Buyer Guide

DXF, STEP and PDF File Guide

DXF, STEP and PDF files each answer a different manufacturing question. Sending the right combination helps the supplier quote sheet metal parts with fewer assumptions.

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.

InputWhy it matters
DXF or DWGBest for flat profiles, laser paths, holes and slots.
STEP or STPBest for formed context, assemblies and enclosure fit.
PDF drawingBest for tolerances, notes, finish and inspection requirements.
ZIP packageUseful when multiple parts, BOM files or marked screenshots belong together.
Sample photosHelpful 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.
