Origin not adjusting...?

Always trying to be a positive memeber on Blender society still these things run me nuts though:
How adjust Origin /Coordinate System 0,0,0/ to aligh with an object local axes - here tripod is a bit skewed, cant force it to align per/paralelly to object local axes /or normals/ ?


snap cursor to selection > origin to cursor ?

You are not clear with what exactly you are trying to achieve.

If you want to align the local axis of an object to a normal of a face you can use the Precise Align Addon.
