The Define Plane dialog allows the user to create a plane of any orientation and location for the Locked Plane digitizing mode, the Align Plane digitizing mode, and the Project To Plane filter.
Plane Definition
A plane is defined by the vector normal to the plane, and the distance from the plane to the origin. The dialog has three fields for the I, J, and K components of the plane’s normal vector, and a field for the distance between the plane and the world origin of the FaroArm. Any numbers are valid for the normal vector of the plane except for zeroes in all three vector component fields. The Normalize vector button will calculate the normalized components for the vector entered in the component fields.
Digitizing a Plane
This dialog box allows a plane to be defined in space by digitizing three points within the plane. Press the Start button to begin the digitizing process. After digitizing each point, the user has the option to UNDO the last point digitized point. After the third point is digitized, the resulting plane is calculated using the position and order (for the normal vector direction) of the three points at that point in space. The position of the plane in space is determined by the shortest distance of the plane from the origin. After defining the plane, this offset is calculated and stored in the Distance from origin field of the dialog, and can be modified without altering the orientation of the defined plane.
