Abstract: A tool for tracing a curve from a first plane (such as a wall) onto a second plane perpendicular to the first plane (such as a floor tile) is disclosed. The tool includes a base member having opposite first and second ends with first and second sliders positioned on the base member adjacent the first and second ends, respectively. The sliders are configured to bear against the first plane simultaneously. The tool also includes an arm extending away from the base member with a marking tool positioned at an end of the arm opposite the base member. The marking tool is configured to mark the second plane while the first and second sliders bear against the first plane. The base member is preferably articulated and each of the sliders preferably consist of pairs of coaxially aligned wheels.
