What is an .3DMK file?

.3DMK is 123D Make Project 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.

NOTE: Autodesk 123D Make has been discontinued and is no longer available for download.
