BIMObject - Missing MEP Macro – Object Not Displaying in 3D

Josh Verran — Tue, 09 Sep 2025 02:44:38 GMT

I’ve downloaded an object from the BIMobject site.
On rebuild I get the following warning:

Can’t find Macro: MEP_m_ConnectionsMEP_4v3, called at line 47 in the 3D script of file …

I’ve got the MEP Library 28 loaded.
The object is password protected, so I can’t open the script (not that I’m fluent in GDL anyway).

Has anyone come across this before?

What would cause a BIMobject part to call a macro that isn’t in the standard MEP library?

Operating system used: Windows 11

Do you have the 'MEP Library 28' folder loaded (which is actually the old MEP Library 27) or do you have the MEP Library library pack loaded?

Which ever one you have, you might want to try the other.

If I had to guess, I would think you would need the old 27 MEP library.

Thanks Barry, that’s a good suggestion.
I tried both options, but unfortunately I’m getting the same result in each case.

Judging by the name, that could be a macro that is specific to the MEP object (version 3?).

Is the macro supposed to be supplied with the MEP object you have downloaded?

There is a MEP_m_ConnectionsMEP_4 macro in the library pack (not sure about earlier versions).

But it is not called "v3" which makes me think it is an amended macro specific for that object.

Thanks Barry

Really appreciate the assistance.
That makes sense what you have suggested.
I checked the Library Pack as well as Monolithic Library for 27 and 26, all show the same name exlcuding "v3".
