Pressure Network

Potable water, firefighting, irrigation and rising mains: from polylines to a designed, checked pressure network with profiles, crossings, valve boxes and catalog parts.

7 tools
Create Pressure Network icon

Create Pressure Network

ZIPRESSURENET

Turns the route polylines into pressure pipe runs at a fixed cover below the surface.

  • Draw the routes, pick them, and the whole network is built in one step instead of run by run.
  • Parts list, size and style are chosen once for every polyline.
  • The cover follows the ground along the whole route, so the first model is already at the right depth.
Profile icon

Profile

ZIPROFILE

Draws the profile views of many pipe runs at once, with the surfaces, styles and band set you choose.

  • Tens of profile views in one go instead of one wizard per run.
  • You set the gap between views, measured from the lowest band, so the views and bands never overlap.
  • The same styles on every view, ready for the drawing sheets.
Crossing icon

Crossing

ZICROSSING

Shows every pipe that crosses the chosen runs inside their profile views.

  • All crossing pipes appear in all profiles in one step, with an override style that stands out.
  • No more projecting crossings by hand view by view before a coordination meeting.
  • Crossing solids are projected too, for clear crossing details on the sheets.
Create Part icon

Create Part

ZICREATEPART

Draws a hollow 3D solid of an elbow, tee, reduced tee, reducer or cap from its sizes.

  • Make the fitting that is missing from the catalog from its real dimensions.
  • The solid is ready to become a catalog part, so the model uses the real fitting and not a stand in.
Surface Box icon

Surface Box

ZISURFBOX

Places a riser and a surface box over every valve of a pressure network, up to the surface.

  • All the valves of the network are done at once, each one up to the finished ground.
  • The boxes show in the profile views and are counted in the BOQ.
Design check icon

Design check

ZIPRESSCHECK

Checks one or several pressure networks against your design criteria.

  • Cover, slope, length, deflection and more checked in seconds for the whole network.
  • Every error in one list: click it and the drawing zooms to the part.
  • Export the list to Excel as the QA record of the design before issue.
Edit icon

Edit

ZIPRESSEDIT

Every part of a pressure network, grouped by pipe run, in one list you can edit.

  • Edit on drawing: point at any part in the plan to read its values, click to change them directly on the drawing.
  • Draw vertical: draw risers and vertical pipes in a vertical plane with a live preview; they become pipes with the right bends from the parts list.
  • Merge or split networks, promote many data shortcut networks at once, and place valve chambers.
  • Change names, levels and slopes of many parts together, with Undo.

Pipe Network

Storm, sanitary and sewer: from polylines and level texts to a full gravity network, then profiles, drops, house connections, design checks and editing in one list.

9 tools
Create Pipe Network icon

Create Pipe Network

ZIGRAVITYNET

Turns polylines into a gravity pipe network, reading the invert and slope texts of the drawing.

  • The designer's layout with its level texts becomes a full network in minutes.
  • Each pipe starts at its invert text and falls by its slope text; a manhole is placed at every vertex.
  • No typing of inverts pipe by pipe, and no mistakes copying levels from the drawing.
Profile icon

Profile

ZIGRAVPROFILE

Draws the profile views of many gravity runs at once, with your surfaces, styles and band set.

  • Every run of the network gets its profile in one step.
  • The gap between views is measured with the bands, so the sheets come out clean.
  • Same styles and band set everywhere, ready for plan and profile sheets.
Crossing icon

Crossing

ZIGRAVCROSSING

Shows the pipes that cross the chosen gravity runs inside their profile views.

  • All crossings in all profiles at once, with an override style.
  • See the clearance to every crossing service before you fix the levels.
  • Crossing solids projected for the crossing details.
Structure Drop icon

Structure Drop

ZIDROP

Lists every drop in a pipe network and draws a back drop box against the manhole.

  • Find every drop of the network without going manhole by manhole.
  • Zoom to each one from the list and draw its back drop in a click.
  • The back drops are counted in the BOQ.
House Connection icon

House Connection

ZIHOUSECONN

Joins house connection points to the nearest manhole with the chosen pipe and slope.

  • Pick all the connection points and the connections are built together.
  • Each one comes in above the highest invert of the manhole, so no connection enters below the main flow.
  • Hundreds of connections on a residential scheme in minutes.
Alignment icon

Alignment

ZIPIPEALIGN

Makes an alignment along the pipes and structures between two structures you pick.

  • Pick the first and the last manhole; the path between them is found for you.
  • A ready alignment for profiles and labels without drawing it by hand.
Part Builder icon

Part Builder

ZIPARTBUILDER

Edits the values of a part in the pipe network catalog in one window.

  • Lists, ranges, constants and the size table of a part, all in one place.
  • A drawing shows which dimensions change, so you know what you edit.
  • Adjust catalog parts to the project specification without the long Part Builder routine.
Design check icon

Design check

ZINETCHECK

Checks one or several pipe networks against your design criteria.

  • Slope, length, cover, drops, reverse slopes, outlet higher than inlet and more, for the whole network.
  • Every error in one list: click it and the drawing zooms to it.
  • Export to Excel as the QA record before issue.
Edit icon

Edit

ZINETEDIT

Every structure of a pipe network with its connected pipes in one list you can edit.

  • Edit on drawing: point at a structure or pipe in plan to see its values and connected pipes, click to change them directly on the drawing.
  • Change names, rims, sumps, inverts and slopes of many parts together, with Undo.
  • Merge or split networks, promote many data shortcut networks at once, apply rules, rotate structures and bulk edit.
  • Zoom to any part from the list.

M.Swap

ZIMULTISWAP

Swaps many pipe network and pressure network parts at once.
