Forcing grid / angle alignment

When I'm moving a PCB trace (which had previously been moved off the

primary grid), what is the simplest way to tell Eagle "put this trace back

on the primary grid"? Another time I've wanted to do this is when I ended

up needing to change to more aggressive design rules, and switched from a

10-mil primary grid to a 7-mil grid--new traces worked great, but

squeezing the existing ones closer together was a major nuisance.

Ctrl MOVE: move and snap the element on the current grid.

Similarly, when moving a trace, what is the easiest way to tell Eagle

"make this trace exactly 90 (or 45) degree aligned"?

SPLIT: break the wire in segments, you can choose the angle with the right

button of the mouse.

If there isn't an easy keystroke/mouse combo already defined, is there

some command sequence I could bind to a key?

Have a look for the "Help"

Thank you. I overlooked that one in the help.

SPLIT isn't quite what I want to do here, because even though the trace

I've split ends up with nice alignment, after that, I have to fix up the

rest

of what it's connected to by hand.

For example, what I'd like to do is move a corner (or a via) and tell

Eagle "keep everything connected here fit to the nearest 45-degree

angle", and have it make corresponding adjustments at the segments

they are connected to. I can do this all with SPLIT, but I'm trying to

reduce the amount of manual adjustment I need to do afterward.

Or maybe I'm just not using SPLIT correctly. That's quite possible,

since it still doesn't feel particularly natiural, and I'm never quite sure

what it will do.

i delete or unroute the old trace and lay a new one using the 45 angle

wire setting. yup, that's not much help either!

Get more used to EAGLE.

It depends on where you pick the wire segment.

For MOVE, each segment is divided into three parts. If you pick the

inner third, you move the complete segment. Picking the outer thirds

will let you move the endpoints (including attached vias and/or

neighbour segments).

For SPLIT, each segment is divided in two parts. The wire bend mode is

applied to the smaller part of the segment, you continue modifying the

track in direction of the longer part.

Play with these commands to get used to them. Once you are, they are

very powerful and perfectly predictable.

(I have assigned ROUTE, MOVE and SPLIT on function keys which makes

using them very fast.)
