||This task shows you how to visualize a V4 Support Edge that was not
transferred in V5 geometry during the conversion of CATIA Version 4
models into CATIA Version 5.
V4 Data conversion through Copy / Paste is
useful but contains a few restrictions, only V4 geometry is migrated and
cannot be edited. In the following example, the Copy As Special process is
used; therefore the Specifications are generated in V5.
Create a new document in CATIA V5, a new part, Part1.
Both documents can be open in the same CATIA window:
Copy / Paste As Special the .model in Part1. A
Paste Special dialog box appears, select CATIA_SPEC and click
At this step, only specifications or definitions have
been built; they are visible in the Specification Tree of Part1. Here is
a part of the Specification Tree:
Update the document, Part1, so that the geometry
calculation operates. When the update is finished, an Update Diagnosis
dialog box is displayed:
The error is in definition of the Edge.Fillet.6
corresponding to the V4 Fillet ($FILL14) and it cannot be placed into the
Press the button Edit in order to modify the Fillet and
the error is explained in a new dialog box entitled Feature
Definition Error. Click on OK to delete the Edge.
Select the object (highlighted with yellow dots) to be
filleted in the Edge Fillet Definition dialog box. The radius (R3 in
green) and Propagation correspond to the V4 data that have been kept
during the transfer.
Before you select the Edge:
After the selection:
Click on OK: the calculation of the fillet geometry is
launched. The result in V5 is:
Both objects in V4 and V5 are similar and you
can now modify the V5 CATPart in CATIA Version 5. At the same time there
is an additional element, Pad.3 ($CYLN18) present in the geometry space.
In this transfer, the V4 geometric curve is
migrated into V5 and it is visualized in yellow. This is what we call the
reroute mechanism: a contextual primitive (a Fillet, a Chamfer, a
Support or a Feature Draft) is unsolved and the Modeler (in Part Design)
is able to visualize the former geometric shape and the Fillet's
Specifications when they are not solved in V5.
