After a lot of work I'm happy to present you: LEGO Part Manager - Version 1.0 This program helps you managing your currently displayed models and your other "ready to build" parts. It's able to calculate, which of your parts can be used in new builds. Description / How to use it If you start the program for the first time it will show you kind of a login page. There you need to enter your Rebrickable API Key (Go to your profile page, click settings and get your API Key) and User Hash, which you can generate here. After pressing the "Connect" button you can see all your set lists and part lists. All pre-selected lists are used in your normal Rebrickable build calculations. When clicking the "Download selected" button the program starts downloading all the selected items. This may take a while and in the mean time the program does not react fast, because it is busy... (Should change with the next versions.. ). When the download is complete, you can input all your displayed Sets / MOCs on the display tab. Please use the same MOC number as on Rebrickable, otherwise the program can't find the MOC. Take an example from the image and screenshot below... After downloading the sets, it will also show up the names. Now you can go to the build tap, where you can input the Set / MOC you want to build. After pressing "Calculate", it could look like so, then you have all the needed parts in your parts collection. If you are missing some parts, it looks similar to that. The file "NeededParts.csv" could be upload to Rebrickable as a private MOC, in order to see the part images or whatever... Current version: 1.0 - from 18.09.2016 (See change log below) Download program (.exe) here. Take a look into the source code here. You can compile your own version of this program on any operating system (Linux, Mac) since it's written completely in Pascal. Features
Imports set lists and part list from your Rebrickable account
Build calculations only with unused parts
Change the display / set lists always possible
Uses the Rebrickable .csv format for further use of the file
It's Open Source
Limitations / Bugs
No name based search, you need to input the correct set / MOC number
GUI needs some updates...
Works only with the Rebrickable API, no other part sources...
Also need to add more comments in the source code
Changelog Version 1.0 - 18.09.2016
Initial release I hope that at least a few people are going to use this program and providing ideas for further improvement. Thanks for reading, Dave
