Xometry is a model-based company but there are times when a drawing may supersede what is derived from the CAD model. We put together a matrix to help you understand which file and which information we use as the source of truth to manufacture your parts. Unless you specify a requirement in the notes field of the Xometry Instant Quoting Engine℠ all requirements will be derived from either the CAD file, the drawing, or the quote itself.

Please note that while the matrix above generally describes what document we will follow to manufacture your parts, your order may be placed on hold so our engineers can contact you to work out any discrepancies that may affect the cost, lead-time, or manufacturability. To prevent such delays, the best practice is to carefully review your quote and ensure it matches your print requirements, and ensure you have uploaded the correct documents. In instances where a discrepancy is intentional, please make note of this in the part notes section while building your quote. Our engineers will update the instructions for our manufacturers once all discrepancies are cleared up.
A print is required for supporting information that a model cannot capture. Examples of this are GD&T callouts, tap sizes, inserts, surface roughness requirements better 125Ra µin, and both general (tolerance block) or specific tolerances. If there are any questions regarding when to apply the information, please contact us via the support request form.
