Hi Jody,

Thank you for quick response.  Unfortunately, I'm still unable to  
accomplish the multi-feature move; comments follow below:

Quoting Jody Garnett <jody.garnett@xxxxxxxxx>:

That is the crux of the matter -- exactly how do you edit multiple  
features?  You cannot hold down shift, or ctrl+shift, or alt+ctrl, or  
any other combination I can find to select multiple features.   
Additionally, I cannot see how to "draw a box" with the edit feature  
tool.  If I have a feature selected, I can then draw a box, but that  
doesn't select more features; in fact, nothing changes.

An UnformattableObjectException raises when I try that:
org.geotools.referencing.wkt.UnformattableObjectException: Invalid WKT format.

org.geotools.data.shapefile.ShapefileDataStore.createSchema(ShapefileDataStore.java:833)

However, I can try the reshape on a scratch layer.

move doesn't exist, as I get a vague error about MoveFunction not  
existing.  It seems like functions for scaling, rotating, and  
translating should exist.

I am currently unable to access any user documentation on  
udig.refractions.net, as the refractions.net web server is throwing a  
Proxy Error:
---
Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /confluence/display/EN/Home.

Reason: Error reading from remote server

Apache/2.0.53 (Fedora) Server at udig.refractions.net Port 80
---

So, I can't check if there's a function out there to translate.

Any additional comments or ideas on how to move multiple features as a  
group would be greatly appreciated!

Regards,
bishop
