DIA: Using Diagram Designer Rapid drawing flowchart, UML and other graphics __uml_ Requirements _ design _ mode

Currently the more popular UML modeling tools include Visio, Rational Rose, PowerDesigner, EA, and so on, basically enterprise-class software, powerful, I have only used Visio, so do not add to their characteristics or similarities and differences. For more formal scenarios, such as graphics as part of a project document, the software listed above is recommended. When we encounter more complex code logic or business logic at work, it is easier to understand them in graphical form, and in this case, a simple and lightweight modeling tool can be used to quickly draw. Here to recommend a good small software: Diagram Designer, installation package about 1.3M, the following figure is its main interface:

You can use it to draw a variety of graphics, such as UML, flowchart, interface construction, etc., for commonly used graphics Diagram designer provide the appropriate template, so, through the template can support more kinds of graphics, custom graphics elements used to be handy, I think a lot of the graphic elements in Visio don't work. The left half is the drawing area, and the right half is a template that contains various graphic elements, dragging the elements of the template directly to the drawing area. If you want to use a different template, you can choose to load the template, or we can modify the existing template to remove unwanted or added new content. The drawing area defaults to no grid, and it is recommended that you make the grid visible when you use it, which makes it easier to place and align elements. It is convenient to copy the elements that are already in the drawing area in Diagram Designer, just hold down the CTRL key and then use the left mouse button to select the elements you want to copy, and hold down the left mouse button to copy the same new element, which can greatly speed up the drawing. If you want to modify the various information of an element, just click the mouse to modify the element, Diagram Designer will pop up an edit dialog box, we can only change in the form of formatted code, as shown in the following figure:.

Diagram Designer supports creating multiple pages, you can quickly switch to the specified page by using CTRL + page numbers, or you can name and reorder the pages. For multiple pages of graphics, you can use slides to browse, this function is very practical. Select multiple elements to hold down the SHIFT key instead of the CTRL key.
