Lines are the basis for generating members, surfaces and solids. They are limited by initial and end nodes. In addition, line loads and line supports can be defined at lines.

There are different line types of different complexity. Examples include polylines, arcs, or NURBS lines, but there are several more available. Depending on the complexity of the line, further intermediate nodes may be required for the line definition. There are different line types. Line loads and line supports can also be defined on lines.

A line is assigned a local line coordinate system with the x-axis running in the direction of the line. The other axes are aligned as far as possible to the global coordinate system. The line coordinate system can be adjusted by right-clicking and selecting the "Reverse Line Orientation" option. In addition, it is possible to rotate the line in the line settings.

Entering in RFEM

Lines can be entered and defined in RFEM graphically by using "Insert" → "Model Data" → "Lines" → (Select Line Type) → "Graphically", the corresponding toolbar button, or by using the tables.
