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 parts. All requirements will be derived from either the 3D CAD Model, the Job's PO, or the PDF Drawing itself unless otherwise specified in job notes:
A print is required for supporting information that a model cannot capture. Examples of this are GD&T callouts, tap sizes, inserts – Helicoil, pem, etc., surface roughness requirements better than a standard Ra 125 micro-inches, and both general (tolerance block) or specific tolerances i.e. reamed hole size, press-fit, etc. If there are any questions regarding when to apply the information, please contact us via the support request form.
