==============================================================================
Creates a polygon filled with a rectangular hatch of specified spacing.

        1. (POINT) first point of hatch frame and reference line
        2. (POINT) second point of hatch frame and reference line
        3. (POINT) next point of hatch frame (press <ENTER> to close frame)
        4. (NUM) hatch interval parallel to ref. line (greater than 0)
        5. (NUM) hatch interval perpendicular to ref. line
        6. (Y/N) wish to delete the hatch frame ?

Description:
This command creates a polygon as a frame for hatching and fills it with
a right angular net (hatch) of a specified spacing. The perimeter polygon may
be kept or discarded.
Create a hatch frame (polygon) by defining at least three points. Press
<ENTER> to close the polygon. Specify a hatch interval (the perpendicular
distance between the hatch lines) for the lines parallel to the reference line
and another hatch interval for the lines perpendicular to the reference line.
The area of the frame will be filled by a right angular net (hatch). The hatch
lines will be created parallel and perpendicular to the line connecting the
first two points of the frame (reference line). You are then asked whether
you wish to delete the frame or not.
