What is a 3DMK file?
Model design created by 123D Make, a program used for turning 3D models into cutout plans; stores a 3D model that is used to generate cutout instructions for building the model with paper, wood, or other materials; used for DIY (do-it-yourself) home model construction projects and can be shared with other users online through the 123D gallery.
123D Make can generate various instructions from four construction techniques: stacked slices, interlocked slides, curve, or radial slices.
