In microsoft word:
"View" > "Toolbars" > "Drawing".
A toolbar will appear with basic and more complex shapes for use. Use a textbox to create a rectagle, and instert the text. Then use the line tool to connect individual rectangles.
Your other option is searching for free "Flow Chart" software in google. I have seen it before, so you shouldn't have too much of a difficulty, if for some reason you do like using the msword tools.
i am trying to create a diagram using a series of text labeled rectangles. the text is to be located inside the rectangle. each rectangle is connected to another rectangle by a straight line. any assistance on how to do this will be appreciated. thank you all.
