Restrictions
When exporting Arbortext IsoDraw files, every effort is made to depict as many attributes as possible in HPGL format. However, it is not possible to describe all elements and attributes in HPGL.
Fonts
All text elements are saved in the HPGL standard font.
Masked Elements
The element used as a mask and all masked elements are grouped together, but remain visible.
Fills
Fills cannot be depicted in HPGL format.
