Layer Class

A layer class contains information about grouping of different types of items in a drawing in layers. The user can define as many classes as needed in an external file. A layer class can contain any of the layers for measures, notes, position numbers, hatch patterns, created 2D geometry, general texts and general symbols. It is possible to add a name to the layer class. If the system creates items of types not covered by the currently used layer class, their layers will be undefined. An example of a layer class file may be found in Appendix 12, Layer Class File.
