CATIA TIP 1

CATCUST Values customization based on number of models involved in CATIA V4

In CATIA V4, there is a critical need for changing CATCUST values from time to time based on the following parameters.

1. Number of models to be opened
2. Model size
3. Complexity of models

However, user can choose to set the CATCUST values based on the number of models to be opened in CATIA V4.
Below table has values for major parameters like Active Index, Active data, Overlay index and Global extended data which can be set in the declaration file (Default : USRENV.dcls) through vi editor in UNIX.

Advantage:   Setting these values before opening the CATIA V4 models may avoid typical CATIA errors like,

1. Model full error
2. Insufficient model size problem
3. Impossible index reservation
4. Dynamic memory allocation problem
5. Section view update problem
6. CATIA V4 hang etc…

Catia Variables to improve the performance of CATIA V4 and “Auxview2 command in V4

Adding some variables in the “declaration’ (*.dcls) file will improve the performance of CATIA V4 and “Auxview2” command. Some of the variables are mentioned below.

CATIA.MODEL_MANAGE_OPTIMIZE : STRING ;
CATIA.MODEL_MANAGE_OPTIMIZE = ‘MEMORY’ ;

CATIA.SESSION_MANAGER_KBYTES = 5000 ;           (Value could be increased)

CATDRAW.AUXVIEW2.BIGACT : LOGICAL ;
CATDRAW.AUXVIEW2.BIGACT = FALSE ;
