This is already possible with a few steps in MapInfo. I don't think you can
make it much simpler by writing a tool.
1) Make layer editable
2) Select the region
3) Objects > Set Target (ctrl T)
4) Draw "hole"
5) Select "hole"
6) Objects > Erase
Done.
Kind regards

Subject: [MI-L] Make a whole in a region object
Can anyone assist.
I am wanting to develop a simple tool for a user which will essentialy
make a hole in a region object.
For example.
We have a region object which depicts an area of land burnt by fire.
Within that region there are small pockets which were not burnt. We would
like to be able to draw in those unburnt portions into the existing
region.
Essentially the user would draw a small area within the existing region
which would then be erased from that region making a hole in it. (If this
makes Sense).
Can anyone make a suggestion on what road I would best take to acheive
this???
In anticipation - Thanks
