The 'Centre of Gravity' function allows you to calculate the center of gravity of an entire wall. All volumes of the selected planes are taken into account.

The center of gravity is drawn as a circle with a cross. If the center of gravity isn't visible, the wall measurement elements are disabled in the display dialog box (File - Settings - Display).

The center of gravity is also displayed on the wall plan. So that it can be switched on and off there, it is placed on a separate layer. The wall plan legend also indicates the weight of the wall and the considered levels.

This center of gravity can be used to determine the suspension points. It's important that the hook is always positioned vertically above the center of gravity, regardless of the length of the individual chain.

Center of gravity, automatic suspension

Priority of deviation: When determining the suspension points in the center of gravity function, the software first tries to find solutions without deviating from the attachment points of the traverse (AP) or the center of gravity (SW). If this is not successful, the software first tries to deviate from the attachment points of the traverse (AP); the chains or straps then no longer hang vertically. Only if this is also unsuccessful does it try to deviate from the center of gravity (SW); maintaining the center of gravity therefore has higher priority. Now, by selecting the priority, this order can be reversed, so that the software first tries to deviate from the center of gravity (SW) and only if that fails deviate from the attachment points (AP).

The frames for the suspension are searched for. The following bar types are considered: 622, 632, 311 - 318, 641. For bar type 622, the Z coordinate of the body coordinate system must be parallel to the global XoY (i.e., horizontal). This means that the vertical frames are ignored.

Point Entry: In this function, the suspension points are normally determined automatically and the combined element is transferred. If other suspension points are desired, one or two suspension points can be entered by clicking the "Point Entry" button.

▪ The points can be anywhere; only the X position is taken from them.

▪ At the entered X position, the program then determines the components for the suspension and the upper and lower points for the machining.

▪ Components and points are then transferred to the combination element, as in the automatic search.

This means that the combination elements for the suspension construction can also be used for points that are not automatically determined.
