Custom parts
STEP for CNC solids. DXF for laser profiles. STEP, STL, or 3MF for printing. PDF for drawing requirements.
CNC needs a solid model
Use STEP or STP with a single solid body for the CNC quote. STEP retains CAD surfaces and solid geometry instead of approximating everything with triangles. A PDF can accompany it to define tolerances, threads, surface finish, and other requirements. The PDF is not a substitute for the model in instant quoting.
Laser cutting needs planar geometry
DXF carries the 2D cut profile. Export at full scale and verify inches or millimeters. A drawing sheet with dimensions and borders is different from a clean manufacturing profile. An image embedded in a DXF is not automatically usable vector cut geometry.
Printing supports solids and meshes
The printing quote accepts STEP/STP, STL, and 3MF. STL typically carries no reliable unit definition, so dimensions must be checked. A printable mesh needs closed, consistently oriented surfaces. A 3MF file may include extra project information that does not substitute for an agreed manufacturing requirement.
Native CAD and archives
Fusion and SolidWorks native files should be exported to an accepted format before using the upload tools. Renaming an extension does not convert geometry. The custom RFQ accepts optional PDF and STEP/STP files; ZIP archives and unrelated file types are not part of that upload route.
