ive loaded a schematic and it has loaded, but i toggled the single layer mode and the schematic fully disappeared. i then used pgup and pgdn but nothing came up.
any fixes?

Did you check if there was something rendering at that y level since you need to go up/down till there is something for to render.

Use the Render Layers menu (or the layerSetHere hotkey if you have assigned it) to move the layer selection to your position. By default the values start from 0, so the single layer mode would be at y = 0.

ahhh i thought "y=0" was relative to your schematic. thank you :D

They are absolute world coordinates, because you can have an arbitrary number of placements loaded at once, so there isn't just a single schematic/placement to make it relative to. Personally I think I also kind of prefer it this way anyway.
