I am creating an equipment front panel from milled/engraved aluminum ([login to view URL]). I will be creating a simple diagram as part of the panel, and need three icons for that diagram. The panel creation software accepts HPGL vector files. The engraving is lines in a single colour, and will be approximately 1" square. The engraving tool is either 0.2mm or 0.4mm in diameter.
"A HPGL engraving is based on a two-dimensional vector graphic, which consists of lines with a custom contour described in HPGL format."
I need thee icons created, in HPGL format, in a simple fashion for engraving as above. Examples of the three icons are attached. The final result does not have to match these exactly. The three icons should have the same general look and feel.
