NXOpen.Assemblies Namespace Reference (Python)
Verified identical to the C++ binding documented in full in
nxopen-cpp-reference/assemblies-namespace.md — read that file for the
complete class table, builder-family breakdown, and cross-reference to
NXOpen.Positioning.
Verification
87 classes (vs. 86 in C++ — negligible release drift), core types
confirmed present: Component, ComponentAssembly, and the surrounding
86-class object model (Arrangement, ComponentGroup, ComponentPattern,
AssemblyManager, ComponentOrder, and the full builder/search-term/
clearance/explosion family).
Python NXOpen code accesses these as NXOpen.Assemblies.Component,
NXOpen.Assemblies.ComponentAssembly, etc.
