I'm trying to use guides to align objects for an isometric design. I use the shapesheet to set the angle to -30 and the guide changes, no problem. But now I can't get shapes to snap or glue to the modified guides, though they will snap and glue to unmodified guides. I compared the shapesheets of a modified and unmodified guide and don't see anything different except the x/y location on the sheet. What am I missing here? Is this a bug or just a problem with the end user, aka me?
