I am extremely new to Web Development. I'm trying to create a configurator application that can load a part into the viewer, have a menu to modify its dimensions, and update the viewer. So far, I developed a basic Web Application that can create a bucket, upload a file, translate it, and load it into the viewer following this tutorial: https://forge.autodesk.com/developer/learn/viewer-app/overview
Now, I would like to request custom dimensions from the user and update the file with those dimensions. I'm not sure how I can get started with this as I have very little knowledge on the subject. This is the link I found for modifying models: https://learnforge.autodesk.io/#/tutorials/modifymodels
What would be the basic steps to incorporate the modify models code to this? Also, would I need to download AutoCAD/ Inventor/ Revit/ 3ds max to run or test this code? I'm feeling lost and am not sure where to go from here. Any help would be greatly appreciated.
