  • Dear people,

     

    I have downloaded EAGLE Version 5.11.0 for Linux, and use the Light Edition.

     

     

    My  problem with this program is that if I open the Script Window and  choose the delete-signals.scr file to ripup all signals on a board,  sometimes when I activate it it's not the traces and airwires in the layout that are deleted (as described) but it's all the parts that disappear.

    Very inconvenient, because I have to start all over positioning the parts and so.

     

    Could not find anywhere if this was a known bug, so I'm asking you.

    Hi Louis,

     

    never heard of this problem before......

    Well, looking into the script I can see that in a first step we remember the currently displayed layers.

    Then the script uses RIPUP for the signals and now only layer 19 will be displayed. Then GROUP

    DELETE to all visible airwires. Last step is to display the previously displayed layers again.

     

    Regarding the way the script works, I could imagine that, if the layers tOrigin and bOrigin are displayed

    before selecting the GROUP for deleting all objects, the parts will be deleted as well.

    But I can't think how this could happen. Could you please check the script file? Maybe there is a problem

    in it.

    The original looks like this:

     

    # Delete all signals in the layout

    #

    # This script is written for EAGLE 5 and removes all traces and airwires in the layout.

    # This script replaces the former DELETE SIGNALS command.

     

    DISPLAY = _current_layers_ @;

    DISPLAY ALL;

    RIPUP;

    DISPLAY NONE 19;

    GRID INCH;

    GROUP (-32 -32) (-32 32) (32 32) (32 -32);

    DELETE (>0 0);

    GRID LAST;

    DISPLAY _current_layers_;

    DISPLAY = _current_layers_;

     

    Regards,

    Richard

    Hi Louis,

     

    that's really odd...... Never had such a problem, but I will keep an eye on it and will do some testing.

    If there is any news, I will tell you.

    I checked the file and it's exactly like you wrote, see below:

     

     

    # Delete all signals in the layout

    #

    # This script is written for EAGLE 5 and removes all traces and airwires in the layout.

    # This script replaces the former DELETE SIGNALS command.

     

    DISPLAY = _current_layers_ @;

    DISPLAY ALL;

    RIPUP;

    DISPLAY NONE 19;

    GRID INCH;

    GROUP (-32 -32) (-32 32) (32 32) (32 -32);

    DELETE (>0 0);

    GRID LAST;

    DISPLAY _current_layers_;

    DISPLAY = _current_layers_;

     

     

    I found out that the chance of the script having the wrong result is bigger when I select it by dubble clicking it in the list, then when I select it via the OPEN button.

     

     

    Doesn't get us any further, hu?
