A layer in Pro/E represents a model entities grouping (ex: features, datum planes or axes.) The layers are used to administer the entities in a model, assembly or drawing in Pro/E. Several entities can be associated to a layer, so as to manipulate them together. They can be suppressed if they are solids, and hide or be displayed in an organized fashion if they are non-solids.
The layers help to simplify a model and increase work speed.
The visibility of non-geometric entities can be controlled in a model or in assembly components with the help of layers. Also, unnecessary elements of a drawing (surfaces or datum features) can be hidden.
What kind of items can layers manage?
Layers can manage all types of items. After they were created, several items can be associated to layers, such as: features, curves, surfaces, datum planes, text, dimensions, geometric tolerances, etc. An entity can be placed in a layer in the following ways:
- Manually, by selecting the entities individually
- By copying layer information
- By creating layers and associating specific attributes automatically
