Tagging Tutorial

You can use the attribute tagging mechanism in SketchUp to achieve some impressive effects in WalkAbout3d with very little effort.

First you need to install the Attribute Manager plugin in SketchUp, which lets you tag data to entities in SketchUp. The useful ones with respect to WalkAbout3d are Groups and Components.

To Turn off collisions on a group or component

  • Select the group/component, and right click and select Attribute->Show:
  • This will show the attributes dialog box; add an attribute category:


  • And call it WA3D:

  • Now you can add an attribute to this category by clicking on "Add an attribute", call the attribute Collide, and give it the value 0 and press the OK button:

  • Then click on the accept, to confirm the attribute changes

  • thats it, if you save the design and load it into Walkabout3d the group/component will no longer be "solid" and will allow you to walk straight through it. This is particularly useful for semi-transparent surfaces, or for doors to allow access into building (without having to open them in Sketchup).

To tag a surface as "water" in WalkAbout3d

  • First you must create a flat surface in Sketchup and place it in a group. The surface can be any shape and have holes in it but it must be perfectly flat.
  • Next follow the steps above to setup the WA3D attributes category.
  • Now instead of adding a "Collide" attribute, add a "Water" attribute and give it the value 1:


  • Save the design and load it into WalkAbout3d.There are some settings to control how water areas look in WalkAbout3d, they are in the settings dialog on the SketchUp page:


  • The settings are fairly self explanatory, and bit of experimentation will clarify them - and this is the end result (the still image doesn't do it justice!):



Link published files together in WalkAbout3d

You can now link obects in one published project to another published project. What this means is that when you are viewing a design you are able to point the mouse cursor at a "linked object" (the mouse cursor changes to a pointing finger), and click on the object. A pop-up menu appears describing the linked project. This can be achieved by the same tagging mechanism described above for any group or component. The following table shows the valid tags to be added to the WA3D category:

Name Value Description
Link filename The filename of the published file, then a ";" then the name of the scenario. Note: use "/" to delineate directories and filenames.
Menu description Any text yoou like to describe the link

An example is show below:

If you just add the Link tag and leave its value blank then when you load the SketchUp file into WalkAbout3d you will be asked to complete the link with the following dialog box:

This dialog box lets you find the prublished file you are looking for (press the "..." button), and then choose from the list of scenarios. It also lets you entre the menu text.

When publishing a file which contains links to other published files, the wpf file produced will contain ALL of the files - so all you need to do is send the one wpf file to your client. Alternatively use the new Single Exe publish function.


To animate a door to open in WalkAbout3d

  • This is achieved through the same tagging mechanism. The following table shows the valid tags to be added to the WA3D category:
Name Value Description
Door 1 tells Walkabout that the tagged component or group is a door
Type Hinged | Sliding | Revolving What type of door?
Side Left | Right Which side does it open on (not used for Revolving doors)
Axis Red | Green | Blue Which axis does the door rotate around (make sure you align your door to one of these
Mode Click | Distance How should it open? - with a mouse click or when the user approaches it
Distance number (metres) If opening when user approaches it - how near should the user be before it opens?
Angle number (degrees) How wide should it open ( not used for Revolving doors).


  • Just tag the door (it must be a component) in Sketchup with the above tags.
