Often, we need to display some sections, or we required to have a view of a x-section of the model. This is in generally no part of the current functionality but there are some approaches which could be helpful. In this article I want to mention 3 different approaches, which could be used but no one of them is really perfect:   1.) uploading different models -  so we can use an additional models for each cut and then we can change the model if you want to display a cut, it means you can make the one model not visible and the display the second model or vice versa.  I tested with cuts created in Creo Illustrate 5.0 and Creo View 5.0 but it seems that Vuforia Studio could not display them /neither as part of sequence or as static to the current figure:     The only possible  way in this example is to create in Creo an assembly cut /with option cut also on part level  and  then create from there a new .pvz model.  In this case this seems to work fine: :     2.) the second approach is to remove components  step  by step,  so to see the inner components when the outer components are blanked: All different components, which should be displayed or blanked, need to be defined as modelItem where we can set the visible property to true or false Is also possible to blank or display  a list of components where the list is defined in json file. This could be done with JavaScript code. In this case we do not need to define a modelItem widgets.  For more information you can check the post     3.)  The last most powerful option is to use a shader for the model Widget. So for example we can use some kind of clipping functionality of the model where we can set the x min and x max value or ymin and ymax or zmin and zmax value what should be displayed. This will create a clipping effect. So only the geometry which satisfy this criteria will be displayed.     How to achieve a clipping functionality using a shader. 3.1) define a shader - this requires creating a tmlText widget where we can define the shader Code. The code should be inserted into the text property of the tml widget For the clipping along x axis with planes which are parallel to the  YZ plain we need to define the following javascript with GLSL:   <script name="slice_world_based_x" type="x-shader/x-vertex"> attribute vec3 vertexPosition; attribute vec3 vertexNormal; varying vec3 N; varying vec4 vertexCoord; uniform mat4 modelMatrix; uniform mat4 modelViewProjectionMatrix; void main() { vec4 vp = vec4(vertexPosition, 1.0); gl_Position = modelViewProjectionMatrix * vp; vertexCoord = modelMatrix*vp; // the surface normal vector N = vec3(normalize(modelMatrix* vec4(vertexNormal,0.0))); } </script> <script name="slice_world_based_x" type="x-shader/x-fragment"> // this setting is needed for a certain use of properties precision mediump float; // determine varying parameters varying vec3 N; varying vec4 vertexCoord; // determine shader input parameters uniform vec4 surfaceColor; uniform float slicex; uniform float slicewidth; const vec3 lightPos = vec3(1.0, 2.2, 0.5); const vec4 ambientColor = vec4(0.3, 0.3, 0.3, 1.0); void main() { // calc the dot product and clamp based on light position // 0 -> 1 rather than -1 -> 1 // ensure everything is normalized vec3 lightDir = -(normalize(lightPos)); vec3 NN = normalize(N); // calculate the dot product of the light to the vertex normal float dProd = max(0.0, dot(NN, -lightDir)); // calculate current color of vertex, unless it is being clipped... // only geometry with coordinates which satisfy the condition below // will be displayed if ( vertexCoord.x > (slicex + slicewidth/2.0) || vertexCoord.x < (slicex - slicewidth/2.0) ) { discard; } else { // calculate the color based on light-source and shadows on model gl_FragColor = (ambientColor + vec4(dProd)) * surfaceColor; } } </script> Save the tml Text widget .     3.2) You can also define shaders for clipping along the Y and the Z axis. Here you can use the same shader javascript definition but you need to change the shader name and to modify the if  check respectively to the Y or Z coordinate:   <script name="slice_world_based_y" type="x-shader/x-vertex"> ... // calculate current color of vertex, unless it is being clipped... if ( vertexCoord.y > (slicex + slicewidth/2.0) || vertexCoord.y < (slicex - slicewidth/2.0) ) { discard; } else ...   To set the clipping values for different axes and to control it by   sliders we can use some code like this:   $scope.DIR="y"; $scope.slice = function() { var slicexCur = ($scope.view.wdg['slider-1']['value']/100.0)-0.5; var slicewidthCur = ($scope.view.wdg['slider-2']['value']/100.0); $scope.view.wdg['modelx']['shader'] = "slice_world_based_"+$scope.DIR+";slicex f "+ slicexCur + ";slicewidth f " + slicewidthCur; } //////////////////////////////////////////// $scope.