converts one or more Materials and Geometry Format (MGF)
files to a 2-D orthographic projection along the selected axis in the
All geometry is clipped to the specified bounding box, and the
resulting orientation is as follows:
x Y-axis right, Z-axis up
y Z-axis right, X-axis up
z X-axis right, Y-axis up
If multiple input files are given, the first file prints in black,
the second prints in red, the third in green and the fourth in blue.
If more than four input files are given, they cycle through the
colors again in three other line types: dashed, dotted and
option may be used to randomly throw out line segments that are
shorter than the given
(given as a fraction of the plot width).
Segments are included with a
probability equal to the square of the line length over the square
of the threshold.
This can greatly reduce the number of lines in the drawing (and
therefore improve the drawing speed) with only a modest loss in
A typical value for this parameter is 0.005.
All MGF material information is ignored on the input.
