  This example briefly describes how you can use the Step names that you used in Creo Illustrate sequence definitions to drive a corresponding step instruction/description in your experience. This is an unsupported, preliminary solution - R&D is working on a better, final solution. But as long as this is not available, you can use this one for PoC and demo purposes. To setup the scene: Here is what I meant with Step names that you used in Creo Illustrate: Now in Thingworx Studio you want to have the following result: The text is rendered with a simple Label widget. You'll have to remember the ID of this widget for the following javascript tweak. Add the following text to the Javascript section of your View: var labelId = "label-1"; // ID of the Label widget that displays the Step progress and description  text // this $on event handler switches the label based on the the sequence definition // the arg variable is of the following form: (<step #>/<total step #)

Getting Orientation of Mobile Device via Javascript and detecting of device rotation on runtime. In some cases it could be a goal to get change the text of a widget based on the mobile devices orientation. This could be done  via Javascript and css. Follwong possible solutions:  In CSS. More details here https://developer.mozilla.org/en-US/docs/Web/CSS/@media/orientation In Javascript with various method: Here is some documentation : https://developer.mozilla.org/en-US/docs/Web/API/Screen/orientation   As we can read, it is not supported in Safari web browser for iOS.   In a new Project, in 2D canevas, I have added one Button and one Label named label-Result. In home.js, we can create this function very similar to the one provided in documentation above.   $scope.screenOrientation = function() { var orientation = screen.msOrientation || (screen.orientation || screen.mozOrientation || {}).type; if (orientation === "land

How to define Widget at runtime time and what is possible?  For example, the following problem: required is a button e.g. 'button-1' - widget to start a sequence. Now user want to create an 3D-Label that becomes visible after click the 'button-1' and  now for each sequence and step a the 3D-Label have to be visible as long as the sequence is played. The 3d label should display an information for the specific step and also should to have specific position. Unfortunately, it is not possible (using the supported functionality) to create widget on the fly - means create a new feature on run time where the widget was not defined in the design time. Theoretical with some more intensive work – it will be possible – we simple need to check what the UI is doing when you copy and paste widget  (but it is not easy ☹-  and it is not sure if this solution will be stable(if you will be able to implement 1:1 UI) and if it will work in later version -because PTC dev te

Sometimes it is required and will be nice to use a picker functionality. For example, some data picker – so the question: How to achieve this. Yes it is possible in JavaScript that we can incorporate a data/calendar picker into the Vuforia Studio environment? In the Web there are some open source libraries and at least it works 1:1 in preview mode. But mostly they work also fine on mobile devices. In this article a data picker was tested and it was working fine in Preview mode but also was working fine on IOS and on Android devices  The example here is based on the follow link:  https://www.cssscript.com/tag/date-picker/ there are some data picker implemented. Here in this example the library (data-picker) is copied to  the Studio Project download folder and it javascript code will   load the lib and defined a function which is called from button First step is to define a function which enables to load javascript and css from a file / project folder:

How to associate my image texture UV on my 3D Model Here the suggested   workflow is the following: 1.) we will create the CAD data in any CAD tools /   Creo Parametric or any AutoDesk , Catia, Solidwors and etc. / In generally when we prepare the model for the AR usage and there /in the CAD tool/ we will also assigned the texture to a model, component or particular surfaces. So means  the native CAD data will contain already the texture/'s before we will try to use it in Vuforia Studio 2.) So to use the data in Vuforia Studio we need to import it. The import tool is a part of studio and will convert the geometry . Internal Studio used the optimizer tool (here want to refer to the post: "Optimize PVZ before") So means that the native cad data is converted always to PTC light ware format pvz. According to rcp. setting it will  import also the textures or will not import them. So this is the most used way to use textures in Vuforia Studio.  Also

How to create a custom button pressable on HoloLens device? We can create a customer button/button panel on HoloLens performing the following steps: Create a model with button and panel / it could be a panel with more buttons. In this example I used Creo Parametric for the 3d model creation – I estimated for this sample model I needed  30 – 60 Minutes .   The assembly above consist of 3 parts, panel and button. The panel is a part with a pattern of hole feature - in case that we need a circular button. If we need a button with other shape we could use a pattern of cut features     Here in this example I created a button which is circular and has a text which is a cut of the top surface. To have a different button’s I created a family table where a parameter for the text was added. I used the parameter in a relation to change the text in the cut.     Later I added the panel in a new component as default placement and added to each hole

How can ThingWorx (external) data be used to update an experience in real-time?For example, if the data does not fall within a specified range, warning messages will be shown automatically.     In ThingWorx, in Thing, create a Service to check the range and to determine if a warning should be displayed or not. In Vuforia Studio, in the Project, in DATA panel, under External Data section, add the Service. Under Configuration section, check all checkboxes related to refresh to call this Service. Use the ServiceInvokeComplete Event to check the value reported by the Service

ThingWorx properties can be updated from a Vuforia Studio experience.    Below is a simple example: Create a test Thing and a test property for the Thing in ThingWorx :   Create a service for the Thing with text input parameter(Test) and add the below code to update the TestProperty value:   Click Done and Save the Thing In Vuforia Studio, Add a Text Input widget and a Button widget in 2D canvas Add the service of the Thing in the External data Panel Now, bind the Text property of the ‘Text Input’ widget to the Test Parameter of the service as shown below:   Bind the Click event of the Button widget to the Service to update the value of Thing property in ThingWorx   Test the experience by clicking Preview. Enter text in the Text Input widget and click the button.
