3D entities read
3DFACE, polyface meshes, polygon meshes, and AutoCAD MESH objects all import. Points are welded so a sheet of faces becomes one clean surface.
DXF + MechaPaint
AutoCAD's exchange format, read natively. Drop a .dxf on MechaPaint and the 3D geometry opens, one paintable part per layer.
WHY MECHAPAINT
CAD geometry straight into a painter
I wrote a DXF reader into MechaPaint so drawings from AutoCAD, BricsCAD, LibreCAD, SketchUp, and every CAD tool that exports DXF open with no plugin and no conversion. The 3D entities come in at the drawing's units, blocks are placed where their inserts put them, and each layer is its own part ready for materials.
Blocks and arrays placed
INSERT references, nested blocks, and rectangular arrays are expanded with their rotation and scale, so the drawing looks the way it does in CAD.
Units respected
Inches, feet, millimeters, or meters, read from the drawing header, so the model arrives at its true size for measuring and export.
Layers are paint regions
Hull, deck, and glass on separate layers become separate parts with their own layer stacks and materials.
PIPELINE
DXF to painted model
01
Open the .dxf
Drag an ASCII DXF onto MechaPaint.
02
Rebuild UVs
One click gives the CAD geometry a clean layout for painting.
03
Paint and export
Fill materials per layer, then export FBX, GLB, OBJ, or STL.
CAD in, textured model out.