$on('$ionicView.afterEnter', function(){ // Anything you can think of $scope.clickY() }); /////////////////////////////////////// $scope.clickX=function() { $scope.view.wdg['toggle-X']['value'] =true $scope.view.wdg['toggle-Y']['value'] =false $scope.view.wdg['toggle-Z']['value'] =false $scope.DIR="x" } $scope.clickY=function() { $scope.view.wdg['toggle-X']['value'] =false $scope.view.wdg['toggle-Y']['value'] =true $scope.view.wdg['toggle-Z']['value'] =false $scope.DIR="y" } $scope.clickZ=function() { $scope.view.wdg['toggle-X']['value'] =false $scope.view.wdg['toggle-Y']['value'] =false $scope.view.wdg['toggle-Z']['value'] =true $scope.DIR="z" } ///////////////////////////////////////   Here the slice() function is called in the slider change event (for the both slider widgets). For better understanding of the functionality you can review the attached Vuforia Studio project Here attached the improved version for HL. It is also approved by dev team.  slice_example.zip https://community.ptc.com/sejnu66972/attachments/sejnu66972/tkb_vuforiatechtips/48/4/slice_example.z... Another version (also for HL) attached here is the example   slice_example_using_ABCD  project – where the dev team demonstrates an efficient way showing how we can define a cutting plane via plane ABCD parameters (refer to  plane geometry equations : geometry https://en.wikipedia.org/wiki/Plane_(geometry)   To cover this functionality the dev team developed some studio extensions that  PTC customers can use instead.   That extensions widgets will handle reflections etc, and I it is recommend to use  those extensions .: https://github.com/steveghee/OCTO_Studio_extensions https://github.com/steveghee/OCTO_effects_extensions

With release 9.1.0, Vuforia Studio now supports Area Targets. Area Targets can be used when creating spatial instructions using the surroundings as interactive elements to be explored. For example, you can use an Area Target when you want to deliver augmentations to stationary objects in a scanned environment. You'll need to create an Area Target before you can import it into Vuforia Studio to leverage the Area Target widget. Below is an overview of the required steps to create and upload Area Targets for Vuforia Studio.   Step 1: Create a Vuforia Engine Developer Account   This account is separate from your regular PTC support account and is required to generate Area Targets.   Step 2: Download a Target Generator Once you've created a Developer account, you'll need to download a target generator. The target generator you download will depend on the device used to scan your environment.   Vuforia Studio currently supports scans created with: Matterport Pro2 Camera Requires the Area Target Generator desktop application, available for Windows and Mac. iOS devices with LiDAR sensors Requires the iOS app Vuforia Area Target Creator to scan and create Area Targets Step 3: Create an Area Target   Creating an Area Target using the Matterport Pro2 Camera:   Log into the Vuforia Area Target Generator with your Vuforia Developer Credentials Select New Area Target from Matterport Scan Enter your Matterport token information See Retrieving Models with the Matterport™ API Token for instructions on obtaining your token ID Enter the Scanned Space ID and Area Target Name The Scanned Space field is the Matterport™ SpaceID and a unique 11-digit ID that is associated with your individual scans. Find the unique ID of your scan by opening the scanned space from your Matterport™ account. Copy the entire URL, or just the SpaceID portion as illustrated and paste it into the Scanned Space  field. Area Target name must not contain any spaces Select Create Area Target to generate an Area Target of your scan. Full instructions for creating a scan and area target using the Matterport Pro2 Camera can be found here.   Creating an Area Target using the Vuforia Area Target Creator (requires internet connection): Login with your Vuforia Developer Credentials from step 1. Select the Plus Button to create a new scan and enter a scan name Start the scan Press the Stop Button to finish the scan Select Generate to generate an Area Target database   Step 4: Prepare your files for Studio   NOTE: All filenames are case sensitive   Area Targets created with the Vuforia Area Target Generator: Navigate to the location you entered when creating your Area Target Location defaults to C:/Users/<username>/Documents/Vuforia Areas Create a zip file titled <target_name>.zip that contains ONLY: <target_name>.dat <target_name>.xml <target_name>_authoring.glb Area Targets created with the Vuforia Area Target Creator: Share your files to your Studio authoring machine Press the Container button and swipe one of the Area Target datasets listed to the left. A share icon will appear. Press the Share icon next to a listed dataset Select your transfer method It is possible to manually pull the files directly from your device. Using iTunes or a similar file explorer, navigate to the app's AreaTargetData folder and copy the desired Area Target directory.  Ensure that your <target_name>.zip file contains ONLY: <target_name>.dat <target_name>.xml <target_name>_authoring.glb Step 5: Upload your Area Target file to Vuforia Studio Add an Area Target widget your canvas Select the green plus button next to Data set  Browse to the location of your <target_name>.zip file and select open   See our Help Center for more information on Area Targets in Vuforia Studio.

