Lego Digital Designer
 

I've found that the LDD very useful, and it would be handy to be able to LDD files (.LXF) in RW.

Here is LDD.

I realise that it won't be high on the list of priorities, :) , but it would be nice. :D

You should be able to add them to Realm Works as a "Foreign Object" type. It is under the More/Advanced Types menu for adding snippets.

Indeed I can, thanks davidp! :D

Zaphod, what do you use LDD for?

Well, I'm going to use the Lego minifigures as miniatures, (at the scale of 4 Lego blocks to 5 feet, that's 1 1/4 inches per square on an home made battlemap,) and use LDD to design sets and vehicles for my games. Not that I will be able to buy much, but I can take a screenshot of things so the players can see.
