VisualLogidraw, Fault Trees using Microsoft Visio


Screenshot of VisualLogidraw

General Features

New version of Logidraw built as an Add-In for Microsoft Visio. Supports Visio 2003 and later.

Fault trees are an ideal way to represent the results of hazard analyses and Logidraw provides the perfect tool for minimising the effort in drawing such diagrams.

Logidraw allows hazard analysts and process engineers to exchange analyses more quickly and efficiently.

  • Visio based drawing tool for fault tree diagrams
  • Fully automatic left to right layout
  • Automatic checking of Logic validity
  • Automatic input sensitivity calculation

Currently, VisualLogidraw only supports Fault Trees and not Event Trees.

New features

  • Combines the rich functionality of Visio with the automatic layout functionality of Logidraw
  • Copy, cut, move, and paste fault tree logic to any part of the Visio drawing. Then use the automatic ‘fix layout’ action to layout the diagram
  • Copy and paste any part of the fault tree logic into Word and most other Windows applications
  • Change fonts, line colours and styles, background colour, input and gate spacing, label orientation etc. It is also possible to use a different shape palette rather than modify the supplied one
  • Use Visio to add arbitrary diagram annotation, background images etc. to your fault tree diagrams
  • Create a standard template file, and save your favourite display and layout settings for next time
  • Logic can be constructed on multiple pages
  • Use the inbuilt capabilities of Visio to print to 1 sheet or span across multiple sheets
  • Export to Logidraw LDR file format

Benefits include

  • New version improves flexibility of models created in Logidraw
  • A common fault tree that maximises the involvement of others and helps develop a correct hazard analysis
  • Saves time by eliminating tedious manual drawing and redrawing of fault trees as they are developed and modified
  • Hazard analysis is always logically valid because Logidraw allows only logically feasible combinations of events
