In Australian commercial construction projects, an inside corner is not explicitly defined in the provided contexts. However, based on the general definition of a corner window , we can infer that an inside corner refers to the point where two interior walls meet, forming an angle, typically 90 degrees.

In the context of building measurements, the inside face of exterior walls is used as a reference point for calculating enclosed spaces and usable areas . This suggests that inside corners are important in determining the overall layout and dimensions of a building.

It is worth noting that the Australian Building Codes Board (ABCB) provides guidelines and standards for building construction, including definitions and terminology. However, without a specific definition of "inside corner" in the provided contexts, we can only rely on general interpretations.

For precise definitions and guidelines, it is recommended to consult the relevant Australian building codes and standards, such as the Building Code of Australia (BCA) or the Australian Standard AS 1100 for technical drawing
