Options Dialog - Working Coordinate System Page

Used to set the origin of the working coordinate system that is used when creating curves.

To set the working coordinate system, choose the required option then click the Apply button.

To set the system in an orthogonal plane, select either Section, Waterline or Buttock and enter the required Position.

To set the system in the plane of a Diagonal or Cline, select the appropriate option and select the curve with the cursor when prompted.

Vertex & Vertex allows the User to select two vertices that define a line, the coordinate system will be normal to this plane with its origin at the first vertex.

The system can be set normal to the end of a curve or an edge, by selecting the Curve End Normal option, then when prompted, selecting the vertex to be used as the origin, followed by the edge or the curve that defines the normal.

The User can explicitly define the working coordinate system by giving the global coordinates of the origin and the vector defining the normal, using Position & Normal option.

The working coordinate system can be moved parallel to the existing plane by selecting Offset WCS and entering the required Distance.
