"Flip View" button

When routing the back of a board, it would be really nice to be able to

flip the view to see the back of the board as it really is.

 

It would be extremely useful when debugging a board, as it's really painful

to find a signal in eagle, then mentally flip it to find it on the physical

board.

 

It would also be useful for checking text layout on the back of the board.

Mentally flipping text is a bit of a pain, and almost impossible when

you're trying to evaluate its aesthetic appeal. Yes, I do consider

aesthetics important in PCB design!

 

I know I can print out the board mirrored, or group-then-mirror, and

various other hacks, but if this button existed, I'd click it every minute

or so when routing a complex design.

 

In fact, I'd prefer the board view to immediately mirror when I changed

routing layer to add a via! Other people probably wouldn't, so this would

have to be an option that defaulted to "off".

 

I've been using eagle for ten years, always wanting this feature, but only

just realised there was a suggestions forum!

 

gEDA, Orcad, Altium Designer, and probably others support this so I can't

be alone in desiring this feature! (see

http://wiki.altium.com/display/ADOH/AltiumDesignerViewer-ViewingPCBDocuments#AltiumDesignerViewer-ViewingPCBDocuments-FlippingtheBoard

for example)

the only thing I would add is that it should be very clear that you are

in flipped view, not requiring checking coordinates direction, pushing

buttons, issuing commands. this should go without saying, but just to be

sure, I'm saying it!

I have just finished a board that is circle shape and almost symmetrical

layout, what a nightmare if I don't know which side I'm looking at, it's

hard to keep it straight even without flipping.

Do you have any particular idea on how this could be made "very clear"?

I guess any small icon indicating this will be overlooked, and a thick

"yellow/black" border around the draw window indicating "Caution - you're

in flip mode!" will be overkill...

2D/3D CAD programs often display a small overlay at the lower left part

of the window, showing a coordinate cross with all available axis

directions.

In a drill program of my own invention, I use the attached pictures

(plus others) to indicate the current view:

  1. "top0" shows the view at the top layer with no rotation

  2. "bottom90" shows the view at the bottom layer with additional

     90 degrees rotation.

And yes, since the display of any vector objects needs matrix

manipulations, anyway, it would be an additional bonus if one could

ROTATE the view. Therefore, I propose the following:

  3. Add BOTH mirror and rotation (in 90deg steps) to the VIEW.

  4. In case neither rotation nor mirroring is selected, do not

     display any additional overlay.

  5. In case the view matrix is not "identity", display the small

     overlay the following way:

  6. Mirrored view: Blue "B", non-mirrored view: Red "T",

     plus the current direction of both axis.

  7. Expand the WINDOW command to make use of the standard

     rotation/mirror syntax used for MOVE etc., so that "MR90"

     can be used.

Indeed, this is the widest used solution, and I tend to agree with the idea

of replacing the crosshair in the origin with something like in the attached

image. Mirroring the board will change the X arrow to the other direction.
