qP&S

Draw a drainage system in a fraction of the time

The heart of qP&S is a set of commands that draw sanitary and vent pipework the way an engineer thinks about it — by run and by junction — instead of one segment and one fitting at a time:

• Draw Sanitary — connect a fixture or a horizontal run into a sloped main or a vertical riser in a couple of picks. The branch inherits pipe type, system type and slope from the main you picked, and the junction closes with a wye / swept tee plus a 45° elbow pulled from the pipe type's routing preferences.
• Draw Vent — pick the vent main, then the drain pipe or the P-trap. The tool routes the riser up, runs across to the main and taps it with a tee; click near a free end of the main and it finishes with an elbow instead. No slope, families follow your settings.
• Quick Connect — join a branch into a main sitting at a different elevation. Every feasible 45° elbow + wye topology is solved and offered, so the junction closes cleanly instead of leaving a disconnected stub behind.
• Adjust Slope, Auto 2×45, Fix 90°, Align Z — re-slope a run, jump an obstruction with a pair of 45s, or straighten a bend, with the neighbouring fittings healed rather than orphaned.
