2D Symbol Issues with Library Part Maker Objects since updating to 28.3.3

Jeff Galbraith — Wed, 27 May 2026 19:13:44 GMT

2D Symbols for library parts are no longer working. Objects I create now in LPM or copy from other projects no longer have visible 2D symbols. Now when I select the black dot and open settings the symbol preview pane says 'Invalid 2D Symbol. Open the library part for editing and check it's 2D script or errors.'

The only thing I can think of that might have caused this was updating to version 28.3.3. Has anyone else seen this? Is this resolved in the most current update?

Does anyone know what to look for in the 2D symbol GDL code of the object that could be related to this?

Thanks,

Given that you mention the AC28 update, I am assuming they worked in an earlier update of AC28?

For me the same. I created the object at LPM (monolitic lib version 27). The object was fully customized, and saved at our own library. When the migration for the global library, it showed the same message (Invalid 2D Symbol. Check the GDL text...)

Greetings
We had the same problem in AC29
We opened the source file and regenerated them using AC29's LPM. That solved the issue.
