I'm new and hopefully in the right place, but I was trying to upload my LDD model and it will not generate a building guide. I've left it on over night, and tried re-booting, but after about an 1/16th of an inch progress, the dialog box just sits there. The model is quite large (26,000 bricks) - is there an LDD size or brick limitation? Any thoughts, ideas or help is most appreciated.
