I'm a new user of DipTrace and apparently do not understand the parameters for setting up a via style. In my design, I have the Default via style:

Outer Diameter: 0.6 mm
Hole Diameter: 0.4 mm

All the trace vias in my design show errors, all with errors similar to:

Copper pour - GND (Via) (Gap=-0.548 mm: Rule=0.152mm)

Does "Gap" mean the minimum distance from any point on the exterior boundary of the via to another copper area with a differing net name?
If not what does Gap mean? I want to know this so I can understand how to avoid this error in future. An illustration of what PCB layout
looks for to generate this error would be most helpful. It would also be useful to know where one controls the Gap setting.
It appears to be Verification/DesignRules (2nd column (via) at 5th row (Copper)). I would think that if the current net is, say GND, and
the destination Copper Pour is the current net (i.e. GND) then the clearance rule (i.e. "Gap") would not apply. Could someone
explain may misunderstanding?
Thanks!
