This task shows you
how to copy the specifications or geometry of a CATIA Version 4 model to
CATIA Version 5.
The following data can be copied from CATIA Version 4 to
CATIA Version 5: |
|
- surfaces (both polynomial and
BSpline)
- faces,
- volumes,
- skins and exact solids
- mockup solids (see remarks regarding
copy/pasting mockup solids
below),
- polyhedral surfaces and
solids,
- circles,
- ellipses,
- points,
- lines,
- planes,
|
- clouds of points,
- edges,
- parabolas,
- hyperbolas,
- curves (both polynomial and
BSpline),
- CCVs,
- NURBs (curves and
surfaces),
- PIP elements (Tubing),
- GPR elements (AEC Primitives),
- STR elements (planar structures, linear structures).
|
|
The
following task describes how an entire model is pasted from Version 4 to
Version 5. You can also select the geometric elements listed above and
insert them into an already existing Version 5 document. |
|
Open a .model. |
|
-
Open a new CATIA Version 5 CATPart document.
-
In the specification tree or geometry area where the
Version 4 model is displayed, select the geometrical element or elements
you wish to convert.
-
If you intend to copy the geometry you
can either:
- drag and drop the elements onto the appropriate location in
the CATIA Version 5 document
- or: click the Copy icon
, select the Edit>Copy command or
select the Copy
command in the contextual menu and click the
Paste icon
or select the Edit>Paste command
or select the Paste
command in the contextual menu.
-
If you intend to copy the specifications:
-
use the same methods as above,
-
in the Edit menu, select
the Paste Special... command or select the
Paste Special... contextual
command.
The Paste Special dialog box below appears:
- Select CATIA_SPEC and click OK. This operation
recovers the specifications previously put in the clipboard.
-
Click the Update icon
to view the copied data or use Edit > Update.
If you copied the geometry the
result should look something like this (using the Window > Tile
Horizontally command):
If you copied the specifications, the
result should look something like this (using the

Horizontally command):

Bear in mind the
following when copying / pasting:
- The migration of V4 model data to a V5
document generates a report (.rpt) file named after the model migrated:
- on Windows: in C:\Documents and Settings\user\Local
Settings\Application Data\DassaultSystemes\CATReport
- on UNIX: in /u/users/username/CATReport , but this depends on
the path setting in env file.
|
|
If you used the
CATIA_SPEC option mentioned above note that only the paste operation is
included in the report i.e. the actual update of the CATPart document is
not taken into account. |

Info Checker. |

When
copy/pasting mockup solids: If the solid has a history then the V5 specifications are
created. However, if the solid has no history or if the
CATIA_RESULT option is selected (using the
Paste Special...
command) then a cgr file is generated containing the visualization
information of the solid. The name of this file is "mymodel_SOLMxxx" and is
located in the same directory as the V4 CATIA model. This file can be
inserted into the Product Structure application. When copy/pasting
sets of surfaces : If you want to get a unique surface in V5, it is
more efficient to perform the join in V4 before the migration than in V5 on
the resulting surfaces. |

Detail used for Ditto |
In the interactive mode,
with the copy / paste AS RESULT of Dittos, the elements of the linked
Detail are copied AS RESULT, updated, and put into the No Show space.
In the Batch Mode, the elements of the linked Detail
are copied AS RESULT. |
In the
interactive mode, with the copy / paste AS SPEC of Dittos, the elements
of the linked Detail are copied AS SPEC, updated, and put in the No
Show space.
In the Batch Mode, you get a V5 Part or a Product. |
Ditto |
In the interactive mode, the
Dittos are represented in the Part by a link on the bodies managed by
the copy AS RESULT operation of the Detail elements.

In the interactive mode, the
Dittos are represented in the Part by a link on the bodies managed by
the Copy AS SPEC of the Detail elements.
In the Batch Mode, you get a V5 Part or a Product. |
Detail for
Macro-Primitives |
N/A |
In the interactive mode,
for the copy / paste AS SPEC of a solid using Macro-Primitives, the
elements of the linked Detail are copied AS SPEC, updated, and put in
the No Show space. |
Macro-Primitives |
In the interactive mode,
the solid who contains the Macro-Primitive is copied AS RESULT: it
means that only its BRep is copied, without specifications. |
In the interactive mode,
the Macro-Primitives are represented within the specifications tree of
the body by links with the copy AS SPEC of the Detail elements. |
