OpenIso
Lightweight Isometric Piping Symbol Editor
OpenIso is a lightweight, open-source graphical editor designed for creating and managing piping isometric fitting symbols. It bridges the gap between manual sketching and complex CAD suites, providing a streamlined environment for designing Symbol Keys (Skeys) and component graphics used in industrial piping software like AVEVA PDMS/E3D or Intergraph Smart 3D.
Features
- Format Interoperability: Import and view symbols from ASCII (Intergraph) and IDF (AVEVA) files.
- Precision Connectors: Define critical piping points:
Arrive,Leave,Tee, andSpindle. - Vector Toolset: Specialized primitives for skeys:
- Lines, Rectangles, Rhombus, Circle, Ellipses, Triangles, Caps (Arcs), Hexagons.
- Hatching and Solid Color Fills.
- Modern Export: Save symbols in ASCII format for integration with modern piping tools.
- Globalized: Full localization support via Crowdin.
Supported Symbol Keys (Skeys)
OpenIso allows you to define and edit standard SKEY types used in isometric generation:
| Category | Skey Examples | Description |
|---|---|---|
| Valves | VAVW, VAGL, VACK |
Gate, Globe, and Check valves |
| Fittings | ELBW, TEBW, REDC |
Elbows, Tees, and Concentric Reducers |
| Supports | HNGR, GUID, STOP |
Pipe hangers and supports |
| Instruments | INST, FLME |
Inline instruments and Flow meters |
| Special | CAPW, FLRF |
Caps and Raised Face Flanges |
Symbol Anatomy
OpenIso focuses on the logical structure of a piping component. Each symbol is defined by its geometry and functional connection points.
- Arrive & Leave: Define the primary flow path through the component.
- Spindle: The orientation point for valve handles or actuators.
- Tee: (Not shown) Used for branching components.
