Question

The warning 282449 appears: "Lines No. ... are equal." Do the identical lines have an effect on the calculation? Do I have to delete the identical lines?

Answer

It may happen that surfaces are not connected though they should be. In this respect, double lines may have an effect on the calculation. It is better to clean the model and remove all double lines.

You can quickly find the double lines by using the feature "Tools → Model Check → Overlapping Lines." This tool also allows you to export the line pairs as an Excel list or create partial views (see the highlighted buttons in Figure 02).

However, it is often not easy to delete the lines as they are assigned to different objects. So if you delete one of the lines, you also delete a surface, for example. Therefore, you should first check for all structural components whether the lines can be deleted, and change the boundary lines, if necessary. Im beigefügten Video kann man sehen, wie die Begrenzungslinien der Flächen schnell ausgetauscht werden können. Die übrig gebliebene doppelte Linie lässt sich im Anschluss problemlos löschen.
