Do the Extend Line and Trim Line tools create an output feature class, leaving original features unchanged?

The Extend Line and Trim Line tools are designed to modify the existing line features in a geographic information system (GIS). When you use these tools, they directly alter the geometry of the original line features rather than creating a new output feature class. This means that the original features are not left unchanged as they are adjusted to extend or trim based on the tools' operations.

By understanding the function of these tools, it becomes apparent that they are intended for direct manipulation of line geometries, making the assertion that they create a separate output feature class while leaving originals intact inaccurate. In contrast, there are other tools in GIS that may create a copy or new feature class while keeping the original data unchanged, but the Extend Line and Trim Line functions do not fall into that category.
