To Merge Material Definitions in a 2D Section/Elevation

Use this procedure to merge material definitions when creating a 2D section/elevation.

Sometimes a single object in real-life is modeled with different objects in AutoCAD Architecture 2025 toolset. An example is concrete foundations, which are modeled from slabs and walls. These objects should appear as one foundation object in sections and elevations. The new option to merge common material definitions facilitates this result. When a 2D section/elevation is created, all objects of that material definition are combined into a single object. Edges between coplanar faces are removed.
