The automatic detection of integrated objects in a surface does not work.

When I try to integrate them manually into the surface, a message appears stating that the lines or openings are not located in the surface

Answer

In the case of imported structures, for example, or surfaces crooked in the ground, it often happens that the nodes are affected by inaccuracies. By default, RFEM allows for an inaccuracy of 0.5mm. If this inaccuracy is exceeded, the nodes, lines, and openings elements are no longer added automatically.
The same imprecision is tolerated even for curved surfaces (quadrangle).
However, if you still try to integrate the elements into the surface manually (Edit Surface -> A corresponding warning 929 concerning elements lying outside the surface appears.
By increasing the tolerance range with "Tools -> Regenerate model "" Although it is possible to force the detection of integrated elements, this usually results in a distorted FE mesh and thus also points of discontinuity in the FEM calculation.
The problem can be solved for plane surfaces by using the function "Edit -> Purge. To do this, you have to select the corresponding elements first. Then they are projected onto the desired plane and can then be recognized automatically.
