There is an addon server available (from either RSI or the Protel website) which
can be used to edit sizes of holes
to different values. This may be useful for what you are trying to do.

Alexandre,

set the scope to check only the holes of certain size or certain net, not the
whole board.

Subject: [PEDA] Hole Size Constraint


I want to set some rules in the "Hole Size Constraint" to specify the
drill bits available from APCircuit.  I've set the following constraint
:

Name            Scope            Min        Max
Drill 42mil    Board             42mil        42mil
Drill 28mil    Board             28mil        28mil
Drill 35mil    Board             35mil        35mil


When I run the DRC, I get the following rule violations:



Processing Rule : Hole Size Constraint (Min=42mil) (Max=42mil) (On the
board )
   Violation         Pad J1-25(49796mil,53700mil)  MultiLayer  Actual
Hole Size = 35mil
   Violation         Pad J1-24(49905mil,53700mil)  MultiLayer  Actual
Hole Size = 35mil
   Violation         Pad J1-23(50014mil,53700mil)  MultiLayer  Actual
Hole Size = 35mil
   Violation         Pad J1-22(50123mil,53700mil)  MultiLayer  Actual
Hole Size = 35mil
...
   Violation         Via (52895mil,51705mil) TopLayer to BottomLayer
Actual Hole Size = 28mil
   Violation         Via (53060mil,52280mil) TopLayer to BottomLayer
Actual Hole Size = 28mil
   Violation         Via (50621mil,53040mil) TopLayer to BottomLayer
Actual Hole Size = 28mil
   Violation         Via (50698mil,53040mil) TopLayer to BottomLayer
Actual Hole Size = 28mil
...

Processing Rule : Hole Size Constraint (Min=35mil) (Max=35mil) (On the
board )
Rule Violations :0

Processing Rule : Hole Size Constraint (Min=28mil) (Max=28mil) (On the
board )
Rule Violations :0


Depending on the order that I entered my constraint, Protel change the
violation (ex : Violation on the 35mil hole size constraint for all
holes set to 28mil).


Could you tell me if this issue has already been addressed on the
forum.  If not, I would like to know if someone already did this and
how.

I know that I can use the "Hole Size Editor" to check this by hand, but
I would like to be able to use the DRC to check that.  Isn't the DRC job
to check for manufacturing errors??

Thank you

Alexandre Desnoyers
