This task quickly shows you how to export the data contained in a CATDrawing document into a DXF file. | |||

The export unit
depends on the current unit of your session (see the Tools > Options > Parameters and Measures/Units panel).
So select the required type of session unit to export your data in one system or the other. |

Limitations in the case of a multi-sheet drawing:
|
|||
You can customize the DXF specific
export options:
|
||||
|
After the exporting data to DXF/DWG files, the system generates:
This file is created in a location referenced by

Both export options:

The table below sets the mapping between the CATDrawing file elements and the resulting DXF 2D elements.

Structures |

Sheet |
![]() |
One DXF file per sheet (see
option)
The graphical representation of each file is transferred to the space of the AutoCAD model |
||
Views | Interactive view![]() |
The structure is not exported.
|
The structure is not exported. | |
Generative view | The structure is not exported. All the geometric entities of the view
are gathered into a single Insert/Block. The above applies to CGR, approximate, exact views. |
|||
Detail (2D Component) |
![]() |
Details are retrieved through their Dittos. A Detail not referenced by a Ditto is thus lost, a Detail referenced by several Dittos is duplicated in BLOCKS. The entities included in a Detail are not structured into sub-blocks. | ||
Ditto (Instance of 2D component) |
![]() |
The graphical representation of each Ditto is exported to an INSERT/BLOCK | ||
