When you export an AutoCAD MEP 2023 toolset drawing to AutoCAD, the annotative objects—like all other objects—are exploded into basic AutoCAD objects that maintain their original layer, color, and linetype.
If you export a drawing with multiple viewports in paper space, the annotative objects are exploded into multiple blocks, one for each viewport, in order to maintain visual fidelity. You can export annotative AutoCAD objects in the same way by selecting Maintain visual fidelity for annotative objects on the Open and Save tab in the Options dialog box.
Beginning with AutoCAD 2009, if you open an exported AutoCAD MEP 2023 toolset drawing in AutoCAD, the AutoCAD MEP 2023 toolset objects that were annotative prior to export will be annotative in AutoCAD.
