Hi,

My question was not very clear I guess.
I have a layer with parcels.
I have an other layer with parcels that are suitable as building site.
When I draw features of this layer I want to snap to the parcels layer. I can 
do this with automatic tracing.
Every couple of years the parcels shape change, so I have to manualy adjust the 
parcels that are suited as building site.
I use the node tool, but I want to visualize the new vertexes of the underlying 
parcels features.
I’m also looking for the same functionality as the ‘replace sketch’ menu item 
that exists in ArcMap. That function allows to create new features by taking 
over the shape of the underlying feature of another layer.

Hi,
Using the automatic 
tracing<http://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#automatic-tracing>
 option, you wouldn't need to visualize them. QGIS will snap to vertices as you 
move the mouse close to them.

Hi Reginald,

See Settings --> Options --> Tabs "Digitizing". Perhaps for some reasons the 
markes are set to "none".

You can also choose to display markers only for selected polygons.

I don't know about a shortcut to toggle visibility of the markers - sounds 
useful.

Hi,

Is there a similar way as in ArcMap to visualize the vertexes of a polygon? In 
ArcMap, by pressing ‘v’ I can see the vertexes during an edit session, so I 
know where to snap to.
How can I visualize the vertexes in QGIS during an edit session?
