Layers partition a project into one or more overlays. Layers are like transparencies in that you can see all layers at the same time, but they let you isolate objects by placing them on separate layers. Layers are created and manipulated using Layer Manager.
You can accomplish several things when you use layers in Didger. There are a few tips and tricks we can share that might help you use layers.
Use "NONE" for the fill pattern on polygons in top layers. Otherwise, objects on lower layers can be obscured.
Use layer names to easily keep track of what you have included on each layer.
Use layers to isolate different types of objects. It is easier to select and modify objects when you do not have too many objects on a single layer.
Make a layer uneditable when you are not working with it to avoid accidentally selecting, moving, or editing objects.
Show various approaches to your project by creating several layers and making some visible and invisible.
This project is divided into three layers, Base Map, Reference Lines, and Contours.
The layers can be made invisible or uneditable to aid in the editing process.
