Preparing models
Materials and thicknesses
Assign materials in Onshape so DXF Exporter groups your download by sheet stock — material name plus measured thickness.
Sheet fabrication is organised by stock — 18mm birch plywood, 12mm birch plywood, 9mm MDF, 4mm acrylic, and so on. DXF Exporter follows the same convention: every download groups DXF files into folders named from each part’s material and thickness.
The material name comes from the Onshape material assigned to the part — what you see in the Material dialog, not a separate app setting. Thickness is measured from the part geometry during validation and added to that name. A part assigned Birch Plywood at 18mm thick lands in an 18mm Birch Plywood folder; the same material at 12mm thick is a separate folder. Different materials, or the same material at different thicknesses, never share a folder.
Parts with no material assigned still export — they are grouped under a default stock name. For what else is in the download, see Download package contents.
Assign a material in Onshape
Right-click a part in the Feature list or graphics area and choose Assign material. Pick a material from a library, or use the Custom tab to enter a one-off name and properties for that part. You can assign the same material to several parts at once by selecting them first.
