Instrument that indicates all points of view (7)
I believe the answer is:
compass
'instrument' is the definition.
(I know that compass is a type of drafting instrument)
'all points of view' is the wordplay.
I cannot quite see how this works, but
'points' could be 'ss' (an abbreviation for a compass point written twice) and 'ss' is located in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'that indicates' is the link.
Can you help me to learn more?
(Other definitions for compass that I've seen before include "Direction finding instrument - range" , "Direction finder; scope" , "Range, scope" , "Range - vessel's navigating instrument" , "where all points considered?" .)
