Place from Library

Oppie

Any thoughts on being able to place devices to an open drawing from within

an open library?

I often make a library that is local to the project in order to not mess up

global footprints. Workaround for now is to add the location of the project

library to the library path specified in Options.

(version 7.6)

 

Thanks - Oppie

    That's how Eagle's lib system is almost a completely mess.   I look all

    around & see 350 different parts with a "TO220" geometry.  Are all of these

    "TO220" geometries exactly the same? How can you tell?  Are 29 of them

    style "A" , 200 of them style "B" & 121 of them style "C"...you can't tell

    since they are all called "TO220" & replicated all over different locations

    like ants.

     

    When designing a new part, who can tell how many different geometries are

    available in the system? How many different TO-92's are there?  Or maybe

    they are all the same... or all different?  Can't tell. 

     

    Eagle should prevent any part or geometry from having a duplicate name

    anywhere in the system. Each geometry should be usable without repeating it

    all over the place.  So if you define a    TO-3456, it is located in one

    place and can be used for as many different parts as you like. It is

    impossible by program enforcement to have a different TO-3456 anywhere

    else. So then there is no possible mistake as to what a TO-3456 really is.

    Say a different one IS needed for some reason, then it will have a

    different name, say, TO-3456-(A1)  (or some field that indicates

    variations).  Again that new variation can be used anywhere & can only be

    that exact style.

    Then all usable currently defined TO-3456 styles can be easily examined in

    one place for use in creating new parts.

     

    If desired, a part could be embedded into the particular design file,

    though not required.  Regardless, it must match the definition.  Should a

    part needs to differ in any respect, it requires a new number or variation.

    Then it will be easy to see what TO-220 styles are available for new design

    (in this example styles A, B, C exist)...rather than wondering if there are

    3 styles or 250 styles.  Cadsoft can maintain a master list of styles, so

    as others create any variations, they can simply be added to the types

    available.
