Hi @vivekse ,
I tested again the project if it works and now I exported it "HoloLensTest3dButton-article.zip".
I think I forgot the attach the project it self. I am sorry. I attached the 3d Data and 3d Creo Parametric tool- so someone who has Creo Parametric 6.0 to customize the geometry - having button with customer text
This was a mistake I attached the Creo files 2 times and forgot to attach the project itself. I will correct the post :https://community.ptc.com/t5/Vuforia-Studio-and-Chalk-Tech/How-to-create-a-custom-button-pressable-o...
I am sorry for the incontinence. Please, let me know if you can load this project.
Because there is an issue to upload the project I zipped it (the zip file was second zip) with password : PTC
First unzip the project-example.zip to HoloLensTest3dButton-article.zip which should be a valid project and could be imported into Studio
