Cannot delete floor slab sub element points?

[graphite]

I am trying to delete floor slab sub element points but to my surprise I don't have the option to do this nor does the delete key work. Any thoughts?

It does work, try a window selection on the point maybe then press delete.

You can delete the points only in Modify Sub Elements mode and only the points that have been manually created. Corners and points where the floor boundary line has been split, cannot be deleted. You can only reset shape to remove all.

Altering the limit of the slab (ie the shape) will reset all of the sub element points too. You can always edit the shape, move one edge out a bit, finish the editor and it will reset the points, then re-edit it back in place.
