I have existing objects that I've copied into Designer which are supposed to be isometric, but aren't quite (they're about 27.8 degrees from zero instead of 30). I would like to rotate these objects so they align with my isometric grid. I've tried all the permutations I can find, and the only way I can see is to rotate them until they appear to align with the grid. I would like to have something like a 'rotate to align to grid' tool.
I've attached an image to help explain, I want the screw to point along the same 30 degree angle that the grid lines are on.
Is there anything like this I can use?
