In Object Manager tree, I need to inhibit multiply functionality, using CTRL+Drag&Drop.;
If I drag an object (Cube) below the tree, I obtain a new object (Cube.1)

I found to set "NBIT_NO_DD" bit before to add the object in tree.
"pMyObject->ChangeNBit( NBIT_NO_DD, NBITCONTROL_SET );"

It works (I can't multiply it) but D&D; functionality doesn't work any more. In SDK "NBIT_NO_DD" means "No drag and drop duplication."

Do you know other solution?

Is there any flag to stop CTRL+Drag&Drop; functionality?
Or a C4D message...

Any info is useful for me.
Thank you,

apparently the SDK Docs are wrong on NBIT_NO_DD. We'll fix this.
Unfortunately I don't see any way to only disable the Ctrl-Drag&Drop.
