Overview

cloud Piping Designer (CPD) is a browser-based 3D piping isometric design tool. Build piping networks by placing nodes and connecting them with elements — pipes, elbows, flanges, valves, reducers, and more. The 3D scene renders in real time using WebGL, with orbit controls for pan, zoom, and rotate.

Every design is revision controlled and stored securely in the cloud. Export to industry-standard PCF (IsoGen) or CII (Caesar II) formats, share via secure viewer links, and maintain a complete design history — all from your browser.

Key Features

3D Piping Design

Add nodes and elements — pipes, elbows, flanges, valves, reducers, bellows, couplings, instruments, and miscellaneous components. Real-time 3D visualization with orbit camera controls, cursor-centred zoom and zoom extends.

Pipe Supports

Attach supports to any node — Anchor, Rest, Guide, Line Stop, Spring Can, or Spring Hanger. Up to 6 supports per node, each with 3D visual representation and direction vectors.

Dual Revision System

Alpha mode (A, B, C...) for work-in-progress drafts. Promote to numeric mode (Rev 0, 1, 2...) for formal issued-for-construction documents. Full revision history with descriptions.

PCF & CII Export

Export to PCF (Piping Component File for IsoGen isometric drawings) or CII (Caesar II Input for pipe stress analysis). Includes materials list, schedule-based wall thickness, and support key mapping.

Tees & Olets

Insert a real Tee with C and M dimensions and a branch size, then re-open it any time to edit them or re-aim the branch with dX/dY/dZ. Convert a welded junction into a Tee with a double-click.

Copy & Paste

Select a run of elements, pick a reference node and paste it onto one or many nodes. The copy is welded on by its reference node and the whole paste undoes in one step.

Rotate a Section

Turn a connected section about an end node around global X, Y or Z or an axis through two nodes. Optionally carry the piping beyond it rigidly, with warnings for supports and eccentric reducers.

PCF Import

Bring an IsoGen PCF into the editor as live geometry, including Tee branches. Replace or append, weld to an existing node or place by coordinates, with a persistent list of import warnings.

Pipe Schedules

Every element carries a B36.10 schedule with the wall shown beside the size, so PCF and CII exports use the right wall thickness and keep different schedules as separate materials.

Multi-Select & Edit

Ctrl-click or Shift-click a path of nodes or elements, then delete, edit, copy or rotate them from the right-click or long-press menu. On a touch screen, the rail Multi-select button lets you tap several items.

Screenshot Thumbnails

Auto-generated PNG thumbnails on every save. Displayed in the project index for quick visual identification of designs without opening each file.

Secure Sharing

Share read-only 3D viewers via signed URLs (7-day expiry). All editing tools are hidden in viewer mode. No account required for recipients.

How It Works

1
Build Your Model

Place nodes in 3D space and connect them with pipe elements. Add elbows by double-clicking nodes, insert supports, and configure sizes from DN50 to DN1050.

2
Save & Revise

Save your design with an auto-captured screenshot thumbnail. Create new revisions as your design evolves. Promote alpha drafts to formal numeric revisions.

3
Export & Share

Export to PCF for isometric drawings or CII for stress analysis. Share a read-only viewer link with your team or submit through the project workflow.

3D Engine

The design environment is powered by Three.js WebGL rendering with full orbital camera controls:

  • Element types: Pipe, Elbow (1D–5D radius), Tee, Flange, Valve, Reducer (Concentric, Eccentric Flat Top/Bottom), Bellow, Coupling, Instrument, Misc
  • Support types: Anchor, Rest, Guide, Line Stop, Spring Can, Spring Hanger — up to 6 per node
  • Node insertion: Double-click any pipe element to insert intermediate nodes (auto-splits the element)
  • Labels: Toggle overlays for Node ID, Element ID, Length, Diameter, and Bend Radius
  • Customization: Per-component color scheme, absolute coordinate system, multiple piping systems per file
  • Import & export: PCF and CAESAR II (.cii) import, PCF (IsoGen) export with SKEY support mapping, CII (CAESAR II 13.0 neutral file) with B36.10 wall thickness per schedule
  • Navigation: small steady wheel-zoom towards the cursor, an orange reference dot to zoom, rotate and pan around, selection as the pivot, touch gestures

Editing & Model Checks

  • Multiple piping systems: One file can hold several independent runs, each with its own origin and optional reference-node offset. A new origin is registered automatically if a delete splits a run.
  • Editing tools: Multi-select, copy and paste by reference node, rotate a section about an end node, edit a Tee's C, M and branch vector, and undo/redo with Ctrl+Z / Ctrl+Y.
  • Pipe schedules: Each element carries a B36.10 schedule (default STD); the wall thickness follows the size and schedule into the PCF and CII exports.
  • Geometry checks: Elbows validate the straight pipe on both sides and shorten the neighbouring elements; a reducer's outlet size cascades to the piping downstream.
  • Revisions & locking: Alpha and numeric revisions with a mandatory description; the file is locked while a review workflow is open, and older revisions open read-only.
  • Sharing: A signed read-only 3D viewer link (7-day expiry) with every editing tool hidden — no account needed.
