-When (e.g.) routing 5mm power traces on a small grid, it's not always easy to hit the
-point where the trace ended (which is the center of the semicircle at the end of the
-line) to start the next line. If you have selected the line tool, finding the end of
-the line can become guesswork as the cursor doesn't change shape like it does with the
-select tool.
-I want my traces to consist of lines and arcs that are perfectly connected and I want
-to work as fast as possible.
-
-Attached is a small patch that
-
- - makes it possible to deactivate snapping to "some sensible point along a line".
- (that's what a comment in the code says). This snapping algorithm gets in the way
- sometimes so you have to slowly go over a line to find out where it really ends,
- bouncing back and forth between the points of the small grid, the end of the line
- and these "sensible points", which is wasting time. The command is
- "Display(ToggleSnapOffGridLine)". It is still activated by default to avoid
- violating POLA.
-
- - more importantly, introduces a new command called "Display(ToggleHighlightOnPoint)"
- that highlights all lines and arcs which have (end)points exactly on the position
- where the cross hair is currently snapped to. It therefore helps finding the end
- points of lines and arcs, but sometimes also shows redundant traces, traces that
- aren't perfectly connected to each other, traces that don't end directly on the
- center of a via but should, etc. It works with thin draw too and I tested it with
- gtk and lesstif.
-
-I use the second option mostly in conjunction with deactivating the first. Both commands
-have been added to the menu by means of (g)pcb-menu.res.in and are available as command
-line options as well.
-Caveats:
- - The HID API expects all HIDs to make a copy of the color string when setting a color.
- - The function that lightens up a color could be improved.
- - I used it for a while, but after porting it from my local fork, it probably needs
- more testing.
