Advanced Layering Questions
I have been diving into layering quite a bit lately. I have established 9 layers that seem to catch most of my geometry, but I still have some questions. Are there any other layers people would recommend to me and can you answer a couple of my outstanding questions.
I have set this up as a universal layering system for assemblies and parts to allow use of the "extend layers" functionality and I have set up a mapkey to restructure any assemblies/subassemblies/parts to this layering system. All layers are rule based, associative and non-discrimanant between part/assembly
1 datum planes - catch all datums
2 gtol planes - designating a plane puts it on this layer and removes from layer 1
3 all axes - all axis
4 all curves - curves and sketches (Feature => curves)
5 all dtm pnts - points
6 all dtm csys - coordinate systems
7 all surfaces - Need help with a good rules, i was told (feature => surfaces ) and (features != > wall surfaces) or (feature => transformed surface)
8 all annotations - catch all GD&T
9 all cosmetic threads - cosmetic threads ( feature => has threads)
Basically does someone have a good surfacing set of rules? Also, how are people dealing with assemblies that have imported parts that come in completely as surfaces. Also, is there any other layers I should consider adding to catch all non-solid features.
My last question relates to the drawing. When i go into a drawing it has all of the layers above plus an extra layer. This extra rule based layer includes all of the drawing notes, added dimensions etc. When I edit the rules of this layer, it is simply an annotation layer but when I preview it there is nothing there. I cannot seem to find this layer defined in the config.pro, metric.dtl, drawing.fmt, etc. Does anyone know where this layer comes from, since it is specific to the drawing?
