❒. In the option window, choose CATIA
V5 from the list of file formats.
The following Alias entities are saved into CATIA V5:
| Alias entity | saved to CATIA V5 format as |
|---|---|
| Curve (created with either CVs or Edit Points) | NURBS Curve of appropriate degree |
| Line | Line |
| Arc | NURBSCurve |
| Circular | RationalNURBSCurve. Note that periodic objects will be divided into two. |
| Blend curves | NURBSCurve of appropriate degree. |
| Multiknot curve | NURBSCurve |
| Curve on surface | NURBSCurve |
| 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. |
| 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 |
