MEP elements, imported “intelligently” (if the IFC model contains specific MEP properties) from a MEP application via IFC file import, automatically translate into native GRAPHISOFT MEP Modeler elements. This enables GRAPHISOFT MEP Modeler users to utilize the full functionality of the application on the received 3D MEP elements, including Collision Detection. This function identifies places in the project where MEP elements intersect with each other and with other elements of the building model. Collision Detection is available in the Floor Plan and 3D windows for all MEP elements, except for elements on hidden layers.
ARCHICAD Building Materials can be defined according to whether they should participate in Collision Detection (using a checkbox in the Categories and Properties panel of Building Materials). This way, only element parts having real geometry will participate in Collision Detection in MEP Modeler. As a result, an MEP element (e.g. duct) that runs through a Building Material used as an air gap will not be considered as collision.
