Assembly Variant Part Attribute

if you assign the the value via technology, you can also assign the

related manufacturer/vendor information as properties of that

technology.

 

Instead of changing value & manufacturer/vendor data separately, just

change the technology and you are done.

Yes good point, that does work but I found it could be quite unwieldy to

deal with setting values this way if for example you want to do this for

say the entire E24 range of resistance values (let alone E48/E96/E192) in

packages from 0201 through to 1812 and it became a total mess for

capacitors. That's a heck of a lot of work to do to create that library and

to select the value you want requires searching and/or scrolling so takes

longer. But the plus side is, if you know your library is right then you

know that when you select a value in this way, the corresponding attributes

for internal / manufacture part numbers etc will get updated correctly

which ensures things stay consistent.

I've not got a good solution for managing keeping additional properties

updated other than the above approach using technologies. Other tools I

have used have been able to hook into an external database via ODBC to

provide a searchable library of parts and the attributes get populated from

the database when selected but this is part of a totally different

discussion about Eagle libraries and library management in general rather

than this thread relating specifically to variants.

I think the enhancements suggested to the way variants work are still valid

despite there being this possibility of a work around and they would make

variants more intuitive to use and more flexible. I guess we'll have to

wait and see what happens now!
