The Benefits of Layers

Layer information can be given on all subpicture levels and on single geometry items. This is a great advantage when layers are used. Consider the following example: All measures are given the system layer -1 on the level 3 subpictures. Now, suppose there are three users from different departments that work on the same drawings. Each user has used a unique layer number or layer class where the layer for measures has been specified. The user will now have the possibility to handle (for example, skip or select) all measures, to handle only his own measures or to handle other users' measures. Conventions, for the use of layers, should be defined before the work is started.