Vuforia Studio New widgets for 3D Eyewear projects: 3D Press Button We recommend using a   3D Press Button   in place of the   3D Button , as the   3D Button   widget will be deprecated in a future release. A few things to keep in mind: In May, the   3D Button   widget will no longer available for new projects. This will not immediately affect existing projects that contain   3D Button   widgets, and you will still be able to edit and re-publish projects that contain them. In the future (TBD)  all existing  3D Buttons  will be transitioned to  3D Press Buttons . More information on this transition will be forthcoming. 3D Image Button 3D Toggle Button 3D Checkbox 3D Panel Ability to pin and unpin 3D Audio and 3D Video widgets in runtime German and Simplified Chinese now fully supported for HoloLens 2 voice commands If your HoloLens was set to English when you installed Vuforia View, you'll need to delete it and reinstall after you've changed your language setting to Simplified Chinese or German Bug fixes and minor improvements Vuforia View Bug fixes and minor improvements Experience Service Support for PostgreSQL 11.6 and 12.4 Bug fixes and minor improvements

In Vuforia Studio version 8.5.13 a new metadata is intruduced. This will make the techniques described e.g. in the posts "How to extract the components with properties from a pvz file","Extracting the viewables and the seqnece steps information from a .pvz file for the usage in TWX" and "How to extract model data of 3d models in Vuforia Studio (without external Tools)?"  for the most cases not neccessarly any more. as In Vuforia Studio when a model is imported (add Resource) there is a new check button “Allow the Experience access to CAD metadata” :   The selection of this checkbox lead that when the model is loaded to the “app/resources/Uploaded” folder but also an a json object with the name <model name>.metadata.json Example when we load the model “Coffee Maker Model_High.pvz” then we have also a json file named “Coffee Maker Model_High.metadata.json”. This JSON file contains the metadata to the coffee maker model   The metadata json file contains some different sections for each component / For each component / CompPath Id  we have a sub object – comp obj {"/":{"":{"Adapter_name":"proepview",… "/11":{"":{"Feature_Id":"11","Source_file_name": … "/14":{"":{"Feature_Id":"14","Source_file_name": … Where “/” means the root asm , “/11” and “/14” are components paths The component object contains the following sections : general(empty string as key of the json obj) “”, "PROE Parameters" and "__PV_SystemProperties" (see the attached example “Coffee Maker Model_High.metadata.json”) The one possible approach could be , to use only this json object directly  but we can use also the PTC API which is provided starting with the Vuforia Studio 8.5.13 Metadata Access: Read the json object into memory (javascript):  In this case we can use the json object which was already created when the model data is omported in Studio.         var metaDataArray=[]; //////////////////////////////////////////////////////// //========================== When Model Loaded Event $rootScope.$on("modelLoaded", function() { if (arguments.length >0){ //================== if args >1 ====================== var modelWidgetId=arguments[1]; metaDataArray[modelWidgetId]={}; console.warn($scope.view.wdg); let wdg= $scope.view.wdg[modelWidgetId]; let mdlsrc=$scope.getWidgetProp(modelWidgetId,'src'); console.log( "mdlsrc="+mdlSrc); //==== extracts the model file name with extension let mdlNameExt= mdlSrc.replace(/^.*[\\\/]/, ''); console.log( "mdlNameExt="+mdlNameExt); //==== extracts the model file name without extension var mdlName=mdlNameExt.replace(/\.[^/.]