This free lisp is useful while working with Land CAD Drawings. We received lots of drawing files where entities were behaving weirdly. Upon looking deep into the problem, we realised that many entities had got created in different UCS and they had some value in extrusion length. This lisp was developed to fix that issue; this free lisp will set the UCS value of all the drawing entities to default value. Note that by running this lisp on normal drawing, you will not observe any change and when you run it on drawings which are corrupted, most of the entities get recovered. Some entities will get dislocated. After running this program you will find the entities in the drawing will have normal behaviour.
