To Regenerate an AutoCAD MEP 2022 Toolset Model

Use this procedure to regenerate an AutoCAD MEP 2022 toolset model. You should regenerate a drawing model after making a large number of changes to the model, after applying new display representations to objects in the model, or if you are working with external reference (xref) files. Regenerating an AutoCAD MEP 2022 toolset model steps through its objects and displays them based on current settings and preferences. You should also regenerate the model when objects do not display correctly, specifically after an AutoCAD Regen. However, to avoid performance problems during regeneration of large drawings, select only those objects that are displaying incorrectly.

1. Click View tab Appearance panel Regenerate drop-down Regenerate Model .
2. Select one or more objects to regenerate, or press Enter to regenerate the entire drawing.
