You can improve project coordination using the interference detection tool. The software checks for interferences between different types of objects, such as between ducts and pipes or between these MEP objects and architectural/structural objects, such as walls. Interference detection can occur on objects within the current drawing, objects in referenced drawings (xrefs), or objects in both the current drawing and in an xref. AutoCAD MEP 2026 toolset shows interferences as mass elements in the drawing. You can add tags to the mass element and insert opening symbols that get captured in a linked interference detection schedule. For more information, see About Finding Interferences.
