A geometric tool for capturing the relative positions of points on a geometric profile, thus creating a template for use in geometric representation and replication. The geometric tool comprises three or more pointers, and a means for constraining motion of the pointers. The pointers each comprise a rigid longitudinal member with a definitive a tip. The means for constraining motion of the pointers is such that the pointers can only pivot and radially translate with respect to a shared axis of rotation. In addition, the means for constraining motion of the pointers also contains a mechanism for the user to fully constrain the pointers with respect to the shared axis of rotation. This construction provides a simple and convenient geometric tool which offers an errorless method for capturing the relative positions of points on a geometric profile for use in further representation and replication.
