3D models in ALICE are often rapid prototypes for visual planning and simulating of project constraints. A detailed (geometrically accurate) 3D model is NOT required for planning in ALICE.
- Most ALICE projects start with LOD 100 models and can continue to manage the project with LOD 100-300 models.
- ALICE Recipes enable customers to detail the assembly process within recipe operations and add CPM logic in the recipes
We like to remind customers that 3D elements in ALICE can represent a particular element (wall, slab, core), or they can be grouped together to represent a scope of work, level, or system.
Below are examples of varying 3D model LOD phases and how the models are dynamically developed at each phase in the project lifecycle:
LOD 100 Model with Level 2 to 4 schedule detail
This is a commercial Template model for with a telescoping schedule detail for bidding and precon Projects can start planning at a systems level in the conceptual phase and then expand detail in precon
