Inconsistent angle dimensioning with configurations

[Robert-FreEnergy]

Hello, I am modelling a tank that needs to have 6 configurations.

The differences in the configurations are the angles from datum, at which 3 pipes exit the tank.

These angles are defined as editable properties in the configuration window which are referenced by a sketch which is used to create planes in which orientate the pipes.

My problem is that sometimes these angles are clockwise from datum and sometimes these angles are anti-clockwise from datum, sometimes they are 180 degrees out. In the attached archive file the sketch in question is called "angles".

My question is, "Is there a method by which angles can by defined as clockwise or anti-clockwise and restricted so that the affected line does not flip through 180 degrees that is still configurable?"

Feels a bit weird to be replying to my own post, however, given this appears to have been viewed a number of times and I've spent the last couple of hours working out a solution, I might as well post it in case anyone else runs across the same problem.

I have changed the design to create the construction planes I use to create the pipes to be created independently of the sketch that was not being consistent with angle orientations.

I constructed the planes at an angle to the central axis of the tank, with the angle being defined by the variables that I can edit in the configured options.

This works and is consistent, I know this isn't necessarily a solution to the original problem, as the sketch dimensions are still inconsistently applied, but it does show that generally the solution to a problem with fusion is to just do it a different way.

That is a good solution @Robert-FreEnergy .  Construction plane orientations are deterministic, with a plane normal in a particular direction, so using them to define the angles in your sketch makes them to be more consistent.
