SMD pin to SMD pin DRC errors when adding teardrops

Maybe it's just me, but... I'll ask anyways. Why do you 'teardrop' your SMD pads? Over 30 years in the industry I've NEVER added teardrops to my SMD pins. Or any pins for that matter. Actually I've NEVER added teardrops to my vias either. I do have a note on the fabrication drawing that allows the fabricators to add them in highly-conjested (extra small traces/spaces) areas, but can't say any fabricator has. In my experience, the teardropping thingie comes from PADS, since it was so easy to add in PADS, but NEVER have I done it personally.

BTW - I've worked for a good number of companies too, and have never been asked to add them.

Just curious. Good day.

I get the impression that the group advocating teardrops is as big as the one that doesn't. When the latter group is double the size of the former I will stop using them!

In any case, I still wan't to figure out how to avoid a teardrop becoming a part of the pad during DRC.

They do not create DRCs for me. Can you post a design or Picture so we can see what's going on? 

No DRC errors without teardrops:

DRC errors with teardrops:

So in the Parameters for this is an Allow DRC box. Make sure that is unchecked BEFORE you run the command - see if that helps

I've tried that, but the result is simply no teardrops at all with the following message:

Enter selection point
last pick: 6.5290 60.8977
*WARNING: Can't create fillet at pad (6.4850 61.3400) on subclass TOP.
Computed fillet point lies inside pad boundary; required to be outside.

So try adjusting the parameters to smaller values to get the fillets added. The Allow DRC;s chekced is why you are getting DRC's. 

Pin to pin is set to 0.4mm: too large!. Does U140 have 0.4mm between pins? Seems not. Why so large value? Teradrops becomes part of pins so the behavior is OK
