What kind of drawing do I need to quote?

The type of drawing depends on the type of process or part you are buying.

• We require 3D drawings for some parts to ensure accuracy and the best price possible.
• Generally, we support 3D and 2D DXF drawings for most parts.
• For customers purchasing hardware or custom fastener kits, no drawings are needed.

What kind of drawings do you accept?

Individual Parts

• All drawings need to be of a single, solid component.
• We don’t currently support quotation of multiple components.
• In case your drawing has multiple components, please save each part as their own drawing before uploading.

Supported Manufacturing Process

• Komacut currently offers laser cutting, bending, CNC turning and laser engraving for custom part manufacturing.
• Drawings which require stamping, punching, milling or other processes will be rejected by the platform.
• In case you have a part which requires a different production process, you can reach out to your account manager [hyperlink to service email] to discuss options.

3D Drawings

• What they are: a 3D model of the part that needs to be quoted and manufactured.
• What they’re needed for: We need 3D files to accurately nest, define bend angles and do all sorts of calculations for optimal part pricing and DFM analysis, and to manufacture certain types of parts.
  • CNC sheet metal bending
  • CNC turning
  • Chamfers
  • Milled features

• Requirements
  • Sheet metal drawing design must be made using 3D sheet metal modules.
  • 3D drawings must be of individual components, not assemblies
  • 3D drawings must be in supported formats
• Supported Formats: We support a variety of standard 3D software formats, including:
  • STP – File Extension: .stp
  • STEP – File extension: .step
  • Solidworks – File extension: .sldprt

2D Drawing Formats

• DXF Files
  • What they are: an editable, 2D representation of the part to be manufactured.
  • What they’re needed for: as a substitute for 3D drawings in cases where customers do not have, or to accompany 3D drawings of CNC machined parts.
    
    • Laser cut or CNC bending parts quoted without 3D
    • CNC turning parts – this is due to the tolerance and surface roughness requirements
  • Requirements
    • Must be a supported format (DXF)
    • Must be supported software version (see below)
    • DXFs should contain only flat pattern views. Any extra geometry, e.g. borders, another view, text converted to geometry extra will not work.
    • Parts without bends (i.e. laser cut parts) can be exported without layer mapping, on any layer, except layer '3'.
    • Drawings with bends will be rejected
  • Supported Formats:
    • DXF – file extension: .dxf

Guidelines for Sheet Metal Bending DXFs

Part with bends should be exported using the given DXF layer map.

Vector Files

• What they are: SVG vector images are composed of mathematical formulas that define the shapes in the image. This makes them scalable, so that they can be enlarged or reduced without losing quality.
• What they’re needed for:
  • These are used for logos, icons, so any parts which have laser engraving to them
• Requirements
  • Must be a supported format
• Supported Formats:
  • SVG – file extension: .svg
