Hello all,
I developed this system (and continues to be a work in progress) in order to standardize the models within our studio. It had been very confusing and slow to pass models around between staff and each model having its own personal layering system which had to be figured out. Its important to keep the layer box "name" carrot active to keep the layers in this order. The system allows the user to pull off floor levels from the top down and buildings are developed with a "pancake" method. This is the basic framework and model-specific layers can be added as needed:
.0 site plan (we use this as a CAD import or sketch overlay layer)
.1 site model (flat or sandbox grade)
.2 site construction (existing buildings, walls, etc)
.4 site entourage (people, etc)
.4.1 site trees (high poly trees on their own layer so they can be turned off)
.4.2 site cars
.4.X (additional points can be added as necessary)
0.0 basement plan (we use this as a CAD import or sketch overlay layer)
0.1 basement plate (the floor plate)
0.2 basement mass (walls, partitions, windows, doors)
0.4 basement entourage
0.4.1 basement furniture
1.0 first fl plan
1.1 first fl plate
1.2 first fl mass
1.4 first fl entourage
1.4.1 first fl furniture
2.0 second fl plan
2.1 second fl plate (or for single story buildings this could be the roof)
etc, etc
9.0 notes
9.1 dimensions
We also use prefix modifiers before the layer number to group certain items.
E Existing
D Demolition
for example: D1.2 first fl mass demolition
I think this operates similar to the system described in your post. Its interesting to compare how other models are organized. Thanks for the post!
