This task shows you how to import to a CATPart
or CATProduct document the data contained in a STEP AP203 / AP214 file. It is also possible to insert a STEP file as an existing component in a CATProduct. 


Regarding AP214, both STEP AP 214 IS and STEP AP 214 DIS files are read.  
The table entitled
What about the elements you import ? provides information on the entities you can import. You can find further information in the Advanced Tasks: and in the Customizing STEP Settings chapter. Statistics about each import operation can be found in the report file and the error file.


The File Selection dialog box is displayed.

The File Selection dialog box is displayed.


This displays all .stp or .step files contained in the selected directory : 







A progress bar is displayed.
You can use the Cancel button to interrupt the transfer at any time. 

What is then displayed depends on the contents of the STEP
file.
For the File/Open command:
The geometrical elements of the faces, which could not be transferred,


For the Insert/Existing component command:
The resulting document is inserted in the current CATProduct document,






Several STEP options can be customized:



After the recovery of STEP files, the system generates:
These files are created in a location referenced by the CATReport variable. Its default value is


Always check the
report and error files after a
conversion ! Some problems may have occurred without been visually highlighted. 

Example of a report file(Some lines have been replaced with ...) 



Legend 

OK = Transferred KO = Not Transferred NS = Unsupported 
OUT = Out Of Size DEG = Degenerated INV = Invalid 



Example of error file:
E:\Report\pm6hc214.err 

Report messages 

Here are some of the messages that may
appear:


When the Continuity optimization of
curves and surfaces/Advanced
optimization option in T ools/Options/Compatibility/STEP is active, the following warning messages may appear in the report file:

Exchanging 3D GeometryOne of the current primary uses of the AP214 Standard is to exchange
geometry.




Exchanging Visual Presentation of 3D GeometryAnother use of the AP214, or AP203 with
extensions Standards is to Please remember: 

As the unit system used in Version 5
is MKSA (radians, mm) data from all STEP files will 









AssembliesSTEP files containing assembly structures can be imported.
