Use this command to delete selected edges. This command works similar to the Melt command, the difference being, that unnecessary points will also be deleted automatically. This command is also ideal for deleting edges created using the Connect Points/Edges command.
If the Shift key is pressed when Dissolve is applied, all unnecessary Points, regardless of Phong Angle, will be deleted.
When in Point or Polygon mode, Dissolve functions exactly like the Melt command.
