[PCB_FORUM] Re: How do I include .dra file that contains my board outline in a DxD schematic?

A comment on Mechanical parts ...

They are well defined within Allegro and the Cadence tools, but many
downstream 3rd party translators (manufacturing, ICT, etc.) don't support
them and having them in the design will result in corrupt data (I've seen
this with both Fabmaster and Circuitcam).

I define any true "mechanical" parts that are added via schematic/netlist as
"package" symbols with a small pin as Jeff suggested.

Hth,

Hi Jeff,

I don't know.  It would now be an electrical item, instead of a mechanical
item.  That may cause an issue.  I should be able to do this without that.
People add non-electrical mounting holes to their schematics all the time,
and this should be the same thing.

Best Regards,

Austin
