EAGLE v8.0 Slice Command   Doesn't Work on Group or Fr om Command Line

completely functional from the command line.

 

In the many, many schematics and boards I've done this mode of operation

(select function first then apply to object or group) has proven to be the

most efficient method. And if I have to start to remember which commands

work in which mode then that's going to start to become more and more

confusing as new commands are added.

 

The beauty of EAGLE commands is the orthogonality and that everything can

be scripted by using the command line.

Hi James,

I think you've misunderstood how the command works. You don't have to

select the traces in order to slice them.

Here's the basic workflow:

1. Click on the Slice icon.

2. Now you are going to define a slice line that runs through the traces

you wish to slice. Left click the first point of the line.

3. You'll notice that now you have line going from that point to your

mouse cursor. Left-click to define the second point.

4. Voila, you'll notice that the traces have been sliced following the

line you defined.

On the command line you can enter specific points for the slicing line

as well as how wide the gap should be.

Let me know if there's anything else I can do for you.

Best Regards,

Jorge Garcia

I believe James' question boils down to why can't I execute 'SLICE (x1 y1) (x2 y2) '?

Eric has it mostly right.  I understand how the command works as is.  I had

two points:

1)  How the command works is NOT orthogonal with how every other command

in EAGLE works.  Pick function, apply to object or group with the group

having been defined by the preceeding group command.  If I try to do that

it doesn't work and it should.  You've provided a different method which is

fine, but it should work in the old way too to keep orthoganlity.

The reason for doing this is learning curve.  If commands use different

modes of operation then I also have to remember which command works in

which mode.  This is bad for usability.  Orthogonality is good.  If you

want to have a special, optimized mode (like group now does) that is great

and power-users like me will use it.  But things should also always work

in the EAGLE way to help new users.

2)  As the splice command is implemented you can't use it in a script.  If

this precedent is followed then scripting loses most of its power as new,

powerful commands are added but not usable in scripts.

It seems like some good functionality was added but by product managers who

didn't fully understand the actual power in why EAGLE was implemented in

the way it was.

Cheers,

James
