CADWorx Structure tab: Drawings panel > Modify > 2D Representation Hidden
You must create a drawing before you can access this option in the Modify palette.
Command line: 2DREPHSTR
Creates a 2D representation with hidden lines. This command exports the hidden lines from solids to the 2D representation. All other features of this command are similar to the 2DREP command. For more information, see 2D Representation.
When you XREF an item into a drawing, check that the Solid History of the object is set to None before running 2DREPHSTR.
