Tool to combine/reduce the number of parts?

[Michael Horvath]

In LDDMC under "Settings" -> "Export" you can set it to substitute parts according to your "part_types.txt" file. Enabling this will cause the generated LDraw file to use larger plates when possible.

If you really want to just build with 4x4 plates, then I can add that as an option to "construction techniques" as well.

You can also create the mosaic with 1x1 plates and simply use 4x4 plates when building. It all depends on your use case.

Wow, I did not know LDDMC was configurable! I will take a look at "part_types.txt", thanks. What I really want is for the program to always use the largest plates possible.
