Why won’t my STEP or STP file upload?

Having trouble uploading a STEP or STP format file to SendCutSend’s website? There are a few reasons why that might be happening! You’ll want to ensure that your design meets our 3D file guidelines.

For a STEP or STP file upload to be successful, it must meet these criteria:

Single, Solid Sheet Metal Body (No Assemblies or Mesh Bodies)

  • we need your STEP/STP file to contain a single, solid sheet metal body
    • we cannot accept files with multiple bodies stitched together / assemblies
    • we cannot accept files including mesh bodies

Part Aligned Flat To Drawing Plane

  • we need the part in your STEP/STP file to be aligned flat to at least one drawing plane
    • we cannot accept files with parts that are not aligned flat to any plane

Part Without Dimensional Features

Sheet Metal Body Using Correct Material Thickness

  • the part in your STEP/STP file must be a “sheet metal” body – not an extruded flat pattern
    • please set up your design with a thickness offered in SendCutSend’s material catalog
    • parts designed with a thickness greater than 0.500″ may not upload successfully

Sheet Metal Body Using SendCutSend Specifications for Bending

Avoid Complex Designs with Many Cutouts and Detail

  • designs with many features should be exported to DXF
    • these designs result in large file sizes in the STEP format
    • if your part will be detailed, export your design to DXF for successful processing

Revise your file to meet our 3D file requirements and design guidelines, then try uploading again.

If your file still does not upload successfully, please contact our Support team. Let them know which program you’re using to design your part and attach your file so they can take a look!

In Summary:

Why won’t my STEP or STP file upload?

Your file may not upload to SendCutSend’s website successfully if
– it includes an assembly
– the file exported incorrectly and/or is invalid
– it is not aligned flat to any drawing plane
– includes a mesh body
– has dimensional features (chamfers, countersinks, filets, tapered edges, etc.)
– is not a sheet metal body
– does not have a uniform thickness
– is set up with a thickness greater than 0.500″
– will require bending services and is not using SendCutSend’s bending specifications
– includes highly detailed cut geometry
