I was recently asked how a control handle can be added to a Visio shape so that it can be used to re-position the text block. Fortunately, it is extremely easy to setup, and requires just two formulas to be updated in the ShapeSheet. This is a great use of the SETATREF(…) function.
I recently had to revise my understanding of the POINTALONGPATH(…) function in Visio because I was getting a #REF! error in some cases. My particular scenario requires a line with a number of vertices that are initially all in a straight line but can be moved by dragging controls around that each vertex is bound to. My assumption had been that a segment of a path is always between vertices in a geometry section, but this is not the case. So, I thought I would look deeper into the ShapeSheet functions of paths and segments. The following screenshots show a series of ShapeSheet formulas and the result of them on a single line that has 4 vertices that can be moved using a yellow control that they are bound to. Notice how the PATHLENGTH(…) formula fails to understand the segment parameter until the vertices are moved.
In case the screenshots are a little dry, I have recorded a short video to explain further.
My own need was for a boundary shape around some other shapes where I wanted to make the segments disappear if they were outside of the Visio page. The unexpected #REF! values were causing distortions because the co-ordinates were failing to update.
However, I can see that this understanding of line segments and points will be useful in many types of diagrams.
For completeness, I thought I would try the same exercise with a PolyLineTo row rather than multiple LineTo rows.
The PolyLineTo formula does have the advantage of being a single row, but this means that the PATHLENGTH(…) function does not have a segment index to that can be used to calculate with. In fact a PolyLineTo row does have two segments, but the last one is always 0 length!
However, I was able to calculate the lengths of each segment in both cases, by using the co-ordinates of the Controls in the Tip cell for each Controls row with the SQRT(…) and POW(…) functions..
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…
I have used Visio’s Shape.BoundingBox(…) for many, many years and I cannot ever recall it failing, but I have now managed to create some shapes that cause it to error. This caused many hours of confusion, so I nearly abandoned using the method, until I discussed it with my fellow Visio MVP, John Goldsmith (see…
Many Visio diagrams get quite large, and sometimes it is useful to provide the ability to jump to another shape quickly in the same document, either on a different page or on the same one. Although there is an add-on provided in desktop Visio that is used by the Off-Page Reference shape provided in the…
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…
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…
Microsoft Visio desktop has the ability to display icons from a built-in list of Office icons on Actions and Action Tags (nee Smart Tags). These can be set in the ShapeSheet by using the desired number from several thousand in the ButtonFace cell. Although there is the ability to add better icons using code, the…
The desktop Visio editions, Visio Professional and Visio Plan 2, have a great way of automatically displaying data as Data Bars, Icon Sets, Text Callouts and Color by Value. The first three types of Data Graphics require sub-shapes to be inserted into each shape that they are applied to, but the last one, Color by Value (CBV), merely requires some User-defined Cells and formulas. However, unlike the first three, there can be only one Shape Data value displayed as colours in each Data Graphic (DG). So, how can we easily update the colour assigned to each value using code, rather than manually using the manual dialogs provided?
I was recently asked how to change the default font size and line weight in Visio, and then saw then many others are asking the same sort of question. I found one reasonable answer suggesting that you should create a new document from your required template, then edit the Styles to suit, and then save as a new personal template. Well, I am not sure I like that answer because it means you must create a duplicate template for each one you use. So, I decided to see if I could find a better way…
Firstly, it is important to know that these default settings are not editable for the whole Visio application, because they are stored in each document, under the Styles collection. You can view the Styles in a document using the Drawing Explorer window that can be opened from the Developer tab.
I recently revised my chess and checkerboard Visio documents to work in Visio for the Web (Visio Plan 1), but now that Microsoft are providing a version of Visio free to M365 business users, I need to make some further adjustment to get them to work for these users who do not have a Visio Plan 1 or Plan 2 license. The problem is that Microsoft restricts the capabilities of the free version by white-listing Visio masters. So, the answer is to delete the masters … then the Visio document becomes editable in Visio for M365!
So, what is the downside?
[Read more…] about Making Custom Shapes for Visio for M365A few years ago, I wrote an article about messaging and encryption inspired by a visit to the National Museum of Computing in the UK. I developed a Morse Click shape to demonstrate how Visio can be used to represent and learn Morse Code. However, I never published the shapes here, and my good friend John Marshall recently wrote an article about Braille in Visio, so I thought I should explain how I made the Morse Click shapes, and I took the opportunity to enhance the shapes with some accessibility features that I have learnt since I originally designed them. I have also changed the shapes to be Visio Web friendly, which means, for example, removing shape effects.
I think I learnt Morse Code as a Cub Scout, but forgotten it in the half-century since. Its evolution, and its use today still makes very interesting reading. Each letter comprises of between one and four short or long clicks, whilst each number has five such clicks. Generally, the most used letters have lesser clicks, with ET being the lowest number, presumably to save an extra terrestrial money on a phone call home!
There are just two master shapes of interest here, Morse Click and Morse Click Rack, and a couple of page Shape Data rows. The Morse Click shape can be anyone of the 36 characters with a simple Shape Data value change, whilst the Morse Click Rack is a list shape and can spell out the words of up to 26 Morse Click shapes within it.
