It's not a bug it's a feature! Examine your lines with a magnifier. You'll find that whereas an arc (or a circle) is drawn with a pen that remains radially oriented (so you get a flat end on the end of an arc), a line is drawn with a "square" pen. The ends of a line segment (especially if it is a thick line) look like: ___ / | / / / / Thus diagonal lines are about 1.4 times as thick as horizontal or vertical ones. Presumably this is to allow lines to meet at neat right-angle corners, which is not what you want. You could try a custom line thickness of .707 for diagonal lines. See if you can find something that lets you define the SHAPE of your line-drawing pen. The only problem with this is that you'll end up with round ends on your lines. You could of course paint the lines with a round brush-tool, but it's not quite the same. --------- Tom Evans tom@wcc.oz.au | Webster Computer Corp P/L | "The concept of my 1270 Ferntree Gully Rd | existence is an Scoresby VIC 3179 | approximation" Australia | 61-3-764-1100 FAX ...764-1179 | D.
