Dynamic alignment guides

When you drag activities to move them, alignment guides will automatically appear in the canvas. You can also use the arrow keys to move single activities, but the guides don’t appear.

Alignment tool options

Alternatively you can highlight multiple activities and use the ‘align and distribute’ icon on the top bar to quickly tidy up diagrams. Note that you need to select a reference object, and then (on Windows) shift-select the rest or (on OS-X) cmd-select the other objects.

Sizing tool options

The next icon to the right allows you to quickly match height and/or width of activities (again, select your reference activity, and then ctrl/cmd select the scope of activities to match).

Note: In both cases you can “drag select” a range of objects, but if that re-selects your reference object, it will change the size/alignment to the lowest numbered activity box. So, select and ctrl/cmd drag works, but only if you are not re-selecting the reference.


The activity box numbers don’t have any meaning, but they do form the basis of level numbering and visual appeal, as people normally like to see the completed diagram with some logical numbering. In the Pro version there is rules based renumbering functionality based on alignment (top to bottom, left to right).

In the free version, you can still renumber, but it is manual and you cannot change to a number that already exists on the diagram.

If you right click on an activity box, select "Change number". You cannot use a number that is already in use. So if you had 1,4,3,2 you couldn’t renumber box 4 to 2 straight away. You have to right click on 2 – use an unused number (e.g. 12) then renumber box 4 to 2, box 12 to 4.

This simple approach makes it less of a mind-game puzzle and a little less painful:

Change the highest numbered box that you want to change and renumber it by adding 100 to the current number.

Then, work from highest to lowest numbered activity box and renumber using RightMouseClick | renumber

Example one: you have boxes numbered 1,2,3,8,4,5,6,7 in your flow. (Usually you decide to add a box into a flow – this is the result.)

Here, you would change 8 to 108, then 7 to 8, 6 to 7 etc… then once you have changed 4 to 5, you can change 108 to 4. 

Example two: you have boxes numbered 1,2,3,5,4,6,7,8 in your flow (i.e. you want to change numbers in the middle of a sequence).

Here, you would change 5 to 105, then 4 to 5 and you are free to change change 105 to 4. 

You can Auto Renumber if you are a PRO Space
