Hello Kent,

The simplest solution (I believe) is to make a copy of your points layer,
close all and then open your newly created copy. Make the layer editable.
Open the MapBasic window and issue the command:

update YourTable set obj = MBR(buffer(obj, 12, 10, "mi"))

Here you are changing each map objects to be a rectangle which contains 12
sided buffer (10 miles radius) from your points. This is a workaround for
Pro not having a "CreateRect()" function which would make the job simpler.

Note that if you create simple buffers with resolution 4, you will get
diamond shapes and not squares.

Subject: MI-L Creating square areas around centroids


I have a table of centroids and am looking for a way to turn each
centroid into a square region, approximately 10 miles aside, for the
purposes of thematically mapping it.
Any ideas?
