To get started, select Automatic Sitemap in the Extensions category.
Selecting Sitemap Options
The extension works by interpreting the sitemap.xml used to index your site by Google. Point the extension at this file. If your file is named sitemap.xml and is stored at the root of your site, you can just point to the website, but if your xml file is stored in a different location or is named something other than sitemap.xml, it's safest to to specify the source of the xml sitemap with a url and then filter which parts of the site you want to include in your diagram.
You can also use the Browse button to upload a sitemap.xml file from your desktop.
Sitemaps with a lot of pages can be too cumbersome and difficult to comprehend, so try to limit the directories you include. SmartDraw has a 600 item limit on sitemaps, but you may want to limit your visual to even fewer components.
You can also choose whether to show the "leaves" of the tree in tables or as separate shapes. Each shape representing a page can be hyperlinked to its url.
Build your Sitemap
When you're ready, click "Build Diagram" to draw your sitemap automatically. Once you've opened your document you can edit your sitemap diagram like any other SmartDraw diagram.
