The Bill of Materials, the 3D view and STEP export, and Output & Export.

In this section

Finish the BOM, check the board in 3D, and generate the fabrication and assembly package.

Review the project BOM

Check quantities, part numbers, and fitted state in the Bill of Materials, then export it in the format your assembler wants.

Export formats

Files Resin can export.

Manufacturing outputs come from Project > Output & Export. STEP, GLB, and IDF come from the 3D view's Export menu. KiCad schematic files and Altium files come from the schematic and PCB editors' Export menus.

KiCad project: .kicad_sch, .kicad_pcb, .kicad_sym, .kicad_mod; The full project, any time. Opens in KiCad 9.
Altium Designer: .SchDoc, .PcbDoc; Schematic and board written as native Altium files.
Gerber and drill: RS-274X, Excellon; One file per layer, plus drill files and a drill report.
ODB++: Zipped ODB++ job
IPC-2581: .xml
STEP: .step; Board and component models for MCAD.
IDF: .emn, .emp; Board outline and component placement for MCAD.
DXF: .dxf; Board outline.
BOM: .csv, .xlsx; Grouped by part, with the assembly variant applied.
Pick-and-place: .csv
Specctra: .dsn, .ses; For external autorouters. Importing a session merges wires and vias back into the board.

Set units, layers, origin, and the assembly variant before exporting, then open the files in the receiving tool and compare them with the board.
