Some Components do not link to correct 3D packages (aka. managed library doesn't update/link with board, Part II)

[Dan.K.2020]

Hi there,

in that thread, a user discussed the issue of having a mix of parts from the same library, in both the unmanaged and the managed version of that library.

Now I have a similar issue with a single managed library. The components are linked to devices in a managed library, the managed library contains 3D packages for these devices, however, the STEP file does not reflect this. 

For example this component does not have a proper 3D representation in the STEP file. It's a flat rectangle when imported into a CAD software. As you can see in the screenshot, right clicking this component (in Eagle) does not show the menu entry "edit 3d package":existing component on the board

This is strange as an 3D package has been assigned to the device. That can be seen when clicking "open device" (or "Device öffnen").

When I add this device from the library to the board again, a component with 3D package is used and the STEP file shows the 3D. package.  As you can see in the screenshot, right clicking this component (in Eagle) does show the menu entry "edit 3d package":Component with 3D package

Obviously, the component/device links to a managed library but some do not use the 3D package that has been assigned to the device.

Why is this and how do I fix this? 

There should be an easier fix than to manually replace each device as decsribed in the thread linked in the beginning of this posting. Clicking "update library" did not help.
