I am a near total newb with a frustrating issue. Doing Blender Guru's tutorial making a donut and cup, I am trying to move the saucer in line with the cup/mug. It seems totally easy. I align it properly on the X&Y axes then proceed to move it on the Z using (G)(Z). Confusingly, it also moves forward on the X. I tried not touching the mouse and also hit the two keys at the same time thinking that I am nudging it. Time and again, it moves on multiple axes.
Thank you for the information on checking that I'm using Global. The problem persisted regardless. It appears that the issue was that I had 'Snap to' on. With the peek into the fact that there are multiple constraints, I'm working my way through the Udemy Blender Encyclopedia course to see the super basic stuff that I missed by jumping into online tutorials.
