5 A model consists of structural objects, **loads** and **finite elements**. This chapter summarizes the definition ways, the properties and the features of the structural objects.
6
7 Depending on the current **FEM-Design Module **(license you have), the available Object types are different. Although the structural objects are real 3 dimensional objects, they are 1D members and 2D planar elements (because of the finite element method) having sectional (thickness, profile etc.) and material properties. So, they can be defined as lines or regions. Some elements like point supports can be defined as points.

97.2 199 |[[image:warning.png]]|To avoid design failures of concrete, steel and timber bars (section type and material do not fit), the program checks the section type - **material** compatibility while setting the properties. The program sends an error message when it finds incompatibility definition at closing the settings dialog. But, the so-called **General material** (defined by the user) can be added to each section types.

The size (//Scale//), the filling (//Fill//) and contour (//Border//) colors are customizable. Although, section shape symbols are visible in most of the different display modes, their “best” display mode is the (% class="wikiinternallink" %)**Wireframe**(%%) mode without (% class="wikiinternallink" %)**displaying the elements’ thickness**(%%).
498 \\The //Display connections// option shows the end connection property (see (% class="wikiinternallink" %)**Beam**(%%), (% class="wikiinternallink" %)**Column**(%%) or (% class="wikiinternallink" %)**Fictitious bar connection**(%%) settings) of the bar elements. Only the free end motion components can be displayed as arrows, where a simple arrow shows a motion component by its direction and a double-headed arrow shows the axis direction of a rotation component. The fix (rigid) end connection components are never displayed. The color of an end motion component equals with the color of the proper axis of the host bar element’s local system (see before, (% class="wikiinternallink" %)**Display local system**(%%)). The size of the symbols can be set at the //Size// option.

So, for example, columns are on the “Columns” layer and the walls are on the “Walls” layer. The default color and pen width of elements’ contours/reference lines are represented by their host layers. For example, by default, walls are red, if the color of the “Walls” layer is also red.

1027 This chapter summarizes the possibilities and properties of the available supports and connections.
1028
1029 The connection with the ground (model space) can be modeled with //Supports//, while the link among structural elements can be defined with //Connections//. All support/connection components can be set to:
1030
1031 * “infinite” rigid: blocked motion/rotation,
1032 * “free”: released motion/rotation, or
1033 * semi-rigid: given stiffness value (spring) against motion/rotation.
1034
1035 **Non-linear behaviors**, independent compression and tension, elastic and plastic behaviour settings are also available for all motion and rotation components.

In that case the program sends a warning message at the end of the calculations, and you can determine the location of the problems by checking the equilibrium (//Analysis// > **Equilibrium**), the displacement/buckling and/vibration shape results of the structure. It may also happen that the model is so incorrect that calculations stops with error messages and without results.
