Selecting a Drawing Method
If you are creating an entity relationship, class, or unstructured diagram, choose the method
by which to draw the diagram. Standard is the normal manual process where you control how
objects are added to the diagram. The view method automatically creates a diagram based on
the type of view selected. Refer to The View Functions later in this chapter for more
information.
Select the Drawing 3 Set the desired drawing method.
Method:
4 If you are creating a class diagram using one of the view
methods, and you want entities to be included as classes,
select Include Entities. Once an entity is added to a class
diagram, it is converted to a class in the repository, with
an entity subtype. It can be used freely on both entity
relationship diagrams and class diagrams.
Selecting a Page Size
When choosing the page settings for a diagram, either when creating a new diagram (New
Diagram from the File menu), or changing an existing one (Settings from the Diagram menu),
the following options are available.
Workspace
· Standard defines a single page drawing area. The dimensions of the page are determined
by the page size, scaling factor, and orientation. Prior to version 6.1, standard defined a
9 x 11 inch drawing area.
· Multi-page defines a 180 x 176 inch drawing area. On a multi-page diagram workspace
the places where the diagram breaks over pages when printed are indicated. These marks
are determined by the page size, scaling factor, and orientation, and do not print on your
diagram. While it is permissible to use this multi-page size for any diagram type, it may
not always be the wisest thing to do. Remember that one of the principles of analysis is to
break things up into small sections that take up no more than one standard page to make
the concepts more manageable and easier to understand.
Orientation
Portrait indicates the page is taller than it is wide; Landscape indicates the page is wider than
it is tall.
Page Size
Choose one of the available paper sizes for your printer. The size you choose affects the size
of the diagram workspace. If you have chosen the standard workspace, a diagram is printed on
a single piece of paper. If you chose multi-page, the number of printed pages depends on the
page size selected.
