Dear All,
An overwhelming response to my masks problem has given two
main options:
The true masking solution:
In a new layer (or cosmetic) draw a polygon over the area you wish
to view, (you may already have a polygon!) then draw
a bigger one over the area you wish to mask. Select the larger area
and...
Objects - set target on the larger area.
select the smaller area using ctrl + left mouse click
then...
Objects - erase.
That will give you a single polygon with a hole in the middle the
shape of your original polygon. Then save this doughnut polygon to
a separate layer and move it on top of everything else thus
masking external data and letting what you wish to see shine
through!!
The Clipping version:
Select the polygon you have e.g. a district boundary with LandLine
data overlaid. Select the district polygon: Map Clip Region, this
will clip all of the surrounding data and show only that which falls
within the polygon. N.B. - Apparently this is only a display function,
you are not actually permanently clipping all your data...
Thanks again everyone who replied! The solutions solved my
problem, good luck to those who inquired for their own purposes!!
