What is a Edit Tool?¶

Edit tools are another sub-type of tools, however they do not (yet) have their own extension point. Instead they are extensions of the org.locationtech.udig.project.ui.tool extension point. Because there are a large number of editing tools that can be created an many of them have similar functionality there is a little framework associated with edit tools development. The design and more detailed discussion of the edit tool framework can be found at Edit Tools
