A visual exploration of Penrose Tiling in Visio

Maybe it is because I used to be a building architect, but I have always been fascinated by the relationship between numbers and visualisations. Perhaps the most famous one is the Golden Ratio which has been used as the basis of many building designs and art pieces. It is often recognised to create a harmony that is universally understood, and is repeatedly found in nature, yet it all boils down to a simple ratio of about 1.618 … and is related to the Fibonacci Numbers. Roger Penrose (re-)discovered shapes based on the Golden Ratio can be arranged aperiodically on an infinite canvas without a repeating pattern. These Penrose Tiling shapes were developed into two groups (P2 and P3) each with two shapes.

There are rules about the arrangement to ensure that they do not fall into a repeatable series. These rules can be followed by ensuring that the ends of the arcs within each shape meet each other. The shapes can be used to try to create an aperiodic pattern of an infinite size, and then a timer can randomly change the colours. It’s a little festive fun!

Are Master Shortcuts useful in Visio?

Many Visio users may not even understand the question, but this almost hidden feature has been available for many years. A Master Shortcut looks like a normal Master in a stencil, but it is merely holds a reference to another Master in a Stencil, not necessarily the same one, and has an option to add actions that can change properties of the target Master when it is dropped on the page. The advantage is that the shapes on the page are still instances of the target Master in the document which makes customisation and maintenance much easier. So, why would you use them?

One good reason is that you are providing a custom stencil, but you want to include some of the built-in Microsoft ones. Just including a Master Shortcut to the Microsoft Stencil and Master does not break any copyright laws that I am aware of.

Another good reason is that many users prefer to just drag’n’drop a Master from a Stencil rather than further mouse clicks to configure the dropped shape with the Shape Data window or the right mouse actions.

This article describes how to use Master Shortcuts using BPMN shapes as an example.

  • The BPMN Task has 10 types available from Shape Data window and context menu
  • Copy Master then Paste Shortcut into an editable Stencil
  • Edit Master Shortcut Properties and rename, then copy/paste as required
  • Multiple Master Shortcuts but only one Master

Co-authoring and Commenting with Visio Documents

Microsoft Visio can be used in the web browser and on the desktop, but there are several licensing options available, so which ones can be used concurrently whilst supporting co-authoring and commenting? This article tests the various scenarios but assumes that the Visio documents are stored in OneDrive for Business or SharePoint Online\Teams. The Microsoft article, Work together on Visio drawings, explains most of the scenarios, but does not clearly explain the scope of the Visio web licenses with respect to diagram types or customisations.

Fixing dimensions of 2D shapes

I am often asked what makes Visio unique and makes it stand out from the crowd, especially in today’s online world. Well, I think there are many reasons, but one of them is the ability to create scaled drawings with parametric components of specific dimensions. This was crucial for my adoption of Visio back in 1996 (see Chase Manhattan Bank – bVisual ), and since then I have created hundreds of dimensionally accurate catalogue components for use in scaled drawings for multiple manufacturers. Over the years, I have developed some patterns in ShapeSheet formulas that I re-use consistently. In this article I show the pattern that I use to provide a user with specific width and height dimensions that can be selected in any of three ways:

  1. Manual resize of the shape with the shape handles to only the specified sizes
  2. Selecting a dimension from the Shape Data panel
  3. Selecting a dimension from the right-mouse Actions context menu

All of these options are linked together so that editing the list of specific sizes are easy to maintain.

  • Resize manually
  • Select a Shape Data value
  • Select a context menu Action

Merging Linked Data from Similar Tables

I was recently asked how to link data from different tables but with similar column names to Visio shapes. In this case, each table has the same unique identifier, but some of the column names are the same. The problem is that the data linking matches the column name with the label of a Shape Data row label, so the shared columns were updated with the values from the last linked data recordset. In this article I present a simple way that this restriction can be overcome.

Smart Radio Buttons and Check Boxes in Visio

A recent project requires an interactive tutorial within Microsoft Visio desktop where a lot of the questions need a single answer using radio buttons, or multiple-choice answers using check boxes. I thought that this would be a great use of the list containers capability because the questions and answers could be part of the container shape whilst the individual questions are presented as items in the list and automatically inheriting their particular question text from the containing list shape. So, this article provides these smart master shapes, and explains how they are built.

  • In Tutor mode, the Questions, Answers, Explanation and More Info can be edited
  • In normal mode, the Questions are presented unmarked and without explanation
  • Incorrect answers are marked with a red cross. An explanation and optional more info hyperlink is available
  • Correct answers are marked with a green tick. An explanation and optional more info hyperlink is available.
