I recently got to play with Lego because my daughter, who is five, got interested in it. There are attractive boxes for girls, it's called Lego Friends and the figures are a bit more life like.
Nice! ;)
If you need user-friendly CAD for creating digital Lego models (for planning builds before build it) try LeoCAD app with LDraw Parts Library.[0,1,2]

Then you could use this XML-file for order all needed pieces.[1]
When we exported our models to another Lego cad program, the new program tore our models apart, finding issues with almost every piece (due to them being partly inside each other or other things).
My friend is an engineer who is very used to CAD software, but struggled immensely with the features provided in the package. This pains me because I was so excited about it being Open Source.
Edit because my post sounded confrontational: I desperately would appreciate tips as to what we may have done wrong, our struggles in placing flowers on a baseplate compared to the models LeoCAD claims to have produced means we must have been messing up really bad.
