hi,

Andy Peters said:
For example, my preference is to create a discrete symbol for every part. Each symbol includes a footprint as well a complete vendor part number, so I can generate a BOM directly from the schematic without needing to go through an external database lookup step.

Could you explain it, please? I use PCAD and do not see any problems generating Bill Of Materials list. What do you mean with "an external database lookup step"?


Yeah, this means I have a resistor library with a hundred resistors, and I place on the schematic the particular value I want, but it's not as big an issue as you might think. Creating a new symbol for a 4.99k 0805 1% resistor is as simple as copying the symbol from the 4.75k 0805 1% resistor and changing the value and the vendor part number.

Well, for example, I have only one SMD resistor (component RES_0805) in my library then I place it on schematic two times and set value of one to 1K0 and 10K for other one. Then I generate BOM file:

======================================================================

Count  ComponentName   RefDes          PatternName     Value          
------ --------------- --------------- --------------- ---------------

     1 RES_0805        R1              CC0805          1K0            
     1 RES_0805        R2              CC0805          10K
Could you explain, why do you make "a resistor library with a hundred resistors", please? I cannot catch an idea.

Thanks,
Oleg
