Resources
Use the Resources tab to add different resources such as CAD files, image files, audio files, etc:
Click the plus sign next to Resources to add one or multiple resources.
You can select multiple files using the Control key and selecting files in the file browser window.
When adding CAD files to your Experience, you can also select whether or not you want to run the CAD Optimizer. The CAD Optimizer does the following:
Allows you to choose from three automatically generated derivatives of the source data that vary in fidelity and size
Removes IP and strips out accurate CAD B-REP geometry
Shrinks the data which speeds up delivery and improves interaction
Makes your real-world CAD data work in AR with no remodeling
Once you have selected the files, click Add.
