It has been designed to work with the grid snap turned on and the grid size set to 9 (the default). This minimum resolution (9 pixels) corresponds to 0.05 inches when printed at 40% scale (using Page Layout). Printing at 80% will produce 2:1 scale output. Each pad in this palette is an eps image. An accompanying diagram, "PCBLayoutPadSizes", gives the dimensions of each item in this palette. \
Points have been added on top of each image, and the point and image then grouped together. Make sure you draw lines to the point, and not the image itself, since lines drawn to eps images "begin" at the edge of the bounding box (possibly leaving a gap between the line and the pad). After all lines to the pads have been drawn, send them to the back (Command-B) so they are not visible in the "hole" in the centre of the pad. After all connections have been made, the fastest way to get rid of an unused point is to draw a line from the point to the image underneath it.\
Warning: The accuracy of the NeXT laser printer may be inadequate for large layouts.
