Hello, I’m using Blender 3.2. I have a problem importing .dae file to Blender.
It spends around 14 hours to import it. (now, it is importing)
the model’s description said it has
2,591,806 polygons
9Mb file size
I wonder why it spend so much time like this.
here is the collada file which I downloaded

here is a screenshot which I use to check if it is processing.
if it has a lot of individual objects, it can take a very very long time
To add to this, it looks like you’re bottlenecking on RAM. Anything higher than 75% RAM usage and everything on your computer will slow to a snail’s crawl.
It is using assets from all over Trimble as instances there is only a base object in that DAE file …so it is repeatedly trying to find a mesh that does not exist… or has no mesh data
It would be better to save off as GLTF or another file type if you have the access to do so…
I have never found DAE to be reliable as an exporter…
But to save you all the hassle…
It is a Blender 3.1 file… Drop it next to the original texture folder…
Thank you so much, You’re my savior. 
I agree, My laptop is not suit for heavy 3D work.
Good job, kind stranger