+$/, ""); console.log( "mdlName="+mdlName); // ---adds the modelname to the array element for the widget metaDataArray[modelWidgetId]['mdlName']=mdlName; metaDataArray[modelWidgetId]['CompIdList']=[]; // $https call of the JSON file form the UPLOAD folder $http.get('app/resources/Uploaded/' + metaDataArray[modelWidgetId]['mdlName']+'.metadata.json') .success(function(data, status, headers, config) {//-------- success fnc metaDataArray[modelWidgetId]['data']=data; angular.forEach(data , function(value ,key){ //-------- ForEach json loop metaDataArray[modelWidgetId]['CompIdList'].push(key); });//--------end of ForEach json loop // print the data to the console console.log("metaDataArray[]"); console.warn(metaDataArray); })//-------- end success fnic .error(function(data, status, headers, config) {console.log("problem in the http will create a new ");}); //////////////////////////////////////////////////////// })          The code listed above will load the json file to the modelWidget/s (it will works also if we have many model widngets there - and each model widget ponts to model which is imported with metadata) When we  test this code we can check the object in memory (console.warn() ) :   Now we can access the metadata using the normal JSON functionality - so we can   access the component data via the Comp Path Id / id paths - corresponds to the modelItem widget property occurrence:         $scope.app.testFunction= function() { // visiting array with string index Object.keys(metaDataArray).forEach(function(key){ console.log(" model Widget = "+ key); let compList = metaDataArray[key]['CompIdList']; //select randomly from the coponent list let randomNum= parseInt(Math.random()*metaDataArray[key]['CompIdList'].length) let randomComp= metaDataArray[key]['CompIdList'][randomNum]; console.log("random component selected = " +randomComp); // let DispName = metadata.get(randomComp, 'Display Name') /*** you can use here one of the following fields "Child Count","Component Name","Display Name","Model Extents (mm)","OL File Name","Part Depth""Part ID","Part ID Path","Part Name","Part Path" ****/ let DispName = metaDataArray[key]['data'][randomComp]['__PV_SystemProperties']['Display Name'] console.log("DispName= "+ DispName) let model_extend_mm = metaDataArray[key]['data'][randomComp]['__PV_SystemProperties']['Model Extents (mm)'] console.log("model_extend_mm= "+ model_extend_mm) let creaDate = metaDataArray[key]['data'][randomComp]['PROE Parameters']['CREATION_DATE'] console.log("creaDate= "+ creaDate) console.log("model_extend_mm= "+ model_extend_mm) let designState = metaDataArray[key]['data'][randomComp]['PROE Parameters']['DESIGN_STATE'] console.log(" designState= "+ designState) // make a selection string for this component let mdl_selection= key+"-"+randomComp; console.log ("mdl_selection="+mdl_selection) // generate some random rgbá color let r =parseInt(Math.random()*255); let g =parseInt(Math.random()*255); let b =parseInt(Math.random()*255); let a =parseInt(Math.random()*0.8)+0.2; //apply blink funciton for this component selection with random color $scope.blinkSelection(mdl_selection,'rgba('+r+','+g+','+b+','+a+')',200,22); }); }         When we test the listed code above we will have in the chrome console window: Using furhter the json  functionality we can also implement e.g. some user picks where you can associate it with the metadata :         angular.forEach($element.find('twx-dt-model'), function(value, key) { // find all model widget feature and perform funciton() // for each model widget - key == modelWidgetId //define the userpick function for each modelWidgetId angular.element(value).scope().$on('userpick',function(event,target,parent,edata) { if (edata) { if ($scope.currentSelection) { // selection is not null make it undefined tml3dRenderer.setColor($scope.currentSelection, undefined); } //create the selection string <modelWidgetId>-<occurance Path Id> $scope.currentSelection = target + '-' + JSON.parse(edata).occurrence; //generate a random rgba color let r =parseInt(Math.random()*255); let g =parseInt(Math.random()*255); let b =parseInt(Math.random()*255); let a =parseInt(Math.random()*0.8)+0.2; //call blinkSelection function for the selected component $scope.blinkSelection($scope.currentSelection,'rgba('+r+','+g+','+b+','+a+')',200,10); //write the data SystemProperty of this compoonent in to a