It's bad news. With LDD, you could have a standarized build with no build errors and then export to a building instruction.

Reading the discussions on the eurobricks/brickset forums, some users are (ofcourse) going to take the iniative to make a petition or even better, start making parts on their own. But the complexity of parts has increased and collision ( a difficult term in building these applications) is probably going to cause a lot of issues after some time.

I understand the deciseon to close down LDD, it's being an oldie among the building platforms. Go have a look at the textures. 😛 The chance that LEGO will come up with some new - as suggested on brickset - might be what the plan will be. LEGO Worlds is still based on LDD and it's coming out soon but I can imagine that this will only contain standard bricks to use as more complex bricks could cause issues. LEGO Universe (the game we all still have in mind) had also the LDD feelign and was also based upon this concept. But this had a good opportunity, you could just walk through your built model, a high +. Chima Online (also already discontinued) was also based on LDD, not many do know that, but the buildings appearing in the game were built up on in-game from a LDD file!

So, I'm thinking that they just sad goodbye for now, but will come out with something new.

EDIT: "My underground work to destroy LDD finally worked! Just kidding I'm sorry for the users. But hey come try mecabricks!"

Ahahahaha I love Evil Scrubs 😂 😂 😂

Another message got sent out this afternoon:

"Dear Ambassadors, I hope this will help clarify a bit of the confusion and misunderstanding from our end regarding LDD. TLG will remain committed to digital building going forward, in regards to LDD, this means that we will continue to support the current functionality. We will not be doing automatic updates on elements, however elements will continue to be added from time to time. Unfortunately we cannot ensure that all elements are made available. I can see that the message has spread widely in the community since Kevin’s statement and I hope that you will assist us in spreading this message as well. Thank you! "
