See attached pictures. My fittings are detach from the pipe when I try to move it and snap to equipment.
I have tried all kinds of ortho + snap setting, but the fittings will not work as stated in the manual.
To move it in that type of scenario I use point filter. Keep the nearest osnap on, grab the center grip on the main run, use the point filter for the main run of pipe, and then pick the nozzle you want to line it up with. pick the center grip on the tee for the last point filter prompt and it should move to the correct location.
the point you pick to move the fitting to needs to be a point on the actual line.
I would pick the centre grip node on the tee then
shift+rmb pick the 'from' snap
pick the centre of the flange on the equipment as your from point
shift+rmb pick the 'perpendicular' snap
pick the pipe line with the tee in it pretty much anywhere on its length
filters will work also, but I find the 'from' snap VERY handy
