[LSC] File Format Restrictions for Official Parts

[Michael Heidemann]

Can somebody inform me about the angle according our new calculation 
based on the old -det and -dist rules?

I think we have had a good agreement over the past with the two values 
of -det 0.01 and -dist 0.1.
If we had a line that just fulfill this values, what will be the angle 
with our new calculation?
It should be a quad that is about 50 to 100 LDU square I think.

I mention this, because I want to avoid that we are too restrictive with 
our new rules.
