[PCB_FORUM] Re: same net rules

There are seperate DRC settings for via to SMT pad, via to via, and via to Thru hole. 

Does this not handle what you are asking for ?

Hi all,

I think I do understand the question since I also miss such feature.

Problem stated:
- to not to have Via too close to SMD pin

Partial Solution:
- enable same net DRC (problem is that it checks all other rules and often creates many unwanted DRCs) 

Other possibility
- set a rule for "Solder mask to Solder mask" spacing assuming that Vias are not covered (problem is that this is one global rule for a whole design) 

regards,
Robert

Is there no way in Allegro to have the same net rules apply only to
certain
rules?  The one I always need is via to smd pin, but I would not want
all
the rest of the rules to have same net application.
