Hi, I’m new to 3D design, so please be understanding, but I do not know where I’m making a mistake. I set the object on the grid to make it easier to draw internal objects. Unfortunately, from time to time, the entire object moves in relation to the grid. I do not know, maybe I have a function that I can not see, but I do not understand why this is happening. The program itself is quite intuitive, even for a beginner, but I do not understand this rotation on the grid. I uploaded the photo, to show this.
