How to get new components on the PCB ???

Former Member
Former Member over 13 years ago

I have a schematic (A) witch board (B) I want to fit exactly to the spot of the holes for some components from another schematic - therefor I have copied the BOARD from this other schematic to my project and want to use it as the board B.

 

Of cause I have to delete all the wiring and most of the components but LEAVE the components I want to fit to.

 

Now I have the problem when I switch to board, that the components from the schematic A is NOT to find at the board (B) - how can I some kind of "update", so that the components from A is to find on the board B ?

 

Best regards

    Eagle cannot do this simply.

    How you proceed will depend on the number of objects you wish to place

    precisely.

    If you wish to replicate the board outline, a few mounting holes and the

    accurate placement of a few parts then I would do it manually using Eagle to

    deliver the precision.

    Right now your schematic(A) and Board(B) are consistent. All your actions

    need to retain that consistency.

     

    Proceed, as you have, open a copy of the reference BOARD that has the

    positioning you wish to replicate, removing all items that are not required.

    Next we can use a ULP to get the details/positioning of the remaining

    objects. Unfortunately there is no ULP to do the whole job.

    Use the ULP export-board.ulp (download from cadsoft.- caution this is a v4

    ULP but we can use it here for our purposes) The Script file that it creates

    has all the information you require but you cannot just run that script for

    a number of reasons.

    If you ran the scr file 'as is' it would draw the board outline and any

    mounting holes. It would then attempt to ADD (new)  the parts to the board

    and will fail due to naming or library issues.

    You need to modify the script to MOVE the equivalent board(B) part (your

    part) to the same location

    Open up the script file in a text editor.

    Change the lines that start ADD

    (1) Change ADD to MOVE

    (2) Delete all the way up to the "("

    So a line like

    ADD 'D1' D0204-10@diode R180.000 (0.400 2.650);

    becomes

    MOVE 'D1' (0.400 2.650);

     

    Next change the part name ('D1' in the above example) to match the part name

    on your schematic(A) Board(B) so you move the correct part into position.

    Save the script file

    Open your project (schematic(A) Board(B))

    Delete the default board outline on Board(B)

    Run the script file in the Board(B) editor

     

    You should see the board outline, holes and part placement of BOARD

    You may have to manually ROTATE a part to get it correct.

    You may care to LOCK those elements so you don't inadvertently move them

    later.

     

    In future when making daughter boards (Arduino shields are another example)

    Start with / prepare a (seed) project you copy  to be your current

    project.This has your board outline and connection headers done first.  Then

    you continue to develop the schematic. Another approach is to make this

    headers/board outline a library part.

    It is easy to create Libraries from Schematic and Board file by using ULP:exp-project-lbr.ulp from ULP folder in the path of EAGLE installation.
