When extruding a face, there should be an option to reference or snap to existing geometry (such as another solid face) to define the extrusion distance automatically instead of manually entering a value. This would allow the extrusion to dynamically match selected geometry and improve modeling efficiency by reducing repetitive dimension input.

For example, the user could simply tap a solid face, and the extrusion would automatically use that face as a reference and apply the correct distance based on it.
