|---|---|
| Curve (created with either CVs or Edit Points) | NURBSCurve of appropriate degree |
| Line | Line |

| Blend curves | NURBSCurve of appropriate degree. |
| Multiknot curve | NURBSCurve |
| Curve on surface | NURBSCurves |
| Surface | NURBSSurface. |

The standard document types provided by Dassault Systems are:
A Part Document has a .CATPart suffix, and is mainly used during the design process. The Part Document is used as the default document type for the following workbenches:
A Product Document has a .CATProduct suffix, and is mainly used to assemble Product or Part documents in a structured, coherent system of sub-products and/or parts. The Product Document is used as the default document type for the following workbenches:
