Unable to delete certain object.

methias

Hi, I'm a new user of EAGLE. I'm trying to use EAGLE to design a PCB with Arduino Mega 2560 with some sensors. So the only thing I need for the design is the exact pin spacings and some elementary design with connectors.

 

So what I'm doing is I downloaded the EAGLE file from Arduino website, then I deleted any components that I do not want from the original file, only leaving the pad for the pin spacing. However, when I tried to delete an object from the top layer, which has some connections for it's microcontroller, no matter how I clicked the it, it wouldn't be deleted. Thus if I were to fabricate it, I would assume there would be connections that I do not want that will be printed(?)

 

Here's a capture of the layers I have, top layer is the one I want to remove.

    Hi Aaron,

     

    From the picture and the description its not immediately apparent to me what you are trying to delete. There are a couple of things to try off the top of my head, first check that you have the tOrigins layer turned on. Without tOrigins you can't select a component and therefore wont be able to delete it. Secondly check that it's not locked. Right click on the object and you get get a pop up context menu. If it says "unLock" in the menu then it is currently locked. If this is the case select the "unLock" option.

     

    I assume you have both the schematic AND the board file open together? If not then they will be out of sync and will mean back annotation wont work. The other thing which could be stopping you deleting is that components should be deleted from the schematic and not from the board. If this was the error you'd get a pop-up message telling you so which as you haven't said this is probably not the case.

     

    Best Regards,

    On reading back what I wrote and looking at what you are doing again, I actually now think you have just the board open and are deleting components directly from there. If so then this is probably not what you want to do. Re-download the files if you don't have an unedited copy of the board and open them both up and then delete what you don't want from the schematic. They will all be removed from the board by the automatic back annotation. Then switch to the board and tidy up and tracks and polygons which remain that you no longer need.
