I don't know of any complete tools that actually do this though. I know some people have done some research into directly converting LDD models directly into 3D mesh, by reverse engineering the file formats. If LDD does not know how to map a part to LDraw, it could also be missing.If you are using a piece that your LDraw program does not have in the library, it will be missing.This is probably your better option, but it also has some caveats: This means the mesh you get out may be missing some things you might expect.Ĭonvert to LDraw, and open in an LDraw compatible program that can export 3D meshes.LDD optimizes the drawing by removing the faces of parts that are not visible.There is some software which will attempt to capture 3D mesh from memory. So getting 3D mesh data out of LDD is tricky to say the least. LDraw files are similarly structured like the LXF files.The actual part data is stored in binary files inside the various LIF files. They only contain information on how to assemble the parts. LDD won't get any new features any time soon, as it is no longer being updated.LEGO Digital Designer cannot do 3D printing.
