HP-GL Output
The HP-GL Output function from the
Language) format.
Control Plot
menu is used to produce pen plots in HP-GL (Hewlett-Packard Graphics
The Plotter Pen Width function is used to define the pen width for generating HP-GL output data. Structures smaller than the
plotter pen width cannot be drawn without overdraw errors. The default plotter pen width is 0.3mm. Pen width value
specifications can range from 0.01mm to 10.0mm.
The Plotter Speed function is used to control the pen plotter speed, i.e., the speed at which the pen can be moved by the HPGL plotter. The system accepts either S input for maximum speed or non-negative integer plotter speed values in cm/s
units. The default plotter speed corresponds with S (maximum speed). The maximum speed value specification is 99cm/s.
The HP-GL coordinates are written in plotter units where 40.2 plotter units are 1 millimeter. Some HP-GL "compatible"
plotters are based on 40 plotter units per millimeter. The Plot Scale function can be used to specify a scale factor for producing
true to scale output with non-default plotter units. The default plot scale value is 1.0 for true to scale output. Plot scale
specifications can range from 0.1 to 100.0.
The Fill Mode HP-GL function provides the options Fill Mode Off and Fill Mode On . Fill Mode Off causes the system to refrain from
filling the plot structures, i.e., only outlines are drawn for filled areas. Switching off the fill mode is most useful for fast control
plots. Fill Mode On is used to select the default fill mode.
The HP-GL Output function is used to produce HP-GL pen plots. The user is prompted for the plot layer and the pen number
(1..99), and for the name of the output file (if no default output device was specified with Plot Device ). Note the Multiple Layers
option provided with the layer selection menu of the HP-GL Output function. This option can be used for writing the plot data
of multiple selectable layers to a single output file. With the Multiple Layers option a popup menu is provided for selecting
and/or deselecting the plot data output layers using the right mouse button. Layer selections with the left mouse button also
allow for layer-specific pen number selections (on default pen 1 is used for each layer). The Col. button is used to select all
currently visible layers for output, with the pen numbers automatically set to modulo eight of the corresponding layer colors.
Use the following commands to set the plotter pen width to 0.2mm, set the plotter speed to 10cm/s, switch off the fill mode
and plot the documentary layer Insertion Plan - Side 2 of the currently loaded layout to an HP-GL plot file named
demo_bs2.plt using pen number 1:

After successfully generating the HP-GL plot file, the CAM Processor issues a HP-GL plot done (<n> errors)!
message where <n> is the number of overdraw errors. Overdraw errors are highlighted on the layout.
A PG HPGL command is added to the end of HPGL output files to force a page eject and to prevent from subsequent plots
being plotted onto the same sheet. The Multiple Layers option must be used for plotting multiple layers onto the same sheet.
