Constraint set up for delta and tolerance

jemarods over 12 years ago

Hi all,

What is the difference of setting up a delta of 0 , tolerance of 50.... (so 0:50)

with

no delta, tolerance of 100...... (so :100)

since in my case, a target appears if a delta is used.

follow up question:, how does constraint manager identifies a target net....?

Thanks in advance!!
