Hi Bill,

Looking at the MegaCut 3d specs it writes; Supported file formats: plt, dxf, G-Codes, RAW 3D, bmp. This means you'll have to go through a second step to get your model into MegaCut.

Even though it says dxf it doesn't specify if that's 2d lines, arcs and splines or 3d mesh data, MoI does export dxf but only 2d lines, arcs and splines. You'll have to find out if the MegaCut dxf is 3d mesh data first either way it looks like you'll have go through another program like Blender which is free http://www.blender.org/ and supports dxf meshes and RAW however before you try and export in RAW 3D, which by the way looks like the only 3d mesh data MegaCut will accept, I'm not sure but you might have to install a script to get the RAW 3D option.

Cheers
