Production choices

How EZCNC prepares your part

Upload a DXF and confirm the design units and finished dimensions. The quoting process can assign through cuts and supported drilling, pocketing or engraving operations to individual vectors. Unsupported or ambiguous requirements are sent to EZCNC for review before production.

Exact source geometry

Your uploaded source file remains unchanged. The preview and machining map are used to confirm the intended finished part.

Visible machining plan

Selected operations are colour-coded and listed so you can review how the vectors are intended to be machined.

Production confirmation

Material stock, dimensions and any manual-review requirements are confirmed before cutting begins.
