Help me rotate/flip disc

[Turbine]

Here's my disc that I want to flip vertical:

Hard to explain, but the blue axis should be where the red axis is. So how do I do?

Hi Turbine (and welcome),

Now what would you like to do exactly? Flip(which would not change anything) or rotate (like to "stand the disc up vertically)?

Yes, make it stand vertically! Instead of lying on the flat side it should stand on the 1 mm edge.

EDIT: The flat side should also be in line with the red or green axis.

OK, the trick to align the rotate tool is as follows:

1. Click on one of the endpoints of your (segmented) circle where it crosses the red axis
2. DO NOT let the left mouse button go but drag the cursor along the red axis (the Rotate tool will turn into red showing when you are okay)
3. NOW let the left mouse button go (the rotate tool will "stick" in this position)
4. click anywhere and start rotating
5. release everything and type 90 then press Enter.
