I'm new to QGIS and am more familiar with MapInfo.

I've been playing around with QGIS to do some habitat mapping based on aerial photography and was wondering if there is a feature in QGIS which automatically draws a poly line or polygon whilst you move the cursor over the screen?

MapInfo has a handy feature called 'auto node' which does this by dropping nodes constantly as the cursor moves. It's useful as you can get very smooth lined polygons which are difficult to achieve if you have to click the mouse everytime to drop a node.

Can QGIS do this???

Thanks!

Steve

I think there is a "freehand" plugin you could give a try. – underdark♦ Jun 15 '12 at 18:14
@Under Out of curiosity, is there a central clearinghouse for QGIS add-ins? If so, we can create pointers to it from this site in various ways, such as through a meta thread or even our FAQ. That could help out a lot of people with questions like this one. – whuber♦ Jun 16 '12 at 12:14

@whuber In QGIS 1.8, there will be only one official plugin repo anymore: plugins.qgis.org/plugins. It will still be possible to add other, non-official ones (as far as I know). – underdark♦ Jun 16 '12 at 13:47

Underdark is right. You want the "Freehand Editing" Tool.

You don't need a plugin to get the MapInfo "add node" functionality, use the built in node tool and double click on a line segment near where you want to add a node. You can then move the new node to your exact location.

Better to read the question fully before responding with an answer. I would also recommend that you delete your above answer as it does not contribute. – Rayner Sep 27 '12 at 13:48
