draws the projection of a point. PWRZT - Draws the projection of character strings that are positioned in a plane parallel to one of the three coordinate planes. SET3 - Defines the transformation from three dimensions to two dimensions. TICK43 - Gives user control of tick mark length in PERIM3. VECT3 - Defines the second and all subsequent points in a sequence of points connected by straight-line segments, the projections of which are to be drawn. (FRST3 is called for the first point in the sequence and VECT3 is called for the rest.)
