Use the Convert to Solid Part tool to convert a sheet metal part into a solid part. When you convert the part, all sheet metal features are deleted from the part. This operation might be necessary in order to add specific solid features to the part. Alternatively, you can add solid features by suppressing the sheet metal convert feature in the Model Tree, modifying the solid part, and then resuming the suppressed convert feature. To suppress the feature, drag the green bar at the end of the Model Tree items above the convert feature. To resume the feature drag the bar to the end of the Model Tree items.
