Deleting internal layers

autodeskguest

I'm modifying a previous design into something different.  The original

design was laid out on a 4-layer board, but I'd like to lay out the new one

on a 2-layer board.  I've set things up correctly on the layers tab in DRC,

but the Layers panel in the board designer still shows the internal layers,

and it gives me an error when I try to delete them ("Can't delete internal

layers.").  Is there a way around this? If push comes to shove, is it safe

to just ignore the internal layers while I'm routing? 

 

The reason I'm not creating a new design from scratch is that there's a

power supply section in the original design that was kind of tricky to

route, so I'd like to preserve it.  Everything else is just airwires I'll

have to re-route.  Thanks.

 

I'm running v4.16 on Win7 x64.

    Compared to a new license, that's a very attractive price, but I'm having

    trouble finding out what's better about the 7.7 vs. 4.16, so I can't tell

    if it's actually worth it.

     

     

    Hi Karl,

     

    Here is my best shot at summarizing what has been added to EAGLE since

    V4.16. If I miss anything, hopefully other users will chime in.

     

    Differential Pair Routing with Length equalization

    XML File format for easy version control

    Assembly Variants

    Custom context menu entries

    2 sheets in the Freeware version

    Table of contents view in the library editor

    Arbitrary pad shapes in the library editor

    The ability to assign multiple pads to a single pin in the library

    Attributes(Maybe was in V4 I don't quite remember)

    Follow-me router

    Schematic Hierarchy(still needs work, but the future is bright)

    Infinite undo/redo list within a session

    Better resolution on the CAM processor by default

    Dimension tool

    Import existing EAGLE drawings into new ones (Design Reuse)

    Sheet thumbnails in the Schematic

    Design previews in the EAGLE control panel

    ACCEL-ASCII Import

    Bridges to LTSpice and PCBSim

    Net names show up on traces and pads in the layout editor

     

    This is everything I have off the top of my head, however I'm sure I

    missed a few things.

     

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

     

    Best Regards,

    Jorge Garcia
