What happened to the option to create a pdf using the .u3d file type?

[ryanh71843333]

I used to be able to create a 3d pdf by following this work flow.

File - Create - pdf from file - then select a .u3d file and click open

a new 3d pdf would be created.

As of a couple days ago it stopped working.  Looks like all the 3D file types have disappeared as supported file types.  I used to be able to use step files as well but that is go to.  Anyone know what is going on??

Windows 10Pro

no changes made recently

Ran the repair installation and checked for updates.  I am all up to date.

Still can not create a pdf from a .U3D file.  Adobe says that the .U3d file is a supported direct file conversion.  But that seems to have gone away.

Supported file formats in Acrobat and Reader

I will go out on a limb and say that Adobe has removed this option as a direct file conversion.

I do have the exact same problem. I happened to convert a lot files lately so i can say for sure that the problem occurred between the 16th or 17th as I still could use the option on the 15th but not the 17th anymore.

Will you let me know if you find out what is going on?  I think Adobe is obsoleting the .u3d file conversion.  A work around I have been using is to create a blank pdf and adding Rich media.  It works but is cumbersome.

I have exactly the same issue. The last time it worked for me was on 14th May.

    I tried this method but could not find the featurestate file to modify. any suggestions an what is going on?

[Steve Cordero]

Both the "FeatureState" key and the "Block3DConversion" DWORD value need to be created manually by you.

Hello Steve,

I found this answer very helpful for WINDOWS users, but is there a similar solution for MAC OS users?

... Just found that U3d files can be exported via (free) "Meshlab" (at least Version 2023) and "DazStudio" ... i have been looking for this free-convert-option for a long time, hope it helps!
