The 3D viewer has always been touchy. Just upload renderings of your work to show it off, and rely on those for visualization.

PNG or JPEG work but no stl or igs. Do i have to close my account and create a new one or it is definitively out. In that case I have to find other visualisation on line. Dont work any more no way to run grabcad. Am i the only one with this problem? really very disappointed... I try with other computers, other brooser ect no way. still like attached image...

We have the same exact problem.
We have uploaded one STEP file and it worked just fine. After reuploading it again after few minutes it is not rendering/viewer of 3D file is not loading this file at all.
I can see that it might be the conversion queue problem, but would it take more than 10 hours to convert STEP files? Is the queue that long or is it some other problem?
EDIT: Problem with conversion/Cloudfront? Even PNG files conversion fails (resizing).

this file aren't visible and many others aren't visible from the new uploaded by other users Three Blade propeller left right
Even the jpg isn't visible!

I am also having this issue so I will just add some info to the topic:
► Date of issue: 2024.12.17 (tested various times through day)
► no STEP files will display in 3D viewer.
► I checked all my settings. good STEP formats.
► my older models previously viewed OK, but now show an error
► the error is "Error reading model data from SCS file"
► Using Google Chrome with adblockplus
► Deactivating adblockplus did not help
► Using Microsoft Edge browser did not help
► images (.jpeg) display fine, native cad (solidworks) does not.
Hope to get more info from this group! I have a lot of models that I use for teaching students.
