3. I Intend to show… • How to easily predict the visibility of items, depending on the layer status. (Isolate, Hidden, Unhidden) • How to make effective use of putting items onto multiple layers. • And, I’ll demonstrate some cool mapkeys, that are based the info presented. They allow the quick and easy clean up of the layers of an entire assembly and it’s components.

4. So What Does Mastering Layers Involve? • Understanding exactly what has been put onto the layers. • Knowing “Invisibility Rule #1”. • Knowing how layer status impacts visibility. • The effective use of placing items onto multiple layers. • This makes it easier to choose what you want to see, instead of everything you don’t.

5. All Features Have Entities… • Datum Features - Axis, Csys, Curves, Planes, Quilts, Tag Names… FEATURES Plane Sketch Copy Geom DTM1 P3 P2 P1 GEOMETRIC ENTITIES

6. Coarse Level of Control Fine Invisibility Rule #1 • Once an item is rendered invisible; every sub item, in that branch of the model, is rendered invisible. • Assembly • Part • Feature • Entity * This is a fundamental in Pro/Engineer.

Layer Status Diagram (Assemblies) • Every aspect of layers in an assembly is the same as in parts, until a component is added to a layer – then things change, boy do they!

14. Layer Status (Assemblies) About putting components on layers… My Advice: Don’t do it! Simplified Reps are better for managing component visibilities

15. Putting It Together • Use Isolate in place of Unhidden. • Putting items on multiple layers becomes useful. • Creating new layers need not disturb existing layers. • Choose what you want to see, instead of everything you don’t. • Create, all inclusive, default layers only for the items found in the majority of your models. Don’t remove items from them, with Isolate, it isn’t necessary. • Create layers that suit your needs. • Save all layers with the status Hidden. Make exceptions only for things that need to be seen in ALL upper assemblies.

16. Demo: Config.pro, Drawing.dtl & Mapkeys • Config.pro • no def_layer options • add_lower_level_comps_to_layer no • Make the environment display options on by default. • Drawing.dtl • ignore_model_layer_status yes • draw_layer_overrides_model yes

17. Demo’s • Cleaning an Assembly • Using find to create layers. • Using the extend function to create layers, with rules, recursively. • Searching for items in the layer tree. • Using the selector to manipulate the layer tree. • How to distinguish between entities and features. • The quick cleanup demo. • Drawings & Parts • Create drawing layers, use them to keep changes to the model from impacting the drawing. • Skeletons • Layers to fit special requirements.
