Cost of different courtyard elements for the closed outline and DRC algorithms
Right now we have a few contributions for the library that use arcs
quite extensively on the courtyard layer.
I would therefore like a bit of input.
Are arc generally more expensive than lines?
Is there a difference if the arc is a multiple of 90 degree compared to
any other angle.
Is there a difference if the endpoints of two neighboring endpoints meed
exactly vs they being within the tolerance range for counting as a
closed outline (If i remember correctly then the tolerance was 0.01mm. I
assume this is the radius of the tolerance circle.)
Regarding tolerance: How stable will the currently chosen value be? (If
we allow arcs on the courtyard layer then we will need to fix a
tolerance in the KLC. This is especially the case for arcs that are not
