In these professional drawing software, there are not only many kinds of exquisite product appearance drawings, but also smooth curves, inclined text labels and various special arrow and line drawing tools. As shown in figure 1- 19, Visio? An interface in 2003, in the center of the figure, is some network device primitives (from left to right: hubs, routers, servers, firewalls, wireless access points, modems, hosts) pulled by the author from the left primitive panel, from which we can see that the appearance of these device primitives is very beautiful. Of course, in practice, there are far more primitives that can be directly extracted from software. All these can be obtained directly from the graphic panel on the left. This section and the next section will briefly introduce the application methods of these two kinds of network structure software in network topology drawing.
Visio series software is an advanced drawing software developed by Microsoft, belonging to the Office series, which can draw flow charts, network topology charts, organization charts, mechanical engineering charts, flow charts and so on. It is powerful and easy to use, just like Word. It can help network engineers to create business and technical graphics, organize and record complex concepts, processes and systems. Visio？ 2003? It can also provide the latest graphics by directly synchronizing with data resources, and can also be customized according to specific needs. The following are the basic steps to draw a network topology.
(1) Run Visio? 2003 software, select the "network" option in the "category" list on the left side of the opened window as shown in figure 1- 12, and then select the corresponding option in the right window, or in Visio? In 2003, when you perform a menu operation under the menu of New → Network, you can open the interface as shown in figure 1- 13 (here, take the option of "Detailed Network Diagram" as an example).
