Enhancements/ Additions:

• OpenGL version available.
• Picking has been improved, speed increased.
• Graphics speed has increased.
• 2D version available.
• Groups may now contain surfaces, curves, and/or points.
• A status indicator has been added to the GroupEditor to indicate the visibility of the group.
• Local refinement to the volume grid using line and point sources.
• Topology check takes into account volume grid boundary conditions.
• Hot keys added to adjust the view sensitivity, generate the volume grid, and exit. Items may be unpicked using the "Ctrl" key and the corresponding pick function/hot key.
• The key sequence for all hot keys associated with a button is listed on the button. The ^ symbol is used for the "Ctrl" key and the - for the "Alt" key.
• Image maps have been added to the documentation for easier navigation.

Bugs Fixed:

• Interior points and point spacings are saved to the IGES file.
• Vertices not attached to any geometry are saved to the IGES file.
• Point spacings may be applied to vertices not attached to any geometry.
• The Debug connectivity and surrounding neighbor maps are updated when the grid is changed
• Create elliptic curves by selecting two points and two vectors.
• Parameterization of surfaces of revolution and circular arcs are more uniform.
