How do I edit MEP elements in ARCHICAD without the add-on loaded?

If a project created in an MEP environment (add-on, MEP license and MEP Library loaded ) is reopened using ARCHICAD only (without MEP Modeler but with the MEP Library loaded), the MEP objects are available, although locked for editing. If you wish to edit or move these elements, you must first unlock them individually (Edit > Locking > Unlock). Their MEP connection information is lost once you have edited them in a non-MEP Modeler environment and they behave as plain GDL objects in ARCHICAD.

How do I convert standard ARCHICAD elements into MEP elements?

If an ARCHICAD project is opened (using File > Open) in an MEP Modeler environment, then the GDL objects that are MEP-compatible will be automatically “smartened up” to include MEP Custom Settings and connection parameters. Their connection parameters can be used to include these objects as part of an MEP route. Adjacent MEP objects with connected hotspots are automatically connected (provided that the connection geometries are compatible).

There are some objects in the MEP environment without connection parameters – how do I convert these?

It could be that some elements in a teamwork file, or elements pasted into a file with the MEP add-on from a file without the add-on loaded, will not be automatically converted. These can be converted using the “convert objects to MEP elements” button in the MEP Preferences. MEP Preferences is available at Design > MEP Modeling > MEP Preferences.

How do you control an MEP license on an ARCHICAD network key?

There is an option in the MEP Preferences that will control whether MEP will be enabled. Check the option to reserve an MEP license automatically to start MEP Modeler whenever ARCHICAD is opened, providing a licence is available. This option is turned off by default.

MEP Preferences 3

If the option is not checked, MEP will not be enabled when ARCHICAD is started, even if a licence is available. MEP related commands are active (with the exception of MEP Pet Palette items) for the user even if no MEP license has been reserved. If an MEP related command is used, the license will be automatically reserved if possible and work can be continued. If the license reservation is not successful, the command will not be executed.

If ARCHICAD is started without MEP, a licence can be reserved manually in the Licence Information dialog.

How do I update MEP Modeler?

The MEP add-on is part of the standard ARCHICAD package however to activate it you need to run its installer that you can download from GRAPHISOFT’s download page.  MEP Modeler add-on will be updated by ARCHICAD Updates. Therefore the build numbers of MEP Modeler and ARCHICAD are the same. If MEP Modeler is installed later than the installation of the latest ARCHICAD update, MEP is automatically updated to the build number of ARCHICAD. You can check the build number of MEP Modeler in the Add-On Manager.

I have removed the MEP add-on – why do I now get an error message?

The MEP add-on is part of the basic installation and ARCHICAD will not start without it. If MEP is no longer required on a computer, it should be uninstalled from the Control Panel, or by running uninstaller.exe in the Graphisoft\ARCHICAD #\Uninstall.MEP folder. If MEP is unistalled in the recommended way, no error message appears when launching ARCHICAD. (The MEP Modeler is part of the basic installation of ARCHICAD. This means that installing MEP Modeler makes the MEP Template, the MEP Work Environment profile and the MEP Library available for ARCHICAD. When uninstalling, the add-on stays in the add-ons folder, thus ARCHICAD can still be launched, but the template, the Work Environment Profile and the Library will be removed. If you remove the whole MEP Modeler folder from the Add-Ons folder, the connection between ARCHICAD and its add-on will be broken, that’s why ARCHICAD will not start.)

Where are the plumbing fixture objects from the object library?

If you are using MEP Modeler, the MEP specific library parts are accessible through the dedicated MEP Tools grouped under Ductwork, Pipework and Cabling.

If MEP Modeler is uninstalled, but the MEP Library is still loaded, the same library parts are accessible through the Object Tool.
