Precautions to be taken in CATIA Version 4 Prior to the Copy Operation
This section describes the precautions to be taken in CATIA Version 4 Prior to the Copy Operation.
- If the model to be copied is an exact solid it must be processed using the Force Update option in the Smart Solid mode. This operation must be done on CATIA 418 or higher.
- It is also recommended to run the CATCLN utility on the model to be copied. Again, this operation must be done on CATIA 418 or higher. For more information see Using the CATIA V4 Cleaner.
- Remember to run the specification check on all the V4 models you
wish to copy to 3DEXPERIENCE as it provides you with the following
invaluable information:
- Identification of the primitives which are converted to datums, indicating loss of canonical information (see the Restrictions section below for the complete list). This is shown in the Message column of the Check Validity dialog box, for example: 2 primitives checked as geometry only.
- Identification of the operations which are not supported in 3DEXPERIENCE and must be deleted before proceeding with the copy operation (see the Restrictions section below for the complete list). This is shown in the Message column of the Check Validity dialog box, for example: 2 operations not implemented.
- Identification of the non-supported primitives (see the Restrictions section below for the complete list). For more detailed information, you only have to double-click on the appropriate message in the rightmost column of the Check Validity dialog box. This displays the contents of the model in the form of a specification tree (see Using the Interactive Checker).
- If, in 3DEXPERIENCE, you intend to make only cosmetic changes to a Version 4 solid with no impact on the specification tree you can simply copy the solid's geometry. However, if your modifications are major and will considerably alter the specification tree you would be better advised to copy the solid's specifications (see Copying 3D from CATIA V4 to 3DEXPERIENCE).
- Make sure that the update option selected in the General tab of the Options dialog box (displayed using the Tools > Options command) is not set to Automatic.
- When updating, make sure that you select the Inactivate option in the Update Diagnosis dialog box to deactivate any troublesome operations or primitives in CATIA Version 4. Do not delete them as such data, although not copied, can, once the rest of the model has been successfully copied, be recreated in 3DEXPERIENCE in a more satisfactory way. In a future version of 3DEXPERIENCE, this requirement will no longer apply.
