Rotate Lighting fixture with asymmetrical IES data

[Anonymous]

I have a problem with a lighting fixture. It is a fixture placed at the ceiling where lighting is directed towards the wall. To be used lighting up blackboards and so on. I have tried almost everything but if I rotate the lighting fixture the light still goes in the old (1.) direction. The symbol of the light is turned as expected but lights in renderings doesn't change at all. 

If I test with a symmetric IES file it works just fine.

One thing I have noticed is that when rotated In plan view (around z-axis) it seems like the lighting is rotated around x or y-axis as well.

If I tilt the IES file it is even worse.

Has anyone had the same experience and maybe found a solution.

Consider uploading your lighting family so we can have a look what you have so far.

RFA and IES file is here - Zipped

Check Work Plane Based and uncheck Always Vertical in the Family

...Wrong file. I was referring to your last file.  Your first is ceiling mount. I unclear what the issue is now. Seems to be responding to tilt angle properly.

Yes I agree there is some response accordint to tiltangle. It seems to make it even worse.

I have created a family in which I manually can rotate the IES file in any direction (3-axial). File attached. It seems like Revit can't read the IES file correctly. Rotation angle 1 works, angle 2 flips between 90 and 270 (try 89 an 91 degrees) and angle 3 makes no difference at all.

I have tried with other IES files (symmetrical works as expected but all assymetrical seems to acht the same).

Could anyone provide me with a family that works with an assymetrical IES file included?

I turns out that it's a problem in Revit 2017. (No fix to this is planned).

Thanks to you who took your time to respond to this issue.

Note:

I took me several hours to test and a lot of emails to convince the support team that there was a problem and to get them to accept that the problem exist. Autocad support is not really that helpful trying to understand the problems users experience. My experience is that the first answer always is trying to ignore the problem. In this case the first response was that they do not help on creating families!!!
