Remember that Autodesk MapGuide tips are here and use the right mouse button in MapGuide if you need help.
Zoom In - You need to zoom in to see the Section Grid data layer. The Section Grid layer is available at a scale of 1:100,000 or closer. If you zoom in far enough and turn on the "Parcels - Pima" layer, it is actually "on top" of Section Grid layer. In this case you need to turn off the Parcels layer to double-click on a section or to see Section Grid map tips.
Double Clicking - When you double-click on a section, you get a list of section-related links. Selecting "Corner Reference Sheets" shows you see a diagram of the section with links to the section corner reference sheets for that section. Since streets go through most areas, you may need to be careful to double-click on an an area in the section and not a street centerline or other map feature. You may want to zoom in more or turn off the Street Net to make it easier if you have trouble.
Two Browser Windows - Double-clicking on sections (and some other map features) in MapGuide brings up another browser window. You will then have one window for the request and one for documents. When you are in the document window, the browser's "Back" button does not take you back to the requesting window. After looking at documents, you can either use the "Done" button in the frame or dismiss the document window.
