Instruction making rant

[Daniel R]

Where all users sacrifice their free time and make everything free of charge.

Certainly. I understand this and do not ask anyone to implement some changes for me. I am sorry if I have sounded this way.
Nevertheless I personally would rather spend my free time on improving this software than doing something utterly meaningless such as waiting for LPub to display new page, correcting wrong callout arrows or moving parts manually with buffer exchange.

I'm currently drawing a Technic MOC with about 14,000 parts, (yes 14 thousand)

That is very cool! Do you use LPub3D to make callout arrows? What is your typical wait time to display next page?

And I still believe that the MOC is buildable.

That may be true, but the question is not how many times BUFEXCHG is unavoidable, but how many times you would like to use it because it is appropriate. For example, how many times it is used in a official instruction. And the answer, for example for the beginning of 42082 instruction, is that there are more buffer exchanges than pages.

Moreover, I think we limit ourselves and change the way we produce instructions due to technical difficulty of some commands. At least I do. So I think I would use it much more often if it was an easier process.
