2-Model Machining GCDs

The 2-Model Machining process group extracts two GCDs in addition to the other GCDs used in the Machining cost model:

  • source model

  • flat

For a detailed discussion of these GCDs, see the section "2-Model GCDs" in the aPriori Cost Model Guide.

GCDs

Source Model

you to visualize the difference between the initial raw part (the “source” model”) and the finished machined part by displaying a transparent representation of the source model while you are viewing the finished model.

 

Flat

Represents geometry that is typically (for example, to clean off a surface so that it mates better with another part or fastener). It typically is generated only for geometry that is milled and not turned, as Ring GCDs typically are generated for turned geometry
