Triad

See the whole job in one 3D scene. Bring your tanks, piping and imported files together, pick any part to read its properties, and share the model with your team or client.

A seat is needed to create and edit models. Viewing a model, including through a shared link, needs no seat. An organisation's admin decides who gets a seat.

Overview

A Triad model is a container. You add your cloud Tank Designer and cloud Piping Designer files, or import a PCF, CAESAR II, STL, DXF, DWG, STEP, IFC, IGES, OBJ or glTF file, and place each one in the scene by typing its coordinates (millimetres, Z up). One tank can stand in several places: it is built once and placed as many times as you need.

The model opens in the browser with a Selection tree on the left and a read-only Properties window on the right, the same way you would review a plant model in a desktop viewer, with nothing to install.

Key Features

Selection Tree

Every file, location, group and part is a row you can hide, show or colour. Hiding or colouring a node covers everything below it, and double-clicking zooms to it.

Properties

Click a part in the tree or in the 3D view and read what the source file knows about it: nozzle size and elevation, pipe diameter and schedule, valve tag, material, spool. Properties are read-only, with a link back to the native file.

Your Own View

Editors save the model's default view. Everyone else can hide and colour parts for themselves, and those choices are kept for them without changing the model for anyone else.

Linked Documents

A linked CTD or CPD is copied into the model. When the original changes, editors see a small marker and can review what changed before updating the copy, so a shared model never changes by surprise.

PCF and CAESAR II Files

Import a PCF file (pipes, elbows, tees, reducers, valves, flanges and supports, with their attributes) or a CAESAR II neutral file and see it in the same scene as the rest of the job.

3D Files from Other Programs

Import STL, DXF (2D drawings and 3D faces), DWG, STEP, IFC, IGES, OBJ and glTF files. STEP keeps its assembly names and colours, and IFC its storeys, classes, materials and property sets. Big files convert in the background while you keep working.

Place, Turn and Scale

Say where an imported model goes when you import it, then move, rotate about X, Y and Z and scale it from the Properties window. The same file can be placed again as many times as you need.

Large Models

Parts are drawn in batches, so a scene with thousands of pipes, several tanks and a CAESAR II model stays responsive in an ordinary browser.

How It Works

1
Gather

Add the project's tanks and piping, or import PCF and CAESAR II files, and place them by coordinates.

2
Review

Walk the tree, hide what is in the way, colour what matters and read the properties of any part.

3
Share

Send a read-only link, or include the model in a transmittal to your client at a fixed revision.

Revisions and Sharing

  • Revisions: A Triad model has the same alpha revisions as every other document. Each revision is a complete snapshot, and earlier revisions open read-only.
  • Signed links: Share a read-only viewer by email. The link works for 7 days by default (you can choose up to 90) and recipients need no account.
  • Transmittals: Send a Triad model to a client in a transmittal. The client opens exactly the revision that was sent.
  • Add-on: Triad is sold separately from the plans, for a single user or for a whole organisation.
