Pinch to scale a model with thingmark in Vuforia Studio

Hi @FC_12202090 ,

when you use a thingmark that will fix the world coordinate system on the location where the thingmark is scanned ( when the Thingmark is on x,y,z 0,0,0 with rx,ry,rz 0,0,0) When the thingmark has x,y,z,rx,ry,rz different from zero then it will move the world coordinate system in inverse order. I did not check it but I believe that when you try to move the x,y,z properties of the Thingmak then it will move the model. So gestures like the spatial target , so far I know,  are here not working (when you means that in your question) but you can use  e.g. values and sliders. I think also the scale could be changed. But here is better to change the scale of the model widget. Because when you scan a thingmark the project is adapted to a scale calculated by the ration of the properties  scale thingmark size value to  real word scanned size. Mostly that should be 1:1. Means the size of the Thingmark should corresponds to the real print size of the used thingmark. When it is different that will apply a scale calculated from the ratio of that quotient . Am not sure if it will be a good technique to change the thingmark size dynamically after we scan it and the tracking is started. The recommended technique after scanning the thingmark is to change the ModelWidget scale and the properties - so far I know.
