Mirror in sketch from axes

[roambotics_scott]

Very often I want to mirror something in a sketch off of the center line based on the global origin / axes. 

Currently I have to add an extra stray line to the sketch.

Instead, we should just be able to use the origin axes (preferably without having to select and show them)

It is a good news that this feature added to the new version of Fusion-360, but it is still not found in Inventor

I thing you have to add this enhancement to Inventor also.

If the axis you want to use is not in the same plane as the Sketch, then you can project the axis into the Sketch, or you can select the Origin Plane which contains the axis you want to use.  Either way you end up with a projected line in your Sketch which is used for mirroring.
