Perspective Grid on All Sides

  • Hi, I'm not a particularly good artist. That's why I am interested in Clip Studio Paint, because it seems to have a lot of tools to help those of us who are not so skilled. One of those tools is the perspective grid.

    What I'm trying to do is to draw a one-point perspective image. Let's say it's a room with a floor and a ceiling. So I create a perspective ruler. And I show the grid, and the snapping seems a bit finicky, but I'll deal with that later. The problem is, the grid only shows for the floor. I need a grid for the ceiling, as well. I can't figure out how to make that happen. The only thing I can think to do is to rotate the layer 180 degrees, but that's ridiculous. I have the same issue with the Y-axis grid showing only on the right side; I need it on the left.

    Please help.
