The Copy command replaces the current contents of the paste buffer with all selected entities. Copied entities will remain in the paste buffer until
modified. To clear the contents of the paste buffer, use the Clear Paste Buffer command or the Copy
command with zero selected entities.
Child entities are not copied to the paste buffer. As an example, if a database curve used to trim a surface were copied, the surface that it trimmed would
not be copied as well.
Tip: You can copy text to or from any of the Pointwise text fields making it convenient to copy in strings representing coordinates or
possibly entity names from other software packages.
