# make_line_redge ## API Definition ```python def make_line_redge( start: Tuple[ScalarLike, ScalarLike, ScalarLike], end: Tuple[ScalarLike, ScalarLike, ScalarLike], *, tag_prefix: Optional[str] = None, ) -> Edge ``` *Source: operations.py* ## Import Surface - top-level: `from simplecadapi import make_line_redge` ## Description Create a straight edge between two points. When `tag_prefix` is provided, the edge receives the topology tag `.edge`. Downstream profile and feature operations may preserve that tag when kernel history proves the correspondence.
