HPGL files are generally used for driving plotters. A reference or starting point therefore needs to be defined for the plotter when exporting. This starting point is the bottom left corner of the drawing.

Enter the required dimensions measured from the edge of the sheet. Remember that not every plotter is able to plot right up to the edge of the sheet.

When exporting a file, all elements are generally arranged in the way they appear in an Arbortext IsoDraw drawing, i.e. elements located at the rear of the illustration are drawn first. If the HPGL file is then employed on a plotter that uses pens, the pen will have to be changed for virtually every element since the line thicknesses of the elements change frequently.

In order to avoid this, check the relevant box. All elements or element parts requiring pen 1 are then plotted first, followed by all elements requiring pen 2, etc.
