This task shows you how to save
in IGES format the data contained in a CATPart, CATProduct or a
CATShape document. However, if you re-import an IGES file made from a CATShape, you will create a CATPart. |
|||
The table entitled What about the Elements You Export ? provides information on the entities you can export. |
||||
You can find further information in the Advanced Tasks:
and in the Customizing 3D IGES Settings chapter. Statistics about each export operation can be found in the report file created. |
||||
|
||||
|
|
|||
Several 3D IGES export options can be customized: | ||||
|
After the exporting data to 3D IGES files, V5 generates:
These files are created in a location referenced by

The list below shows the IGES element numbers corresponding to the element types in Part Design. |
V5 Element |
IGES Element |
|||
null | 0 | |||
circle | circular arc | 100 | However, in B-Spline mode (see options), all planes and surfaces are exported to rational B-Spline surfaces (128) and all curves, circles and lines are exported to B-Spline curves (126) | |
curve, line, circle | composite curve | 102 | ||
curve | conic arc - ellipse | 104 form 1 | However, in B-Spline mode (see options), all planes and surfaces are exported to rational B-Spline surfaces (128) and all curves, circles and lines are exported to B-Spline curves (126) | |
point, curve | copious data | 106 form 2 | ||
plane | unbounded plane | 108 form 0 | Construction unbounded planes (supporting faces) are
exported as type 108, forme 0. Independant unbounded planes are not exported. However, in B-Spline mode (see options), planes and surfaces are exported to rational B-Spline surfaces (128) and all curves, circles and lines are exported to B-Spline curves (126) |
|
line | line | 110 form 0 | ||
Semi-bounded lines | line | 110 form 1 | ||
Unbounded lines | line | 110 form 2 | ||
point | point | 116 |
A point belonging to a sketch is exported only if the sketch contains only points. |
|
surface | ruled surface | 118 | However, in B-Spline mode (see options), all planes and surfaces are exported to rational B-Spline surfaces (128) and all curves, circles and lines are exported to B-Spline curves (126) | |
surface | surface of revolution | 120 | ||
surface | tabulated cylinder | 122 | ||
matrix | transformation matrix | 124 | ||
curve | rational B-spline curve | 126 | ||
surface | rational B-spline surface | 128 | ||
surface boundary | curve on parametric surface | 142 | In standard export mode:
If the surface support is of B-Spline type and C2 continuous, both representation of boundaries are defined (2D parametric and 3D model space). Otherwise, only the 3D representation is defined. In B-Spline mode all surfaces are exported as B-Spline surfaces (with 2D and 3D boundary representations). Those boundaries are ordered and oriented. |
|
surface | trimmed (parametric) surface | 144 | ||
Solid
|
Manifold Solid B-Rep Object Entity | 186 form 0 | To export those entities, the
Representation mode: Solid - Shell option must be active.
It requires IGES 5.3 or higher. All those new IGES entities have not been "tested" (IGES Norm 5.3) and the IGES/PDES Organization recommends that special consideration be given when implementing certain untested entities. Therefore if you do not know whether the receiver system will recognize those entities, we recommend that you do not use this option. For Loops, only the 3D Representation is exported |

Plane Surface (support of Face) | Plane Surface Entity | 190 form 0 | ||
Solid (Closed) Shell
|
Closed Shell Entity | 514 form 1 | ||
Independent Shell
|
Open Shell Entity | 514, Form 2 | ||
Face in a Shell

Face Entity | 510 form 1 | ||
Face Loop

Loop Entity | 508 form 1 | ||
List of Loop Edges | Edge Entity | 504 form 1 | ||
List of Start/End Loop Edges Vertices | Vertex Entity | 502 form 1 | ||
