CATNOSTARTDOCUMENT=no
CNEXTSPLASHSCREEN=no
CNEXTBACKGROUND=no
А давным-давно по форумам ходил список переменных, которые вроде как улучшают жизнь

Напомню:
CATLM_ODTS=1 Disable license error messages at startup
CGM_ROLLINGOFFSET=1 Access to the Rolling Offset option in GSD
CNEXTOUTPUT = Console To dump the CATIA V5 Output to console
IRD_PART_COMPARISON = 1 bietet die Partdesign-Umgebung unter Tools die Funktion "Teilevergleich".
IRD_PRODUCTTOPART=1 It will enable a hidden fuction: CATProduct to CATPart...and, in "Assembly WorkBench" look under Tools menu
L_WILSON_LAN=1 Access to Wilson's spline curves
MFG_CATMFG_REMOVE_MOTION_TOOL_CHANGE = 1 remove th GOTO X Y Z during toolchange in APT file
MFG_MULTI_MP_APPLY = 1 multi instantation the manufacturing process
MM_NO_REPLACE = 1 Associativty about replacement of components cloned with different
PRINT_WITHOUT_DEPTH=1 remove the mask from the text on the print (only in V5R10)
SHOW_CST_CHILDREN = 1 Display stresses in the parents specification tree in sketcher
TAILLE_MEMOIRE_CHOISIE=1 Optimize IGES export memory
KEEP_HIDDEN_ELEMENT=1 No Show Elements are migrated
cleanV4Topology=1 It cleans topology automatically
CATMigrSolidMUV4AsPart=1 By Pasting "As_SPEC" It migrates SolidM into CATPart
REPORT_BREP_INFO=1 It makes migration report
V5V4SaveAsVolume=1 It migrates *SOL to *VOL
V5V4CleanTolerance=0.01 maximum gap used by automatic topology cleaner
V5V4MaxSimplif=1 It tries to concatenate small surfaces with large adjacent surfaces
SAVE_AS_ONE_PDF=1 damit wird beim "Speichern unter" einer mehrblдttrigen Zeichnung als pdf-Datei alle Blдtter in einem pdf File zusammengefasst (ansonsten gibt es pro Blatt ein pdf-File.
Так вот в чем вопросы: Rolling Offset и Wilson's spline curves - это что такое?
И еще. SAVE_AS_ONE_PDF=1 - насколько я понимаю, чертеж должен сохраняться в виде одного файла pdf?
