How to rotate a sketch in Fusion

Solution:

Since the rotate function within the move/copy command does not allow for coplaner points as the axis center point, a 3D sketch line should be used to define the axis as described:

1. Edit the sketch required.
2. Enable 3D sketch from the sketch palette.
3. Draw a 3D line at the point which the axis starts.
4. Use Move/Copy and pick Rotate.
5. Select the newly created 3D line as the axis.
6. Rotate the sketch objects accordingly.

Note: Be aware of the constraints that are applied to the geometry of sketch automatically, and use "Move" command.
