The Convert Copy to Lines command works like the Convert to Lines command except that it first makes a copy of the object and then converts the copy into line segments. The original object remains intact.
To convert a copy of an object to lines:
Select the object to convert.
Select Modify > Convert > Convert Copy to Lines.
If the object is 3D, select the wireframe, hidden line, or dashed hidden line rendering conversion option. The selected render mode determines which lines are visible, and therefore, created.
Click OK.
A copy of the object is converted into lines and each segment can be manipulated.
