DXF is useful for flat profiles
A clean DXF can speed up laser cutting review when the flat pattern is final. It should avoid duplicate lines, open contours, mixed units and unmanaged revision names.
STEP shows formed and assembly context
A STEP or STP model helps the reviewer understand bends, mating parts, hardware positions and enclosure closure. It is especially useful when the part is more than a flat plate.
PDF carries manufacturing intent
The PDF drawing should state tolerances, material, thickness, surface finish, thread callouts, PEM hardware, bend direction and quality requirements.
| Input | Why it matters |
|---|---|
| DXF or DWG | Best for flat profiles, laser paths, holes and slots. |
| STEP or STP | Best for formed context, assemblies and enclosure fit. |
| PDF drawing | Best for tolerances, notes, finish and inspection requirements. |
| ZIP package | Useful when multiple parts, BOM files or marked screenshots belong together. |
| Sample photos | Helpful for supplier rescue or replacement parts, but not enough for final quote alone. |
Next step
Use the guide to prepare a cleaner inquiry, then attach the best available files through the RFQ form. If an item is unknown, say so directly so the first reply can separate quote assumptions from confirmed requirements.
