The export to DSN produces a usable file for Freerouting, but the scale is 10X too small.
Whether the EasyEDA canvas is in mm or mil, the export is in mil, with 10x too small boundary and locations.
All features (clearance matrix, rules, padstacks, vias, etc) are 10x scaled down too.
Note that the \<resolution_descriptor> must meet the following:
> _If the smallest dimension in a design has four digits to the right of the decimal point (such as
> 0.0001), the must have at least five zeros as the least significant
> digits (such as 100000). Otherwise, a roundoff error can occur in representing the smallest
> dimension. For example, a circle with a diameter of 4.2221 has a radius of 2.11105 and
> requires a fifth decimal place to avoid roundoff._
The _proportions_ are all correct in Freerouting, but (for example) default trace width rule of 8mils -> 0.8 mils in FR.
Importing the SES file actually re-scales locations back up correctly, but feature sizes keep the 10x downscaling.
Also, inner layer conduction areas are not exported.
Exporting everything as one component u1 is a little odd, but functionally works if you don't want to move components around.
This will be a fantastic feature when DSN / SES export/import works!
