Menglong project management system is a software specially developed by Guanglianda Company to draw network diagrams. The menu bar and toolbar conform to most operating habits. Each menu in the menu bar contains many options, and all the settings and operation entries can be found here. The toolbar lists the commonly used commands separately. In fact, the corresponding options can also be found in the menu bar.
Pay attention to the drawing status bar. When drawing a network diagram, the mouse can't directly perform the corresponding operation, but first click the corresponding status button in the status bar on the left, and then you can operate the content.
