As of now all my via's are NOT covered with solder mask.
Hoe can I cover all via's with solder mask?

Hello Harry,
Here is the information under FAQ on the CadSoft website...
EAGLE generates by default a solder stop mask for each Via (also for Pads
and SMDs, of course). This means the Via is free of coating material. The
solder stop mask is drawn automatically in the layers 29, tStop, for the top
side and 30, bStop, for the bottom side. The size of the solder stop mask
can be determined in the Design Rule's Mask settings. See the values for
Stop. By default the value is fixed to 4 mils. Minimum and Maximum are set
to the same values therefore.
If you want to have a diameter-dependent mask you could also define a
certain percentage. The resulting value can be limited by a minimum and a
maximum.
In order to have vias coated, EAGLE allows you to set the solder stop Limit
in the Design Rules' Mask tab. Here you can define a value which is
dependent on the drill diameter of the via. Let's assume you would like to
set the Limit to 0.012 inch. Now all vias in the layout up to a drill
diameter of 0.012 inch will be covered with coating material. All those vias
that have bigger drills will stay uncovered.
In case you want to have some smaller drilled vias uncovered, you have the
possibility to select vias out of those that are covered in order to uncover
them. This can be done with the command CHANGE STOP ON | OFF in the Layout
Editor. This also works for groups.
By the way: It is allowed to draw areas that should remain free of coating
material in the tStop/bStop layers directly. But it is not possible to
delete certain automatically generated solder stop symbols there. You have
to deal with Limit and CHANGE STOP ON | OFF instead.

This also doesn't work as I expected to be.
My via's have a size of 0.019685inch.
My minimum drill size = 0.5 mm
In the Mask tab I enter 0,5 mm in the Limit box and then click on Apply but
nothing changes.
In layer 29 and 30 still the solder stop masks are visible.
