M. Application Window Layout
The main Section Builder window displays the current composite section. All of the primary commands are activated through the menus along the top of the window. There is also a status bar along the bottom of the window which displays the overall dimensions of the composite section and the location of the cursor when it lies over the main workspace. Additionally a dimension value will be displayed in the status bar by clicking and dragging the mouse across the window.
Sections created in the Section Dialog box can be located onto a composite section relative to the nodes of the 'current section.' A section is made into the current section simply by clicking on it so that it is shown in yellow. Note how the nodes of the current section are identified as potential locating points for the addition of new sections.
