While having the scanned drawing office.tif opened (see the previous section), click Switch to TCD Mode option from the Document menu to display the TCD Contents window presenting the structure of the composite document. Click the root TCD node using the right mouse button to show the Composite Document pop-up menu ( CDM ) and choose the CDM Add Subdocument option in the CDM pop-up menu that appears. Choose office.dwg vector drawing from the SuperEdit ’s DOC subdirectory.

SuperEdit should show a DWG with a complete drawing border, some walls, doors and other objects drawn over the scanned background. If you don’t see the entire drawing, as shown in the figure below, use the Zoom Extents button.

The new walls and doors are meant to replace the old ones that must be removed from the raster image. In order to see how this should look like when done, use the CDM Add Subdocument option as described before and choose office2.tif from the SuperEdit ’s DOC subdirectory. Right-click the office.tif node in the TCD Contents window and choose the CDM Remove option.

Whenever you need, e.g. for the reasons of the graphics screen clarity, to take some drawing temporarily off the screen, simply choose the CDM Disable option. The option changes to CDM Enable , so that you can bring the background image back, when you need it there.

The combination of office.dwg and office2.tif makes up a hybrid document that shows the intended modifications of the building floor. Both raster and vector components of the hybrid drawing may be printed together. The next section describes how to get the modified office2.tif .