textArea Widget $scope.setWidgetProp('textArea-1','text',JSON.stringify( metaDataArray[target]['data'][JSON.parse(edata).occurrence]['__PV_SystemProperties'])); } }) })           This code will write the meta data to the selected component form the __PV_SystemPoperties section to a text area widget. Also the component will blink fwith random rgba color: I attached an small example (modelMetaDataMobilTest.zip) which should demonstrated the described techniques   Vuforia Studio metadata API The first step is to call the metadata for a model widget. For this we can use the following construct e.g. WidgetId is ‘model-1’ :       PTC.Metadata.fromId('model-1').then( (metadata) => { // <HERE CALL YOUR CODE with metadata > });       So for example we can use get the “Display Name of the component with the path Id =’/0/6’:       PTC.Metadata.fromId('model-1').then( (metadata) => { Let disp_name= metadata.get('/0/6', 'Display Name'); console.log(“Display Name=”+disp_name); });       The most of the  methods which could be applied to the metadata object and also some examples are described in the PTC Help (Incorporate CAD Metadata Into an Experience) This functionality is available first with Vuforia Studio 8.5.13. To this article is also attached a PDF copy of the metioned link above. There we can use 2 different approaches: To get a selected object or list of objects: let metaDATA=PTC.Metadata.fromId('model-1') metaDATA.then(function(meta) { console.log("success func of metaData"); //a test with a fix model widget id var designer = meta.get('/11','DESIGNER','PROE Parameters'); console.log("Designer= " + designer); var ptc_mat = meta.get('/11','PTC_MATERIAL_NAME','PROE Parameters'); console.log("PTC_MATERIAL_NAME= " + ptc_mat); var dispName = meta.get('/11','Display Name','__PV_SystemProperties'); console.log("dispName= " + dispName); var DV_System_Categ= meta.get('/11'). getCategory ('__PV_SystemProperties') console.log(JSON.stringify(DV_System_Categ)) let myQuery=meta.find('Display Name').like('PRT').find('Part Depth').in(0,3); console.log("myQuery Name:"+myQuery._friendlyName); console.log("myQuery selected Paths :"+JSON.stringify(myQuery._selectedPaths)); }) .catch(function(err) {console.log("problem with the read of metadata ");console.warn(err);}); ​ To call for the selected object a callback function where the Path id was passed as function argument:       $scope.app.testCustomSel= function(){ let pathDepth=4 $scope.app.testCustomSelection('model-2', $scope.app.whereFunc,$scope.app.selectFunc,pathDepth) $scope.app.testFind1_modelId='model-1' PTC.Metadata.fromId( $scope.app.testFind1_modelId) .then(function(meta) {meta.find('Part Depth').lessThan(3).find('Display Name') .like('PRT',$scope.app.selectFunc);}) } //========================== app.testCustomSelection $scope.app.testCustomSelection= function(modelId,whereFunc,selectFunc,pathDepth) { BPRN("app.testCustomSelection()"); $scope.app.testCustomSelection.modelId=modelId; $scope.app.testCustomSelection.pathDepth=pathDepth var metaDATA= PTC.Metadata.fromId(modelId) .then(function(meta) {meta.findCustom(whereFunc,selectFunc);}) } //------------------------------------------------- $scope.app.whereFunc = function(idpath) { // scope var `this` is the metadata instance const depth = this.get(idpath, 'Part Depth') const name = this.get(idpath, 'Display Name') return parseFloat(depth) > $scope.app.testCustomSelection.pathDepth || (name && name.search('PRT') >= 0) } //------------------------------------------------- $scope.app.selectFunc = function(idpath) { const name = this.get(idpath, 'Display Name') console.log("app.selectFunc["+$scope.app.testCustomSelection.modelId+"] idpath=" +idpath+ " >>>Name: "+name); return this.get(idpath, 'Display Name');}         In the example above the query is done by the  where function and for all selected models the callback function select Func  is called where the pathId was passed to the function   I attached an small example ( modelMetaDataMobilAPItest .zip) which should demonstrated the described techniques
