The GRAPHISOFT MEP Modeler for ARCHICAD 21 is an Add-On developed for the ARCHICAD user interface: architectural and engineering firms can model and edit 3D MEP (mechanical, electrical and plumbing) systems and networks (ductwork, pipework, cable trays) and coordinate them in ARCHICAD BIM models by using ARCHICAD tools and interface.
MEP Modeler is also compatible with IFC.
Note: The MEP Modeler package includes a separate facility for direct AutoCAD MEP export. (This is an AutoCAD plug-in, for PC’s only, and can be installed from the MEP Modeler CD. See the ARCHICAD Connection PDF document for details on how it works; this document is available from the Help menu of the AutoCAD plug-in’s dictionary editor.)
You can create the MEP model within ARCHICAD, based on 2D documentation received from engineers. ARCHICAD’s built-in Collision Detection function (Design > Collision Detection) lets you check collisions between any two element categories - for example, between structural building elements and
•the MEP elements you defined with the MEP Modeler, and/or
•the MEP elements imported from a mechanical consultant's IFC model.
MEP Elements are GDL Objects, with parameters and settings similar to object-type elements in ARCHICAD. MEP Elements work just like regular ARCHICAD library parts, but also have additional, MEP-specific parameters.
MEP Modeler comes with an extensive MEP Library of specially configured MEP Elements. If you are using the MEP Template provided with the Add-on, this library is loaded automatically.

Common types of MEP Elements include:
•a Straight segment, such as a duct with identical geometry at either end. Examples: Duct tool, Pipe tool and Cable Carrier tool.
•a Bend. Some Bends are inserted automatically during Routing, or as a result of editing MEP elements, if two otherwise unconnectable elements require that a bend be inserted.
•a Transition. This is a straight segment whose geometries at its two ends are unequal. Transitions are used to connect two MEP elements of different width/height/shape.
•a Junction. These include a Tee junction, a Wye junction, and a Take-off.
•a Terminal - for example, a ceiling diffuser or a grille or a sprinkler placed at the end of a pipe or duct. A Terminal has only one connection port.
•Inline element, such as a valve or filter, placed inside the route. Inline elements are straight segments open at both ends.
•Equipment - such as a furnace, with one or more connection ports. A single Equipment element generally is generally assigned to multiple MEP Systems (e.g. Heating, Exhaust Air), and are connected to multiple (Pipework, Ductwork) MEP element types.
There are two ways to place MEP Elements:
•Use the MEP Tools to place individual MEP Elements.
•Use the Routing function to place multiple connected MEP Elements with a series of clicks.
