I import a STL file as my custom 3D model to PC app. But it's become too large when I try to use it in Hololens app.
It about 15mm long when I measure it on CAD. But it become bigger than a 3m long table then I try to place it to the step, that I must pinch the Scale Hologram control two or three times to see the whole hologram.
I check the file from the Guides model-driven app. It's seems that Guides has automatically conversion the STL file to a GLB file. I download the GLB file form Guides model-driven app. And find the scale of model on GLB file is difference from in STL file (about 40 times bigger?).
I guess there may be some problem on conversion, but I don’t know how to solve it. And it will be nice if it can be solved without use other software that need extra license like Unity.
