CATIA V5 format (Windows only)

The following entities are translated into CATIA V5 format.

Alias entity	saved to CATIA V5 format as
Curve (created with either CVs or Edit Points)	NURBSCurve of appropriate degree
Line	Line
Arc	NURBSCurve
Circular	NURBSCurve. Note that periodic objects will be divided into two.
Blend curves	NURBSCurve of appropriate degree.
Multiknot curve	NURBSCurve
Curve on surface	NURBSCurves
Surface	NURBSSurface.
Surface Revolve	NURBSSurface. Periodic objects will be divided into two.
Multiknot Surface	Surfaces divided in multiple surfaces if -d option is used.
Shell	Solid. Caution: Alias closed shell becomes a CATIA Solid. If -s option is specified, the shell’s faces will become surfaces.
sphere, cone, cube, and so on.	NURBSSurface. Periodic objects are divided into two.
Rational sphere, cone, and so on.	NURBSSurface. Periodic objects are divided into two.
Planar face	NonRationalNURBSSurface of degree 1 with a single span in U and V directions. Faces with holes will be transferred.
Shell	CATIA solid body, if shell is closed, or skin (open shell) if shell is open.
Surface with multiple disjoint trimmed regions	Multiple trimmed surfaces
Closed periodic curve	Periodic curves are divided into two curves.
Shader Color RGB	Color RGB
Layer	Layer (numbered). Layer name is ignored.
Invisible	Invisible (no show)
Construction vector	Line
Construction plane	Plane
Symmetry	Converted if -b option for layer symmetry is ON.
Space point, Curve point, Surface point, Curve-on-surface point	Point

The standard document types provided by Dassault Systemes are:

Part Document
Product Document
Drawing Document
Material Document
Catalog Document
Analysis Document
Process Document

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:

Mechanical Design: Part Design, Sketcher, Sheet Metal Design, Wireframe & Surface Design, Functional Dimensioning & Tolerancing.
Shape: Free Style, GSM Debug, Digitized Shape Editor, Generative Shape Design.
Equipment & Systems: Circuit Board Design.

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:

Infrastructure: Product Structure, Knowledge Advisor, Knowledge Expert, Generative Knowledge, Product Engineering Optimizer, Rendering.
Mechanical Design: Assembly Design, Structure Design.
AEC Plant: Plant Layout.
Digital Mockup: Navigator, Space Analysis, Kinematics, Fitting, Plant & Ship Review, Optimizer, Tolerancing Review.
Equipment & Systems: Systems Space Reservation, Systems Routing, Electrical Wire Routing.
DELMIA Infrastructure: Digital Manufacturing ReView.
