Quoting David Bridges
I have seen in your construction photos a list of parts needed for each model's construction. It looks like Excel. Did you count out each type of bricks you needed and create the list youself?
Glad you asked. Yes, it is Excel and that's how I make all my parts lists. I don't count pieces individually on LDD, though. For a high quantity part such as the 1x1 clear plates in the Sears, I isolate them, delete the rest of the building, then generate a building guide. Then I use the option "generate html building guide". This gives you an exact count of the pieces. Then I go back to LDD and undo the deletion and delete the part I just got the count of after I type it into excel. Then once I'm done I make sure not to save the LDD file because then all the pieces I deleted while making the parts list would be gone.
