VARKON Version 1.15 1997-10-16
Description
Creates a circular arc with specified origin, radius, start and end
angle. Angles are measured relative to the X-axis of the active coordinate
system and the arc turns from the start angle to the end angle in counter
clockwise direction. The sense of direction for an arc is from the start
angle towards the end angle. The parametrisation of an arc is relative
to angle (arclength) with t=0 for the start angle and t=1 for the end angle.
The resulting 3D arc is always placed in the XY-plane of the active coordinate
system. If the origin is not in this plane (origin.z <> 0 ) it will
automatically be projected to Z=0 before the arc is created.
Available in
3D.

Comments
The radius of an arc must always be greater than zero.
Angles may be specified in the range of -360 to +360 degrees. The start
angle must be smaller than the end angle.
The Z-component of the specified origin is currently not used. The arc
is always placed in the XY-plane (Z=0) of the active coordinate system.
This however may change in a future version of VARKON so it is recommended
to always set the Z-component explicitly to zero.
