What term describes a situation where two components are touching but not interfering with each other?

The term that accurately describes a situation where two components are touching but not interfering with each other is "Coincident Faces." This terminology is used frequently in 3D modeling and design software, particularly in environments like Autodesk Inventor or AutoCAD, to indicate that two surfaces are exactly at the same location without any overlap that would lead to interference in assembly or operation.

When components have coincident faces, they share the same physical space in modeling terms but do not exert forces on each other, thus allowing for movement or other operations without hindrance. This concept is fundamental in maintaining clearances and ensuring proper function in mechanical assemblies.

In contrast, other terms like "Touching Faces" might suggest a mere contact without the precision that "coincident" provides. "Contact Surfaces" is less commonly used within this context and could imply a more intricate interaction rather than a straightforward adjacency. Lastly, "Adjacent Faces" implies proximity without guarantee of touching, making it unsuitable for the specified condition of contact without interference.
