Hi,
Just discover the new tweak mode (edit sop) in H15.
I'm trying to use it in view space (like in the video from sideFX : https://www.sidefx.com/index.php?option=com_content&task=view&id=3158&Itemid=404) [sidefx.com]
Can't get it work, it only moves point on ZX plane (shift for Y). If i switch handle to view space, it works when using the handle (first selection, next use the view space handle) but not in tweak mode unfortunatly.
What am i doing wrong?

Thanks a lot !!

Edit: Found the answer (thanks Eisenhans). Uncheck viewport grid is the key to not auto snap to XZ plane
