Good morning Senthilvelrajan,
Sorry for delay, I've tried to find original videos. I've found them, but those are SWF files and content refers to version of Toad Data Modeler released before 12 years.
In modern Toad Data Modeler you have several options how to copy attributes:
- Copy attributes on workspace
- Copy Attributes in Entity Properties form (Attributes tab ... similar technique as above = Drag&Drop to Move or Drag&Drop with pressed CTRL to Copy)
- Copy Attributes in Model Explorer (via Clipboard)
- select attribute(s) in source entity
- press CTRL+C
- select destination entity
- press CTRL+V
