Many thanks Andy and Martin,
Ok for your explanations Andy. However, I do not understand that
with as sophisticated software (not only Kicad), only one specific component
size is allowed, when it should be easy to foresee some. What a pity.
I have tried many, many possibilities with Kicad, and also the one exposed
by Martin. However, in my case, the connections with 1-pins (which may be
done with DRC inactive) generate track near pad error messages! If that is
not the case for you Martin, please give me an example.
As in most of the case my solution works well (problems occurs
only with GND zones), I think I will continue to deceive the DRC by doing
not really needed connections for the specific cases the DRC fails.
Perhaps the DRC check maybe changed to allow this few cases without problem
for a near future upgrade?
Thanks again,
Jean-Paul

Check your mod files, if you have two lines the same this will confuse
DRC, and I think by duplicating pads then is what you will create.
While doing things the way you are is fairly convenient, it's not really
the accepted way to do things. The module should be designed for a
specific component size.
One solution which is I admit, a bit of a bodge is to only use one pad,
but change it's shape and extend it to cover the range you want. The
disadvantage is that you will only have one drill point, rather than a
whole series of them.
The other way is to create a module with just a few pads, nothing else,
no numbers or whatever. Then place that alongside the pads of whatever
component you want the adapt. You will have to join the extra pads with a
track and connect them to the existing single pad of the component, but
at least DRC will be happy.
