# Modify Configurations ## Modify -- Roof surface execution This function allows the roof surface execution of a roof area to be changed. The roof area is selected with the mouse at the centering polygon. A different execution can be selected from the master data, or the existing execution can be changed directly on the roof area. All settings available in the dialog box 'Roof centering -- Roof surface execution' are provided for this purpose. The roof is then re-centered because the changed execution may also alter the appearance of the roof panels. ## Modify -- Line execution This function allows the line execution of a roof area to be changed. After selecting the function, the program asks whether the edge profiles should be preserved. This is relevant if you want to keep the shape of a roof edge but change the name of the existing line execution (for example, for measurement). In that case, answer 'Yes'. If you then assign a different execution to a line, the panels at that roof line retain their offsets, but the line is assigned a different execution. The roof line is selected with the mouse at the centering polygon. A different execution can be selected from the master data, or the existing execution can be changed directly on the roof line. All settings available in the dialog box 'Roof centering -- Line execution' are provided for this purpose. The roof is then re-centered because the changed execution may also alter the appearance of the roof panels. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
