Some processes require particular details about the part to be able to manufacture it. This is usually to obtain specifications about surface finishing, threading instructions or standards, or any other detailed aspect of your design.

According to each process, you will need supporting files if any of the following apply to your part:

  • Sheet Metal:

    • Your design has punches, threads and/or countersink holes.

    • Some surfaces need a particular finish.

    • You defined certain tolerances.

  • 3D Printing:

    • There's no need for supporting files if the main file is correctly prepared for 3D Printing. Check this out to make sure you aren't missing any detail: How to prepare files for 3D Printing?

  • Injection Moulding:

    • A 2D drawing of your part, in addition to the 3D file, will be enough to quote for Injection Moulding.

    • A picture of the surface finish you would like is also helpful.
