I have been using the free web app intermittently for several years now and have encountered this error with some other people’s models on 3d warehouse, but never my own. I made a sketch in SketchUp and then uploaded it to Trimble 3d Warehouse. I then tried to download that collada file to my pc. I continually get the error that the compressed file is invalid.
I have tried all of the following without positive results:
Cleared the cache, cookies, and history (also previous downloads on my pc)
Copied my model and pasted into a new file and tried again
Tried in different browsers and in incognito mode
Made a simple box and had the same results
Support is for paying customers and I feel this is likely a program error as this is not happening with just one model and it is happening with something as simple as a box. However, I am seeking further advice here in case anyone has any other suggestions at all.
I tried one of my own models on my work Mac and PC. There is a difference, in that on Mac you’re immediately given a model folder, inside which is the DAE and the materials folder. On Windows I was given a zip file. In my case the zip file extracted without any problems, and the DAE imported ok, like it had done on Mac.
You could try 7-zip to open the zip file, and see if that shows any error messages.
I am using a windows pc. The files always download as a zip and I extract the contents. When I download the file and try to open the download I get the error.
When I downloaded it from the 3D Warehouse link you provided.
@colin, I uploaded one of my own files to the #DWH and get the same message when I try to open the downloaded Zip file. 7-zip won’t open the files either.
I think this file has a problem colin. Because on mac it downloads as a zip file, not a DAE. and if you rename the zip into dae, bam, you get your collada file.
could be a problem during the conversion ?
@ange.keith.s try changing its name from .zip to .dae
works on mac, might work on pc too
I see the errors in the file in the warehouse. Interestingly it also failed to make a USD version.
Thinking about it, the problem may be because the model only uses colors, and not textures. In doing that the file then because a zip of a single document, and so remains .dae, but gets named as .zip, because there was only one file in the archive.
I have uploaded two versions of the model, one with only colors, one with a single texture in it as well. That should show whether my idea is what the problem is.
That’s weird. I see that other files I’ve uploaded to the 3D Warehouse also fail as Collada zip files if they have no materials applied. Obviously it doesn’t matter in my case but I wonder why the requirement for textures at all.
My guess is that the function that zips up the needed files is failing if there is only one file. When there are textures then there is a .dae and a folder, and the zip gets made ok. If there is no textures folder, the one and only .dae file doesn’t get compressed, but is renamed to be .zip.
