Hi,<br>
In Symbol Setting you can specify an attribute field to set the <b>size</b>
of the symbol. (click right-most icon [yellow in this image])<br>
Maybe fiddle with this to see if you can achieve what you need.<br>
<br>
Good luck and kind regards,<br>
Zoltan<br>

<br>
<br>
My requirement is to draw a few circles on the map but with radii
that I can vary quickly. The circles need to be changed
frequently for comparative purposes.
<br>
<br>
The radius could be obtained from a value in the attribute table
or, better still, from an on-screen dialog box.
<br>
<br>
Would this be possible? Thanks very much…
