What determines slicer dip azimuth when slicing in plan view?

I'm slicing often in plan view and I can't figure out how to always get the same rough dip azimuth when slicing - I'm either getting the desired dip azimuth or +180 to it. I always slice in the same direction - roughly North to South. I'm trying to avoid checking the dip azimuth and changing it when it's 180 degrees away each time I slice.

    From some basic testing now (I haven't really thought about this until this point) it's the direction that you draw in. And it's only really when you are in plan view that this matters.. If not in plan view it seems to be the top of the slice / plane that returns the dip azimuth.. So for when you need this take the following into consideration.

    Assuming plan view here:

    Draw from left to right on the screen will return around 0°, the plane / slice faces north, meaning if you Look At (L) the slice you will look south.

    Drawing from right to left is the 180° of the above as you might expect. This is what the hotkey Ctrl+N (Slice Y axis) will return.

    Draw Top to Bottom (N-S) will return around 90° (slice / plane faces West and you will Look east if using the Look At function) and bottom to top (S-N) around 270° (also Ctrl+E, slice X axis).

    Hope that helped, and remember that you could always Save the slice by Creating a Set in the slice preferences (bottom right by default).

    The only way is forward!
  • I didn't get the same result as you. I found that slicing on the left half of the screen (in plan view) will usually result in values 180-360, and slicing on the right half will usually result in 0-180. But there are exceptions, if I try to slice at around 177 on the right half of the screen, it will result in 357. Either way, thanks for your reply Niklas.

    Just so that we are talking about the same thing I'll add an image:

    If I create the slice (click and drag) on the green arrow I get around 0° and if I follow the purple line I get around 180° for the dip azimuth..

    Relative side on the screen does not seem to matter.
