Open the Cladding dialog using either of the following methods:

The option defines a Cladding, that is, a surface that lets you distribute planar, linear and concentrated loads on bars, panels and supports. This object can considerably facilitate generating loads; it allows you defining real structure objects that do not participate in the load capacity of a structure, such as panel walls and roofing. You can apply planar loads (uniform or not uniform, defined on any contour or object), linear (defined by 2 points or on edges) and concentrated (force at the point) to claddings. You can also use claddings when bar loads from 3D objects (which is equivalent to defining a uniform planar load on an object) and 3D snow and wind loads are generated. A finite element mesh is not generated on a cladding; it is an auxiliary object for defining loads.

The dialog has the following parts:

At the top of the dialog:

The list field displays 3 available types of load distribution based on the load direction:

Note The trapezoidal and triangular method is used to distribute loads for all cladding types. Because distribution methods are limited to this method, you cannot define new types of load distribution. Use the Do not take truss bar into account option by selecting objects on which loads from a cladding are distributed.

A surface object is generated in the form of a face with defined cladding. A surface is defined in the same manner as a panel (by indicating an internal point or the list of linear objects).

You can also define a cladding by selecting the Geometry menu > Claddings.

Loads from claddings are distributed on all objects in the contour and plane of a cladding:

You can select objects that lie in the plane of a cladding (or of a panel for which the trapezoidal and triangular distribution is selected in a calculation model) and do not carry loads. In a real structure, these can be elements of roof bracing that do not carry the load transferred from the roofing. You can select objects using either of the following ways:

You can define a surface by assigning cladding to a face-type object for the following structure types: bar structures and shell structures. It is assumed that for volumetric structures the face object behaves like a face of a volumetric structure; you cannot define loaded surfaces on such an object. All types of loads (planar, linear, and nodal) can be applied to a cladding, except for 2 types of planar loads: hydrostatic pressure and thermal loads.
