The Drawing window is used to display raster and vector drawings that are opened by SuperEdit directly or as subdocuments of a TCD document. Individual images, subdocuments in the composite document, can be selected for changing their attributes, their position in the common world coordinates and their visible areas (viewports). One subdocument, a vector TVD drawing marked as a foreground drawing, is automatically selected for editing when SuperEdit opens a composite document that references it. You can graphically select entities of TVD foreground drawing for various editing actions. Raster editing actions are visualized by graphical interfaces that utilize vector entities.

For each subdocument, its visible area, called viewport, is defined. Initially (after adding a drawing to the composite document) it is set to full drawing extents. A viewport becomes visible as a thin black frame if the corresponding subdocument is selected in TCD Contents window. To enable editing viewports use Document – Select / Edit Viewport option or click the Select button on the Main toolbar. They change the state of Drawing window from normal to selecting and vice versa. A viewport can be resized by dragging small black rectangles, called trackers. They appear in the corners and in the middles of edges of the selected drawing’s viewport. The Reset Viewport command resets the viewports of currently selected documents to their initial sizes (full extents of each respective drawing). See Select / Edit Viewports paragraph for detailed description of states and actions.

You can save and display named views that you are working with. See Views Manager paragraph for details.
