3 points: Specify 3 nodal coordinates to define the node's local coordinate system P0: Coordinates of the origin of the node's local coordinate system P1: Coordinates of an arbitrary node on the node's local x-axis P2: Coordinates of a node moved from P1, parallel to the node's local y-axis Vector: Specify 2 vectors to define the node's local coordinate system V1: x-direction vector starting from the origin of the node's local coordinate system V2: Vector starting from the origin of the node's local coordinate system to the point P2 of the 3 points method above Line Vector: Specify a reference line to define the node's local coordinate system. Direction: Select the component of node local axis. Selected component will be aligned into the orthogonal direction of the reference line. Ref. Point: Specify 2 nodes to define a reference line. P0: Coordinates of the origin of the reference line P1: 2nd point of the reference line to determine the direction of reference line. Global Direction: Specify a origin point and global axis to define a reference line. P0: Coordinates of the origin of the reference line P1: Component of the GCS axis to determine the direction of reference line. Note
