Running low level pipe work and changing it to high level on the same floor??

Is it possible to run low level pipe work and then have it rise up to high level (ceiling Void)???. For context , the pipe work is serving the building at low level and when it entres the building it rises up to high level within the ceiling void. Is the a way to do this or do you have to draw the full pipe network at one constant level, IE low level or at high level?????

When I draw the pipe work at low level and then change it to ceiling level when it entres the building , the pipe work looks like it is at an angle or slopping up instead of having a nice 90 degree upward transiton from ll to hl.

Any help on this matter is greatly appreciated.

Kind Regards
