# How can I model rounding, bevels etc.?

Irregularities in the cross-sectional geometry can be mapped with point elements. They can be supplemented as a fillet, rectangle, circle or triangle or also removed from element surfaces. In this way, the area of the point element for the cross-sectional values can additionally be taken into account or excluded.
Point elements can be inserted via menu Insert -> Cross section data -> 1 5 point elements or via the corresponding button in the toolbar (see Figure 1).
No voltages are output at point elements.
Point elements are not included in the calculation of the torsional moment of inertia. This can be compensated in the dialog Calculation parameters via a correction coefficient, to B. to detect pronounced fillets.

Furthermore, corners and edges of the cross-section can be provided with radii of curvature and bends with the function "round off or bend corner". This function is called via menu Edit -> Round off or bend the corner (see picture 2). In the Corner Type section, specify whether the corner should be rounded or angled. Depending on the specification, in the Parameters section, the radius of curvature r or the shortening by the lengths l1 and l2 must be specified.
The two elements are then - without closing the dialog - in the working window by mouse click
select. In the section "Generating between elements no." become the numbers of the elements
displayed.
If the checkbox Disconnect elements is active, after creating the arc or the
new element deletes the supernatants of the original elements in the corner area. The option
Delete Corner also removes the node in the corner.

In addition, Corner Cornering lets you model corner areas in detail, without using rectangular point elements (see Figure 3). The function is called via the menu Edit -> Smooth the corner. Then click on one of the two elements in the overlap area in the working window. The relevant element side is shortened, the adjacent element side extended accordingly. A null element establishes the connection between the elements.
