Electronic IC_Chip Drawing System

"Electronic 1C Chip drawing system" provides many functions such as "modify the position of the component's diagram" "modify the color of the component's diagram" "magnify and minify the component's diagram without distortion" "change the type of drawing line" "edit some physical properties of the component" "copy and paste diagram of one component" "delete one or more component diagrams" "move more than one components' positions" "change the z_order of the diagram,set it to back or bring it to front""save the drawing of the electronic components to one file and the file extension name is *.brd" "print the drawing". Users can finish all these functions easily by clicking and dragging the mouse.In the electronic component drawing system, I use "vectorgraph" to magnify and minify the diagram without any distortion.The system provides many operating ways including "main menu" "toolbar" "popup menu". Especially, the shape of the cursor can be changed to the electronic component's shape as soon as you select one component.I adopted the "OOA" "OOD" "OOP" techniques to analyze and design and program the drawing system. At last, 11 classes were extracted. The UML and Rational Corp. Rose were used to design the "class diagram" "sequence diagram" "collaboration diagram".During the development of the electronic drawing system, I employed Microsoft Corp. Visual Source Safe to manage source code ,whitch isis an advanced source code control toot.
