How do I get unlimited color options on LDD? The title says it all.  I believe there is an unlimited option?  I just want to use it to make digital models.
To use the unlimited option of LDD, when you start the program and the little window pops up that lets you load or start building a set, click  the tab at the top of the window that says extended version and click add new!  then, you'll have unlimited brick and color selection.
