Riser

Riser places a vertical stack through every level with one click: a cold and hot water supply, or a rainwater stack. Its systems are chosen beside the tools before the click.

What it is

A riser is a vertical stack that stands through every level of the project. Its tool places one with a single click. The list beside the tools chooses what it carries: the cold and hot water supply together, or the rainwater. The stack that carries the waste water is a riser too, but it has a tool of its own, Soil stack.

When to use it

Bringing the water supply up through the floors of a building.
Placing a rainwater stack that takes the rain down from the roof.

The steps

Take the tool. Press K, or pick it on the toolbar, where it shares a button with the other plumbing tools. The status bar says to click to place a stack through every level, its systems from the list.
Choose what it carries. Pick Cold + hot supply or Rainwater in the list beside the tools.
Click where it stands. The magnet holds the click on the nearest point within reach, such as a wall's corner. The riser is placed there, through every level. Each click places another.

What it refuses

Nothing at the click. A riser is placed wherever you click. The project says on its panel when it stands in a column, a beam or an opening.

What it writes to the contract

One new entry at the end of the project's list of risers, as one step that one undo takes back: its point in metres, the systems it carries (cold and hot, or rainwater), and the phase the view draws in. It names no level, since it stands through all of them.

Common questions

Is the soil stack a riser too?

Yes, a riser carrying soil and waste, but it has its own tool: Soil stack. The Riser tool covers the supply and the rainwater.

Do I place a riser on each level?

No. One riser stands through every level of the project from the point you click.
