Hi Steven

Try this

First you select the main object,  then you write this in the MapBasic

Dim MainObj as object
Fetch first from selection
MainObj = Selection.obj
Select * from ParcelsTab where AreaOverlap(obj, MainObj) > 0

Note this:
all your parcels has to be closed objects, and if you have topological
errors in your object you will get and error

VedrÝrende:    MI Search for object within an object

Could you please help I'm trying to select all the parcels / objects
that are within or partly within a given object.
The within operater only selects those parcels that have their centroid
within the object and I can't use intersects as this gives all the
adjoining parcels that are not relevant, is there another function that
will select any parcels/objects thare are within or partially within the
main object.
