Many selection conversions have no effect.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The following selection conversions do not work:
a. Converting a (cell or point) (threshold or frustum or location) selection to a block selection does not select block(s) containing the points or cells.
b. Converting a block selection to a (global ID or index) selection does not produce a list of points or cells in each selected block.
All of the conversions above produce an empty selection of the new type. This is counterintuitive and undo/redo does not appear to include changes to the selection so there is no way to revert to the previous selection.
