Submission guidelines🔗︎

Dumaco stands for quality and processes orders quickly. However, it is important that the supplied files meet our specifications. If you take these guidelines into account during your design process, you prevent that the file cannot be imported or that you receive a product that deviates from your expectations.

Additional guidelines per type of processing

There are a number of standard guidelines that your file must meet. You can consider these general guideliness as the basis. Additional specifications may apply to the specific types of metal working which you are ordering.

No manual check

The file provided by you is the input for our manufacturing process, this is called "Design For Manufacturing (DFM)". You are responsible for this yourself. Drawing errors are not recognized and there is not a manual check after placing an order.

General guidelines🔗︎

  • Scale of the model is 1:1.
  • Unit is in millimeters (mm).
  • Dimensions are nominal.
  • Files must contain "solids" (no surfaces, triangulations or sketches).
  • Both a mono-part and composition are recognized.
  • Within a composition, amounts are also inherited.
  • Remove all parts from a composition that are not sheet metal.
  • The contours of blind holes, chamfers and roundings are engraved.
  • For a countersunk hole, the inside diameter is cut and the outside diameter is engraved.

!!! success “Smart use of file name” If the file name is set up properly, we can recognize the sheet thickness and numbers from it. These are then automatically set under the “material options”. This is ideal for calculations/orders where a large number of lines are uploaded at the same time. Read more on the file name.

Additional guidelines for metal working🔗︎

Additional guidelines and submission specifications apply depending on the type of metal working. For this, see:
* Guidelines for Laser Cutting

2D files🔗︎

We support 2D files in DXF (.dxf) and DWG (.dwg) format.

Guidelines:

  • Scale of the drawing is 1:1.
  • Unit is in millimeters (mm).
  • Dimensions are nominal.
  • Contours should be closed and should not overlap.
  • Do not use drawing frame, dimension lines, bending lines or center lines in the drawing.
  • Our software uses a smart way to recognize sheet metal:
    • The outer closed contour and all contours with the same color and/or layer are read in as cutting lines.
    • All contours with a different color and/or layer are read in as engraving.
    • If there are several parts in one file, our software will recognize this.
  • The view in the DXF is the top of the plate.

3D files🔗︎

We support 3D files in the following formats:

  • STEP (.stp, .step)
  • SolidWorks (.sldprt)
  • Solid Edge (.par)
  • CATIA (.CATPart)
  • INVENTOR (.ipt)
  • ACIS (.sat)
  • IGES (.igs, .iges)
  • JY (.jt)
  • MicroStation (.dgn)
  • NX (.prt)
  • Parasolid (.x_t)
  • PROe / Creo (.prt)
  • Revit (.rvt)
  • Rhino (.3dm)

Assemblies

For SolidWorks, for example, we unfortunately do not support assemblies (.sldasm) as they only contain a reference to other files on disk. In that case, export the composition as STEP.

Other files🔗︎

PDF or Graphic Design Software

Reading from a scanned drawing/document or a PDF file is not possible. We advise against using graphic design software such as Adobe Illustrator or InDesign to export or create 2D or 3D CAD files. These programs are not designed for technical precision and may result in file issues, such as inaccurate dimensions or incompatibility with our systems. To ensure the quality and reliability of your project, we recommend using specialized CAD software.

Material options recognition from file name🔗︎

If the file name is set up correctly, we can recognize the sheet thickness and quantities from it. These are then automatically set under the 'material options'. The separation between the different values in the file name can be done by a _ (dash), - (hyphen) = or space.

Thickness🔗︎

You can specify the sheet thickness in the file naming convention as follows:

  • 0-999 followed by mm. There may be a space in between, so either 1mm or 1 mm;
  • Both comma and period are allowed. For example, 2.5mm or 2.5mm;
  • Leading 0 is not allowed. So no 0.1 or 01 mm.

Number🔗︎

You can specify the number of parts in the file naming convention as follows: 0-99999 followed by one of the following words, with or without a space in between: x, stuk(s), piece(s), pcs, stück of stueck.
