> Video presenting new features in Allplan 2021 – roof surface

If you want to remove an outline from a roof surface that consists of multiple outlines, you can use the Delete Outline of Roof Surface tool. You can find this tool on the toolbar of direct object modification. Select the roof outline that you want to delete and point to an edge of the outline. By clicking the Delete Outline of Roof Surface tool, you delete this outline; the other outlines do not change. Select the Esc key to close the tool.
If the roof surface consists of only one outline, the Delete Outline of Roof Surface tool is not available. To delete this roof surface, use the Delete tool (shortcut menu of the roof surface or Edit task area).
