SO GREAT !! Thanks a lot for implementing that.<br>This is really powerful and usable.<br>Some CAD systems provide also the possibility to snap, for example, at the intersections of lines (without having a real point) or in the middle of circle. Usually, the cursor will change depending of the type of snapping. But this is of course more than a nice to have.<br>
Thanks again !<br>Cédric<br><br><br><div class="gmail_quote">On Thu, Jan 13, 2011 at 3:26 PM, Eric Lemoine <span dir="ltr"><<a href="mailto:eric.lemoine@camptocamp.com">eric.lemoine@camptocamp.com</a>></span> wrote:<br>

</div>Thanks for explaining.<br>
<br>
Some of us here at Camptocamp have discussed this a bit further, and<br>
we've come up with a potential solution to this issue, where the first<br>
point to be laid down is drawn as the soon as the control is active<br>
(or the previous feature is finalized).<br>
<br>
See the demo on<br>
<<a href="http://dev.openlayers.org/sandbox/elemoine/draw-feature/examples/snapping.html" target="_blank">http://dev.openlayers.org/sandbox/elemoine/draw-feature/examples/snapping.html</a>>.<br>
You should have a point following the mouse as soon as the draw tool<br>
is made active in the toolbar.<br>
<br>
Cheers,<br>
