From the curiosity drawer. This python snippet uses “v1.5 command” functionality from back in the day to disable command logging for a specific command invocation.
from siutils import si # Application
from siutils import log # LogMessage
from siutils import disp # win32com.client.Dispatch
from siutils import C # win32com.client.constants
sClassID = "{19085F81-CDD6-471C-9CA1-7C7F4F2A0166}"
# This command is logged
si.FindObjects( "", sClassID )
log( "--------------------------" )
# Get the command and disable logging
oCmd = si.Commands("Find Objects")
oCmd.SetFlag( C.siNoLogging, True )
# Not allowed to update existing commands with Update()
# so we have to manually set arguments and execute the command
oCmd.Arguments(0).Value = ""
oCmd.Arguments(1).Value = sClassID
oICETrees = oCmd.Execute(); # Execute - nothing logged
for t in oICETrees:
log( t.FullName )
log( "--------------------------" )
# This still is logged, no need to reset flag because we never updated the command
si.FindObjects( "", sClassID )
The typical way to [temporarily] disable command logging is by setting the cmdlog preference:
Application.Preferences.SetPreferenceValue( "scripting.cmdlog", False )
Application.CreatePrim("Cone", "MeshSurface", "", "")
Softimage resets the pref automatically.
You could use a Python decorator to do this.

It being from the “curiosity drawer”, does this mean it doesn’t work anymore or could be done more easily. This post leaves some questions unanswered… 😉

Application.CreatePrim(“Cone”, “MeshSurface”, “”, “”)

Yes, but theoretically this still should work, or not?
Oh yes, it works. I tried it before I posted.
