Creating your own components (rolling your own) can be an advantage. By
creating a different version of a component, with pins in more convenient
locations, a schematic can be cleaner and not as confusing.
Some notes, there are 2 types of libraries in DIPTRACE; Component libraies
for use in the schematic editor and Pattern libraires for use in pcb
layout.
The pattern libraries are the pcb footprints. the component libraries are
the schematic symbols, along with an "attached" footprint from the pattern
libraiy.The attached patern may be easily changed without creting a new
component.
The easies t way to use Diptrcce is to create the schematic, then allow
Diptrace to vassemble the footprints for the pcb. CRTL B does this. You can
create pcb's manually, but you either need toknow the name of the pattern or
select it from the library list that is open.
If you search for 4070 in the pcb program,you will come up empty, as the
patterns havve names like 14 pin DIp, etc
When you search for 4070 in the Schematic program, make sure the box All
Llibraires is checked and you will find almost a dozen schematic symbols
with 4070 in the name.
