Add (3D) Offset

This facility allows the user to add an offset to the defined point, here called the basic point. The offset subcommand shall be selected prior to the basic point definition and the offset is supposed to be given after this definition. Depending on the lock status, three cases arise.

1. (no lock).

   • The basic point is highlighted.

   • The offset is requested in three dimensions (dx,dy,dz).

2. (plane lock)

   • The basic point is locked to the plane prior to the offset giving.

   • The u-v system with the locked point as origin and the coordinate axis parallel to the plane will be highlighted.

   • A two-dimension offset (du,dv) is requested to secure that the resulting point remains in the plane.

   • By typing <CR> the offset can be given in three dimensions, provided that the plane lock is not static.

3. (line lock)

   • The basic point is locked to the line prior to the offset giving.

   • The locked point and a direction vector along the line is highlighted.

   • A one-dimension offset (dl) is requested to secure that the resulting point remains on the line.

   • By typing <CR>, the offset can be given in three dimensions, provided that the line lock is not static. Selecting OC means that no offset will be added.
