I am trying to resize a very long, and at a certain point a yellow outline appears around the part I am resizing and it does not let me make the part any bigger (in that direction). Is there any way to extend these bounds outwards?
This bounds show you that you reached max part size (2048), and you can’t resize it more.
Also you can see this bounds if you trying to resize part to value <= 0. In this case, it will set part size to your snap to grid.
