Modifying Multiple Layers Simultaneously Help Index layers modifying multiple Although you need to specify most properties for each layer individually, you can change the visibility status and the Autodesk MapGuide Server MapAgent URL of multiple layers at the same time. If you have several layers in a map, this can save you time. To modify properties of multiple layers, you use the Multiple Map Layer Properties dialog box, which you access by selecting two or more layers in the Design tab of the Map Explorer, and then choosing Properties from the popup menu.  For step-by-step instructions, choose Help Contents, click the Index tab, and look up "layers, modifying multiple." Saving a Layer After you save a layer as a Map Layer File (MLF), you can use it to create new layers in the same map or in different maps. This can save you time if you create similar layers repeatedly, because you can simply add the MLF as a new layer and make modifications to its existing settings. Therefore, you should consider saving commonly used layers as MLFs. Note that if the layer is static, the MLF will include all of the data for that layer, as well its properties. For more information, see the next section, "Adding a Saved Layer to the Current Map." You can also add MLFs to a map using the Autodesk MapGuide Viewer API. For more information, refer to the Autodesk MapGuide Viewer API Help. 174 | Chapter 9 Working with Map Layers
