Export of results

In a three-dimensional model, is there a way to export the water level surface to the dxf or shape format (in polylines)? And is it also possible to export sections to dxf or shape?

In the Data panel, please double-click on Pressure. Go to the View Components panel and right-click on Zero Isosurface and export. As requested, you can export as a shape or as a dxf. However, you need to clip outside of FEFLOW using for example GIS.
