[udig-devel] copy/move/rotate groups of polygons

[Jesse Eichar]

Hi Kurt,

There is support for moving a single geometry but not to rotate or to  
move a collection of geometries.

Here is one way you might accomplish this:

Create a new tool that is similar to the Edit tool but add an  
activation behaviour that puts all the selected features on the edit  
blackboard
Create a behaviour similar to the MoveGeometryBehaviour that moves all  
the geometries on the edit blackboard
Optionally add a rotation behaviour to the tool

The work flow for this would be:

Activate the selection tool (not edit tool) select some features,  
copy, paste, activate your tool, move features to new location.

Another idea might be to create a new paste operation that pastes the  
features on the edit blackboard at the location of the mouse pointer  
and then you would use a tool with the move all geoms and rotate  
behaviours to fine tune the position.
