About Worksheets
You may find that the “exploded” 2D elements generated from the model often contain superfluous elements (extra line segments, overlapping or superfluous fills) that make such editing difficult. To make editing easier, first use the Linework and Fill Consolidation functions on selected items in the window.
To open a Worksheet window, double-click its name in the Navigator. (You can also access Worksheets through the Go command of the Mini-Navigator Toolbar, or from the Window > Navigate > Worksheets menu, or from the Window menu.) Use the available 2D drawing tools, place objects, text, labels, or paste an existing drawing into the drawing window.
